Abstract

The invention relates to a novel sprag overrunning clutch for a novel self-rotation air hammer. The clutch comprises an outer ring body, an inner ring body, elastic check blocks, an elastic collar, pin rollers, sealing rings and an oil cup, wherein the elastic check blocks, the elastic collar, the pin rollers and the sealing rings are arranged between the outer ring body and the inner ring body; two elastic check blocks are arranged; the elastic collar is arranged between the two elastic check blocks; the pin rollers are respectively arranged on the outer sides of the elastic check blocks; the outer sides of the pin rollers are provided with the sealing rings; the oil cup is arranged on the outer ring body. The novel sprag overrunning clutch is simple in structure, large in impulse load and long in service life, the drilling speed is improved, and the operation torque is increased.

Description

technical field [0001] The invention relates to a clutch, in particular to a novel sprag overrunning clutch for a novel self-rotating air hammer. Background technique [0002] Overrunning clutches are widely used in current mechanical transmissions. The existing overrunning clutches mainly have the following disadvantages: 1) Roller clutches, high cost, difficult star wheel processing, small torque of the same specification, easy to wear, long service life Short; 2) The roller plus sprag clutch has a short service life and poor stability; 3) The combined structure of the retaining ring has high cost and a small scope of application. Contents of the invention [0003] In order to solve the above problems, the present invention provides a novel wedge overrunning clutch for a self-rotating air hammer with simple structure, increased drilling speed, increased working torque, large impact load and long service life. [0004] The technical solution of the present invention is: ...
