Structural characteristics of finishing mill
Finishing mill unit is combined with 10 mills, speed increasing box, support base, arc coupling, waterproof slot, waterproof plate, the protective cover, piping and guide of finishing mill. Mill frame is composed of 3 200mills and 7 150 mills, frame use top crossed 45 composition form to achieve no twisting, no contact axis, little axis and shock for equipment, besides, it decrease the center of gravity height, the stability increased as well, in the mean time, the total weigh has decrease and it is easy to maintain. Ten frames are concentrated transmission.
Roll frame is composed of roller box, bevel gearbox and spare parts of bevel gearbox.
Roller box and bevel gearbox adopt outside combinational instruction, decrease the size of bevel gearbox to decrease the weight of finishing mill, decrease the space of mills to make their structure compact. Roller box used cantilever roll loop, there is eccentric locking collar in the box to adjust roll gap. Film bearing and roll shaft are inside eccentric locking collar, taper sleeve is used to fix roll loop which is in the end of roll shaft.
Bevel gearbox is composed of box, transmission box, spiral bevel gear roll and synchronized gears. All gears are hardened grinding gear, geartooth correction is needed. The accuracy level of spiral bevel gearbox is 6 and round bevel gearbox is 5 to insure the smooth working of high speed.
Roller box and bevel gearbox are connected by bolts, a part of roller box plug into the bevel gearbox to let 2 synchronized gears in bevel gearbox meshed. Roller box and bevel gearbox are fixed by 2 locating pin, the roller box with same specification can be changed.
The axial force of the roll shaft beared by a pair of thrust ball bearings, this ball bearing mounted on the axial clearance in the absence of the resilient washer, because the very small axial clearance ball itself, therefore the roll shaft to accurately positioned in the axial direction, which ensures accurate roll rolling precision, which is to ensure the dimensional accuracy of the workpiece.
The roller shaft near the film bearing is designed in the form with taper, so the roller shaft can bear uniform load distribution even it is bend. So the lifetime of roller can be improved.
The adjustment of roll gap is to rotate feed screw with left and right thread and nut. When the 2 eccentric rotated relatively, the distance of 2 rollers changed with the symmetrical eccentric relative movement of eccentric locking collar, so the location of former roller line and guide can be maintain.
Roller loop is tungsten carbide, it is connected on the cantilever roll shaft, we use the specific hydraulic changing roll equipment to replace roll loop, it is convenient and easy.

Types of Shaft Collars
Quick-clamp shaft collars
Quick-clamp shaft collars are a convenient option for tightening and loosening shafts. Unlike traditional bolts, quick clamps do not require any tools to install and adjust them. These collars come with flush handles and are designed to reduce production downtime. They also feature high-strength tension adjustment screws for compatibility with a wider range of shaft tolerances.
Quick-clamp shaft collars are offered in a variety of styles. CZPT, for example, offers a unique style of quick-clamp shaft collars with an integral lever. This lever sits flush against the outside diameter and is finger actuated. In addition, this design includes a tension-adjustment screw that can be adjusted according to the application’s requirements. Another style of quick-clamp shaft collar is a one-piece clamping collar with an integrated handle. It is ideal for low-rpm applications, and is designed to be a quick and simple solution for frequent shaft changeovers.
Quick-clamp shaft collars have an adjustable locking force generated by an eccentric lever and are very easy to install. They are available in one and two-piece clamp-type styles, and come in more than thirty standard sizes. They are available with round, square, and threaded bores. Additionally, you can choose to have them painted or customized.
Single split shaft collars
Single split shaft collars are a common choice for new installations. They provide easy installation and disassembly, which helps to minimize labor and downtime. They are also designed with full seating torque of the set screws, which evenly distributes forces throughout the shaft circumference. As a result, they provide greater holding power.
These shaft collars are available in various materials. They are typically made from different types of steel, including stainless steel and aluminium steel. They can also be made from nylon. The latter is available with different finishes, including black oxide. These are also available in custom sizes. These shaft collars are made to fit specific applications.
