Abstract
Provided is a retainer positioning mechanism of a freewheel clutch. The positioning mechanism provided is characterized in that a retainer is connected to an inner ring cam, and the connection is in a positioning front edge structure, the positioning mechanism is arranged at one side of the spring end of the retainer, or one side far away the spring end, or both of the two sides. The positioning mechanism is advantageous in that the actual wedge-caulking number of the roller is improved to enable the contact stress of the roller, the inner ring cam and an outer ring gear to approximate to the theoretical value; the components in the retainer are subjected to the processing of quenching, carburizing quenching, carbonitriding quenching or nitridation etc. to improve the impact resistance capability of the roller during the wedge-caulking and the disengagement; the deviated load of the roller resulted from the existing related coaxiality and verticality errors during the manufacturing and installing processes is improved to prevent the roller and the retainer from early wearing, thereby being in favor of improving the work reliability of the freewheel clutch.
Description
Technical field
The utility model relates to engineering machinery transmission device technical field, and especially a kind of being used for realizes throwing off retainer positioning means in the roller-type overrunning clutch of low speed wedging transmitting large torque at a high speed.
Background technique
At present; Free wheel device uses quite general in engineering machinery transmission device technical field; Its structure is mainly by outer ring gear; Be bound up on the countershaft-gear through bolt and interior ring cam and gland, be sleeved on the outer retainer of cam ring, and the roller in the raceway of ring cam constitutes in being contained in.The wedge space that the interior raceway of interior ring cam and outer ring gear forms; Retainer correctly remains in the space of wedge roller, and spring is installed in the end face groove of retainer, and an end withstands on retainer; The other end withstands on the gland; Make retainer promote the little end motion of roller together, outer ring gear and interior ring cam wedging are in the same place towards the wedge space, and transferring power and moment of torsion etc.
Mainly there is following defective in it: do not cooperate between (1) retainer and the interior ring cam, the actual wedging of roller will be counted be less than the roller sum, the contact stress of roller, interior ring bulge loop and outer ring gear is improved greatly.(2) because each part in manufacturing and installation process, exists relevant coaxality and perpendicularity equal error, make each roller unbalance stress, roller tilts, and causes roller load to occur being partial to, and roller and retainer produce premature wear etc.
Summary of the invention
It is more reasonable that the purpose of the utility model just provides a kind of structure, and can improve retainer positioning means in the free wheel device in life-span effectively.
The solution of the utility model is such: retainer is connected with interior ring cam in the structure of the utility model, and its linkage structure is the positioning spigot structure.
The structure of positioning spigot has:
1, described positioning spigot structure is in retainer mounting spring end one side, and the interior ring cam cylindrical place of homonymy has the cylindrical positioning spigot, has the internal diameter positioning spigot at retainer, and retainer is connected at the positioning spigot place with interior ring cam.
2, described positioning spigot structure be at retainer away from mounting spring end one side, the interior ring cam cylindrical place of homonymy has the cylindrical positioning spigot, has the internal diameter positioning spigot at retainer, retainer is connected at the positioning spigot place with interior ring cam.
3, described positioning spigot structure is away from mounting spring end one side at retainer mounting spring end one side and retainer; Interior ring cam cylindrical both sides have the cylindrical positioning spigot; Have the internal diameter positioning spigot in the retainer both sides, retainer is connected at the positioning spigot place with interior ring cam.
The utility model has the advantages that:
(1) the actual wedging number of raising roller, the contact stress that makes roller, interior ring bulge loop and outer ring gear is near theoretical value.
(2) part adopts quenching, carburizing and quenching, carbon nitrogen it oozes and quenches or nitriding treatment etc. in the retainer, improves roller shock-resistant ability in wedging and disconnecting process.
(3) improved because in manufacturing and the installation process, the relevant coaxality of existence and the deflection load of roller that vertical error causes have avoided roller and retainer to produce premature wear.Avoid roller and retainer to produce premature wear, helped improving the functional reliability of free wheel device.
