Abstract
The utility model relates to a cam-type friction clutch which comprises a clutch body, a driving shaft, a driven shaft, a cam lever and a friction plate. The clutch body is fixed on the driving shaft. A horizontal pressing block is arranged at the top end of the clutch body. A ring-shaped groove is formed on the lower portion of the pressing clock. A first sleeve is arranged on the driven shaft through a feather. The lower end of the friction plate is installed on the first sleeve. The upper end of the friction plate is abutted against the lower part of the pressing block. The left side of the friction plate is attached to the clutch body, and a pressing plate is arranged on the right side of the friction plate in an attached mode. The pressing plate comprises a side baffle. A second sleeve is sleeved on the right side of the first sleeve on the driven shaft. The lower end of the cam lever is in hinge joint with the second sleeve, and the upper end of the cam lever is embedded inside the ring-shaped groove of the pressing block. A protrusion part which is capable of abutting the pressing plate is arranged in the middle part of the cam lever. The protrusion part is in hinge joint with the side baffle of the pressing plate. The cam-type friction clutch is simple in structure and convenient to operate. On-off of the driving shaft and the driven shaft can be achieved through pressing tightly of the cam lever and force of friction between the friction plate and the clutch body.
Description
Technical field
The utility model belongs to mechanical engineering technical field, is 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, and folk prescription is to transmitting moment of torsion, have simple in structure, bearing capacity by force, be suitable for characteristics such as high rotating speed, good reliability, maintenance be easy.Often there are defectives such as complex structure, inconvenient operation, the moving clutch instability of principal and subordinate in existing cammingly clutch.
The model utility content
The technical problems to be solved in the utility model 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 utility model 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 first sleeve by feather key on the driven shaft, described friction disk lower end is installed on 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 first sleeve on the driven shaft is set with second sleeve, cam lever lower end and 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 utility model is because friction disk left side and clutch body applying, friction disk is installed in again on first sleeve, 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.
The utility model working procedure is as follows: when making 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 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 utility model is simple in structure, easy to operate, by cam lever compress and friction disk and clutch body between frictional force realize the clutch of master and slave moving axis making more stable transmission, better effects if.
Further, also be provided with the stage clip of level on second sleeve, described stage clip one end is connected with second sleeve, and the other end links to each other with the pole that fixedly installs.After 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 second sleeve slides is to the right disappeared after, the stage clip restoring force effect under, 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, increase frictional force during applying, transmission is more stable.