Single split shaft collars are available in a variety of sizes to fit a wide range of shaft diameters, from 1/8″ to 4 15/16″. The material used for the shaft should be softer than the material used for the set screw. They are marked with the bore size and are available in non-plated, chrome-plated, and black oxide coated materials.
Heavy-duty shaft collars are designed to hold a large amount of torque. They are available in two-piece clamp and one-piece clamp styles and offer up to 25 percent more holding force than standard collars. They are also available in a variety of materials, including proprietary black oxide finish, 1215 lead-free steel, 303 stainless steel, and high-strength 2024 aluminum.
Single split shaft collars are generally easy to install and remove. The design of these collars allows the shaft to fit into it evenly, which improves holding power. They also eliminate the need to remove or disassemble other components of the shaft. Additionally, they are easy to adjust and can work with virtually any shaft.
Single split shaft collars come in two-piece and one-piece styles. One-piece shaft collars are simpler to install and do not damage the shaft. Clamp-style collars are easy to use and do not require tools. They are designed to be hand-adjustable. These collars are recommended for light-duty applications. They are available in a wide range of threaded bore sizes. They also come in various styles, including ring-style and set-screw collars.
Set-screw shaft collars
Set-screw shaft collars are made of different materials, including steel, aluminum, and zinc plated steel. They are available in various widths and sizes. They can be used in aerospace, defense, and construction applications. Some types are standard, while others are custom-made.
A shaft collar has three primary functions: it holds a component in place, locates the component on a shaft, and creates an attachment between the shaft and another component. The design of a shaft collar depends on several factors, including the material, diameter, and geometry of the shaft.
One of the most common uses of shaft collars is to secure bearings and sprockets to shafts. In some cases, they also act as mechanical stops. For example, a two-piece clamp collar will wrap around the shaft without leaving any marks, while a set-screw collar will lock onto a shaft with a set screw. These types of collars can be used on predrilled and soft shafts.
Another advantage of set screw shaft collars is that they can be manufactured in a lightweight style for space-constrained applications. Another benefit is their ability to hold twice as much load as standard shaft collars. These collars are also available with a keyway, which makes them suitable for shafts with a key.
Another advantage of set-screw shaft collars is their safety. They were invented in the recessed socket screw industry and have become an industry standard. They prevent the shaft from sliding and causing a flanged bearing to come out. They are easy to install and remove, and they are ideal for light-duty applications.
Clamp style shaft collars are also available in one-piece and two-piece designs. This type of collar is unique in that it can be removed without damaging the shaft. They are also adjustable and can fit virtually any shaft. Their clamping force is evenly distributed around the shaft, so they are significantly safer than set screw collars, which use point-contact clamps.
Hinge shaft collars
The International series is a two-piece shaft collar with metric outer diameters, metric widths, and inch bores. These collars are suitable for many different types of applications, and are available in a variety of materials and bore sizes. They are available in 1215 lead-free steel with black oxide finish, high strength 2024 aluminum, and 303 stainless steel.
Custom Hinged Shaft Collars are a great choice for applications requiring quick and easy adjustment, especially in remote locations. They are available in a variety of materials, including steel, stainless steel, aluminum, and brass. You can even get custom-made collars for unusually shaped shafts.
Hinge shaft collars are similar to two-piece shaft collars in many ways. They allow easy disassembly and reassembly along the shaft and are usually the preferred choice in harsh environments. Hinge shaft collars have a simple design, allowing them to be installed quickly and easily. They also provide superior holding power. If you’re considering a hinge shaft collar for your application, it is important to consider how it will be used.
Hinge shaft collars serve as precise stops and spacers for different laboratory equipment. They can also be used on plastic, glass, and thin-walled tubes. They are often used in medical equipment, where the need for accuracy is paramount. They also serve as guides in optical measuring instruments. They are also useful in trucks and off-road vehicles, where they serve as mechanical stops.
Hinge shaft collars can be purchased in two-piece or one-piece designs. They can be adjusted using a single screw or lever. They can be installed and removed without causing any damage to the shaft. Unlike set screw collars, they don’t require tools. This makes them ideal for applications where access to the shaft is difficult or impossible. The advantages of these collars include improved safety and security.
