Description

Chain-type transmission cam transmission mechanism

Technical Field

The utility model relates to a chain drive's cam drive mechanism is applied to mechanical press, belongs to mechanical engineering technical field.

Background

When an eccentric shaft of a mechanical press adopts a rotating shaft structure, a traditional cam transmission mechanism adopts a mode of directly connecting with a flange shaft at the end of the eccentric shaft through a coupling, the coaxiality of the two shafts is difficult to adjust and ensure, and the coupling is frequently damaged due to large vibration of the press, so that a user stops the machine, the coupling is frequently replaced, and unnecessary loss is caused; meanwhile, the traditional mechanism can only be connected with one group of cams and cannot meet the requirements of users.

Disclosure of Invention

The utility model aims to solve the technical problem that to the defect that prior art exists, a chain drive's cam drive mechanism is provided.

In order to solve the technical problem, the utility model provides a chain-driven cam transmission mechanism, which comprises a bracket, a first chain wheel, a chain, a second chain wheel, a cam shaft, a rotary encoder, a gear and an eccentric shaft, wherein the first chain wheel is fixed at the shaft end of the eccentric shaft, the second chain wheel is fixed at one end of the cam shaft, the other end of the cam shaft is connected with the rotary encoder, and the first chain wheel and the second chain wheel are driven by the chain; and a first protective cover and a second protective cover are arranged on the transmission mechanism.

The camshaft is fixed on the bracket through a bearing.

An oil receiving box and an oil return pipeline are arranged below the cam transmission mechanism.
