Abstract
The invention relates to a cam type friction clutch, which comprises a clutch body, a driving shaft, a driven shaft, a cam lever and a friction disc. The clutch body is fixedly arranged on the driving shaft. A horizontal pressure block is arranged at the top end of the clutch body. A ring groove is reserved in the lower part of the pressure block. A first sleeve is arranged on the driven shaft through a sliding key. The lower end of the friction disc is arranged on the first sleeve, and the upper end of the friction disc is pressed against the lower part of the pressure block. The left side of the friction disc is attached to the clutch body. A pressure plate is attached to the right side of the friction disc, and comprises a side baffle plate. A second sleeve is idly sleeved on the right side of the first sleeve on the driven shaft. The lower end of the cam lever is hinged with the second sleeve, and the upper end of the cam lever is embedded into the ring groove of the pressure block. A bump part capable of resisting the pressure plate is arranged on the middle part of the cam lever, and is hinged with the side baffle plate of the pressure plate. The cam type friction clutch is simple in structure and convenient to operate; and the driving shaft and the driven shaft are engaged and disengaged by the pressing of the cam lever and friction force between the friction disc and the clutch body.
Description
Technical field
The invention belongs to mechanical engineering technical field, be specifically related to a kind of cammingly friction clutch.
Background technique
The cammingly clutch generally is to utilize eccentric cam wedge structure and the wedge action of driving and driven part, the one direction transmitting torque, have simple in structure, bearing capacity by force, be suitable for the characteristics such as high rotating speed, good reliability, maintenance be easy.Often there are the defectives such as the moving clutch of complex structure, inconvenient operation, principal and subordinate is unstable in existing cammingly clutch.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple in structure, moving stable cammingly friction clutch of clutch of principal and subordinate.
In order to solve the problems of the technologies described above, the present invention adopts following technological scheme:
A kind of cammingly friction clutch, comprise clutch body, driving shaft, driven shaft, cam lever and friction disk, described clutch body is fixed on the driving shaft, the clutch body top has the briquetting of level, the briquetting bottom has circular groove, be provided with the first sleeve by feather key on the driven shaft, described friction disk lower end is installed on the first sleeve, the friction disk upper end props up the briquetting bottom, friction disk left side applying clutch body, fit pressing plate be set in the friction disk right side, pressing plate comprises lateral retaining plate, and the right side that is positioned at the first set cylinder on the driven shaft is set with the second sleeve, cam lever lower end and the second sleeve are hinged, the cam lever upper end embeds in the circular groove of briquetting, and the cam lever middle part is provided with the lug boss that can prop up pressing plate, and the lateral retaining plate of lug boss and pressing plate is hinged.
The present invention is because friction disk left side and clutch body applying, friction disk is installed in again on the first sleeve, the first sleeve links to each other with driven shaft by feather key, therefore when friction disk is compacted, by the effect of the frictional force between friction disk and the clutch body, clutch body rotates with driving shaft, and friction disk will rotate with clutch body, and then driving the driven shaft rotation, the running of master and slave moving axis is connected.
Working procedure of the present invention is as follows: when making the second sleeve slide to the right side, the lug boss of cam lever will unclamp friction disk, friction disk disconnecting clutch body, frictional force between friction disk and the clutch body disappears, driving shaft can not drive friction disk again and rotate, and the motion between driving shaft and the driven shaft is cut off; When making the second sleeve slide to the left side, the lug boss pressing friction dish of cam lever, produce frictional force between friction disk and the clutch body, clutch body drives friction disk and rotates together, friction disk and then drive driven shaft rotate together, the motion of master and slave moving axis is switched on, and this moment, cam lever together rotated in company with clutch body.The present invention is simple in structure, easy to operate, and the clutch that compression and the frictional force between friction disk and the clutch body by cam lever realizes master and slave moving axis makes more stable transmission, better effects if.
Further, also be provided with the stage clip of level on the second sleeve, described stage clip one end is connected with the second sleeve, and the other end links to each other with the pole that is fixedly installed.After the second sleeve slides to the right and cuts off transmission between the master and slave moving axis, stage clip is in impaction state, when act on power that the second sleeve slides is to the right disappeared after, the stage clip restoring force effect under, the second sleeve will be slided left, cam lever compresses friction disk through pressing plate, realizes the automatic connection of master and slave moving axis motion.
Further, described friction disk has two, the setting that fits together of two friction disks.Two friction disks are set, increasing friction force during applying, transmission is more stable.
Description of drawings
