Description
Technical field
The utility model relates to a kind of gear overrunning clutch.
Background technique
Overrunning clutch is made up of outer ring, axle and clutch dog between the two, clutch dog is made up of asymmetric cambered surface, when the rotation of outer ring clockwise direction, clutch dog is in locking state, the outer ring drives axle rotation together, when the outer ring counterclockwise rotates, clutch dog is in relaxed state, and the outer ring can not drive axle rotation together.Setting means different according to outer ring and axle motion state, overrunning clutch can develop, when outer ring or axle when remaining static, overrunning clutch just develops into uni-directional brake, as shown in Figure 5, rotating shaft 3 by key 8 and also cap 7 fixedly connected with gear ring 1, be connected with support 4 with two rolling bearings 2, overrunning clutch 6 is installed between two rolling bearings 2, fixedly connected with support 4 with straight pin 5 in its outer ring, gear ring 1 drives rotating shaft 3 and can only rotate and can not counterclockwise rotate by clockwise direction, forms uni-directional brake.Not only can use uni-directional brake in the gear drive, some occasion needs the outer ring of overrunning clutch and axle to rotate, but direction transmitting torque only, oppositely then skid, and often structure is compact, and existing overrunning clutch is directly used, and can not satisfy usage requirement.
The model utility content
The technical problems to be solved in the utility model is: a kind of gear overrunning clutch is provided, and its compact structure, easy to operate, clutch is convenient, is the switching of practicable clutch state as long as change turning to of gear.
The utility model solves technological scheme that its technical problem adopts: a kind of gear overrunning clutch, have overrunning clutch and gland, be set with axle sleeve on the overrunning clutch, one end of axle sleeve has and the incorporate gear of axle sleeve, the other end and the gland of axle sleeve are bolted to connection, fixedlying connected with axle sleeve in the outer ring of overrunning clutch, between the cylindrical of axle sleeve and the endoporus of support rolling bearing is housed.
For making the gear overrunning clutch simple in structure, fixedly connected by pin or tight fixed bolt with axle sleeve in the outer ring of described overrunning clutch.
For moment of torsion that the gear overrunning clutch is transmitted big, described axle sleeve inner headed face has limited step, one end face of overrunning clutch contacts with limited step, and the end face of gland contacts with the end face of the other end of overrunning clutch and axle sleeve, and the outer ring of overrunning clutch is connected by key with axle sleeve.
Be further to improve the radially bearing capacity of gear overrunning clutch, between the axle sleeve of gear end and transmission shaft, block bearing be housed.
For further improving the radially bearing capacity of gear overrunning clutch, described rolling bearing is a double-row bearing.
For further reducing cost, make the engagement sleeve compact structure, described rolling bearing is no inner ring rolling bearing, has the raceway of rolling element on the periphery of axle sleeve.
For reaching simple in structure, cost is low, the purpose that clutch is effective, described overrunning clutch comprises transmission shaft, is sleeved on outer ring on the transmission shaft and the clutch dog in a plurality of clutch dog raceway that is installed on the outer ring with one heart, described clutch dog has the camming surface of being made up of the asymmetric arc surface of plurality of sections, and camming surface contacts with the clutch dog raceway of outer ring.
The beneficial effects of the utility model are, gear overrunning clutch of the present utility model has compact structure, and easy to operate, clutch is characteristics easily, are the switching of practicable clutch state as long as change turning to of gear.
