Problems solved by technology

[0002] Cylindrical cam mechanisms are widely used in automatic production lines and equipment in light industry, medicine, food packaging and other production processes, but due to the structural characteristics of general cylindrical cam mechanisms, there is a certain gap between the working profile of the cylindrical cam and the rollers , will produce traverse impact when the mechanism moves, and thus cause vibration, noise and wear

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and implementation.

[0013] see figure 1 , a cylindrical cam mechanism with large and small rollers, including a driven turntable 2 and a cylindrical cam (1), the cylindrical cam 1 is provided with a large groove A and a small groove B, and the driven turntable 2 is provided with There are roller two (4) and roller one 3, and roller two 4 and roller one 3 are rollingly connected with cylindrical cam 1 through groove A and groove B. When the cam mechanism moves, it rolls in the two grooves respectively.

[0014] The section and height of the first roller are smaller than the section and height of the second roller. Described roller one is a small roller, and roller two is a large roller.

[0015] The first roller 3 and the second roller 4 are spaced apart.

[0016] The first roller is connected with the driven turntable 2 through the first pivot pin; the second roller...

Abstract

The invention relates to a cylindrical cam mechanism with big and small rollers. The cylindrical cam mechanism comprises a driven turntable and a cylindrical cam, wherein a big groove A and a small groove B are formed in the cylindrical cam, and a roller II and a roller I are arranged on the driven turntable and connected with the cylindrical cam through the groove A and the groove B in a rolling manner. When the cylindrical cam mechanism moves, the cylindrical cam mechanism rolls in the two grooves; a contact surface of the roller I and the groove B in the cylindrical cam and a contact surface of the roller II and the groove A in the cylindrical cam are opposite in direction, and the contact deformation of the roller I and a profile surface and the elastic deformation of a pin shaft with less stiffness on the roller I are utilized, so that the roller II simultaneously makes contact with the two corresponding grooves in the cylindrical cam and reversely compress the respective groove, the impact and vibration caused by the rollers and wheel groove clearance are avoided, and the good dynamic characteristic of the cylindrical cam mechanism can be ensured.

Description

technical field [0001] The invention relates to a cylindrical cam mechanism provided with large and small rollers. Background technique [0002] Cylindrical cam mechanisms are widely used in automatic production lines and equipment in light industry, medicine, food packaging and other production processes, but due to the structural characteristics of general cylindrical cam mechanisms, there is a certain gap between the working profile of the cylindrical cam and the rollers , will produce a transverse impact when the mechanism is moving, and thus cause vibration, noise and wear. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the object of the present invention is to provide a cylindrical cam mechanism with large and small rollers, which can eliminate the gap and improve the dynamic performance of the cylindrical cam mechanism. [0004] In order to achieve the above object, the technical solution adopted by the pr...
