Description
Technical field
The utility model relates to a kind of clutch, particularly relates to the novel wedge overrunning clutch of a kind of self-rotating air hammer.
Background technique
Free wheel device is applied widely in current mechanical transmission, and existing free wheel device mainly exists following shortcoming: 1) roller clutch, and cost is high, and star-wheel difficulty of processing is large, and same specification moment of torsion is less, easy to wear, and working life is short; 2) roller adds wedge block type clutch, and working life is short, poor stability; 3) keep circle composite structure, cost is high and Applicable scope is less.
Model utility content
The utility model in order to overcome the above problems provide a kind of structure simple, improve bit speed, increase Operating torque, impulsive load is large, the novel wedge overrunning clutch of self-rotating air hammer of long service life.
The technical solution of the utility model is: described clutch comprises outer ring body, inner ring body, oil ring and isolating part, described oil ring is arranged on outer ring body, described isolating part is arranged between outer ring body and inner ring body, described isolating part comprises a pair check valve case, a pair valve body support, some voussoirs, flexible link, a pair seal ring and a pair rubber seal cone, described check valve case is connected to valve body side face, between two described valve body supports, some voussoirs are set, described flexible link is arranged on the joint of voussoir and outer ring body, seal ring is respectively equipped with outside two described check valve cases, rubber seal cone is set outside described seal ring respectively.
The utility model structure is simple, raising bit speed, increase Operating torque, impulsive load are large, long service life.
