Description

Technical Field

[0001] The utility model belongs to the technical field of friction wheels, and particularly relates to a friction wheel. Background Technique

[0002] A rotary screen, also known as a drum screen, is a screening device widely used in industries such as mining, building materials, chemical engineering, and food. When driving the rotary screen to rotate, a friction wheel is generally used.

[0003] The existing friction wheels have deficiencies. When the friction wheel works, the noise generated by friction is very loud, and the noise pollution is serious. The noise will interfere with the language communication between people, making it difficult for the staff to hear the speech content of the other party clearly, resulting in poor communication. This will not only affect the work progress but also may cause misunderstandings and mistakes. In view of this, we propose a friction wheel. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a friction wheel to solve the problems raised in the above background technique.

[0005] In view of this, the utility model provides a friction wheel, including:

[0006] A friction wheel steel body, on which an annular colloid is sleeved. A plurality of through grooves are opened on the inner wall of the annular colloid. Plug plates fixed to the friction wheel steel body are inserted into the plurality of through grooves. Fixing plates are arranged on both sides of the friction wheel steel body. A plurality of limiting grooves are opened on both sides of the annular colloid. Limiting plates fixed to the corresponding fixing plates are inserted into the limiting grooves. A plurality of limiting holes are opened on both sides of the friction wheel steel body. Cylinders fixed to the corresponding fixing plates are inserted into the limiting holes. Fixing screws are installed in the fixing plates in a threaded manner. One end of the fixing screw extends into the friction wheel steel body. Through holes are opened on the fixing plates.

[0007] In this technical solution, during installation, the staff can align several through grooves on the inner wall of the annular colloid with several insertion plates on the steel body of the friction wheel one by one. Subsequently, displace the annular colloid towards the steel body of the friction wheel. At this time, several insertion plates on the steel body of the friction wheel will respectively enter several through grooves on the inner wall of the annular colloid until the insertion plates are completely inserted into the corresponding through grooves. Then, align several limiting plates on one fixing plate with several limiting grooves on one side of the annular colloid. At this time, several cylinders on the fixing plate will be respectively aligned with several limiting holes on one side of the steel body of the friction wheel. Subsequently, displace the fixing plate towards the steel body of the friction wheel so that the limiting plates are inserted into the corresponding limiting grooves. At this time, the cylinders will be inserted into the corresponding limiting holes. Then, through several fixing screws on the fixing plate, the staff can use a screwdriver to rotate the fixing screws. Under the action of the thread, the fixing screws will rotate and displace towards the steel body of the friction wheel, so that one end of the fixing screw is threadedly installed into the steel body of the friction wheel, making the fixing plate fixed to one side of the steel body of the friction wheel. At this time, one of the fixing plates will be installed. Through the above operations, another fixing plate can be installed on the other side of the steel body of the friction wheel. At this time, the annular colloid will be fixed by the limiting plates on the two fixing plates, and under the action of several insertion plates, the annular colloid will not rotate or slide on the steel body of the friction wheel. When the annular colloid is severely worn after long-term use and needs to be disassembled, the above operations can be performed in reverse to complete the disassembly of the annular colloid.

[0008] In the above technical solution, further, several of the through grooves and several of the limiting grooves are annularly and equidistantly distributed.

[0009] In this technical solution, it is ensured that the annular colloid can be fixed more stably.

[0010] In the above technical solution, further, the cross-section of the through groove and the insertion plate is an isosceles trapezoid structure.

[0011] In this technical solution, it is ensured that the insertion plate is more stable after being inserted into the through groove.

[0012] In the above technical solution, further, the fixing screw is threadedly connected to the steel body of the friction wheel.

[0013] In this technical solution, under the action of the thread, when rotating the fixing screw, it is ensured that the fixing screw can displace in the steel body of the friction wheel.

[0014] In the above technical solution, further, the cylinder and the limiting plate are integrally formed with the fixing plate, and several of the limiting holes and several of the fixing screws are annularly and equidistantly distributed.

[0015] In this technical solution, the structure between the cylinder, the limiting plate and the fixing plate is ensured to be stable; it is ensured that the fixing plate can be fixed more stably under the cooperation of a number of limiting holes, a number of cylinders and a number of fixing screws.

[0016] In the above technical solution, further, both the limiting groove and the limiting plate are arc-shaped structures.

[0017] In this technical solution, it is ensured that the limiting groove can be opened on the annular colloid, so that the limiting plate can be inserted into the limiting groove, thereby fixing the annular colloid.

[0018] In the above technical solution, further, the centers of the through holes and the fixing plate are on the same horizontal line.

[0019] In this technical solution, it is ensured that under the action of the two through holes, the friction wheel steel body can be normally installed, and the fixing plate is prevented from blocking the installation holes on the friction wheel steel body.

[0020] The beneficial effects of the present utility model are:

[0021] 1. For this friction wheel, through the provided annular colloid, when the friction force is in operation, the annular colloid reduces the noise problem generated by friction during the driving of the rotary vibrating screen, greatly reducing noise pollution. Moreover, the annular colloid is lighter in weight and more environmentally friendly.

[0022] 2. For this friction wheel, through the cooperation of the provided fixing plate, fixing screws, limiting groove, insertion plate, through groove, limiting plate, limiting hole and cylinder, it is ensured that the severely worn annular colloid can be disassembled and replaced, preventing the severely worn annular colloid from affecting the operation of the rotary vibrating screen, and the replacement method is convenient and fast.
