Description

A cylindrical cam mechanism Technical Field

[0001] This utility model relates to the field of cylindrical cam mechanism technology, and specifically to a cylindrical cam mechanism. Background Technology

[0002] A cylindrical cam mechanism is a higher pair mechanism composed of three basic components: a cam, a follower, and a frame. The cam is a component with a curved profile or a groove, and it is generally the driving component, performing constant speed rotary motion or reciprocating linear motion.

[0003] Existing cylindrical cam mechanisms work by creating a helical groove on a cylinder. During cylinder rotation, a linkage within the groove drives a crossbar to reciprocate along the groove's direction. However, the high friction between the linkage and the groove during transmission leads to rapid wear, affecting transmission stability and consequently impacting the load connected to the crossbar. This results in poor performance and a short lifespan. Therefore, a new cylindrical cam mechanism is urgently needed to address these issues. Summary of the Invention

[0004] (a) Technical problems to be solved

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a cylindrical cam mechanism, including a bracket, in which a cylinder is installed. A spiral groove is formed on the surface of the cylinder, and a linkage rod is provided in the spiral groove. A crossbar is fixed at the top of the linkage rod, and a liquid storage chamber is formed inside the linkage rod. A sealing cover is provided at the upper end of the liquid storage chamber. A flow regulating valve is provided on the linkage rod, and a nozzle is connected to the output port of the flow regulating valve. A transparent plate is provided on one side wall of the linkage rod, and a scale line is provided on one side of the transparent plate.

[0008] Furthermore, the cylinder is rotatably mounted inside the bracket, and a key shaft is reserved in the middle of one end of the cylinder.

During the use of the cylindrical cam mechanism, the storage chamber stores lubricating oil, and the flow regulating valve controls the flow rate of the lubricating oil, which is then injected through the drip nozzle into the connection between the linkage rod and the spiral groove. This lubricates the linkage rod, reduces its wear rate, ensures transmission efficiency, and extends its service life, resulting in superior performance. Attached Figure Description
