Description
Technical field
The present invention relates to technical field of bearings, a kind of micro-reducer that is particularly useful for micro-reducer is with the special-shaped crossed roller bearing of integrated type.
Background technique
Speed reducer be a kind of can transferring power, change the mechanism of rotating speed, be widely used in the machinery of every field.Along with development of science and technology to speed reducer require increasingly high, simultaneously also to having higher requirement as the bearing of speed reducer strength member.Certain micro-reducer is made up of housing, outer ring (or inner ring) separated type crossed roller bearing and reducing gear three parts.Crossed roller bearing is installed in enclosure interior, and bearing inner race links to each other with the reducing gear that is installed in equally in the housing, speed reducer of whole formation.There is following problem in this speed reducer:
1. Bearing Installation receives the restriction in enclosure interior space in enclosure interior, and the less bearing of boundary dimension can only be installed in speed reducer inside.And boundary dimension little bearing has also limited the maximum performance that speed reducer can not have been given play to reducing gear on bearing capacity, integral rigidity, rotating speed;
2. the divergence type bearing also is not easy to the installation and maintenance dismounting;
3. because the speed reducer weight that speed reducer shell and bearing are formed is heavier, there is the applications of weight requirement limited in robot etc.
Summary of the invention
In order to overcome the deficiency that existing technology exists, the present invention provides the preparation method of a kind of micro-reducer with the special-shaped crossed roller bearing of integrated type, is used for substituting the shell and the separated type crossed roller bearing of existing micro-reducer.It can solve bearing capacity, the rotating speed problem of speed reducer, improves the bearing capacity of speed reducer effectively, improves the limit speed of speed reducer, makes complete machine convenient disassembly in using maintenance.
For realizing aforesaid goal of the invention, the present invention adopts following technological scheme:
A kind of micro-reducer is with the preparation method of the special-shaped crossed roller bearing of integrated type, adopts the special-shaped crossed roller bearing of integrated type to substitute by what outer ring or inner ring separated type crossed roller bearing combined with reducer shell and forms body, and its step is following:
1), confirm the length of integrated type crossed roller bearing outer ring, the length of bearing outer ring comprises the length of the shell dimension and the bearing inner race 2 of speed reducer;
2), bearing enclose all adopts monolithic construction, on the bearing outer ring external diameter, opens a plunger hole, the rolling element of bearing---roller and spacing block are loaded in the bearing through plunger hole;
3), roller and spacing block load accomplish after with plunger shutoff plunger hole, and plunger and bearing outer ring are become one with the spring pin hole non-movable piston of spring pin through bearing face;
4), the bearing inner race exterior edge face increases the tapped hole that is used to connect other rotating mechanism.
A kind of micro-reducer is with the preparation method of the special-shaped crossed roller bearing of integrated type, and said spacing block adopts the self lubricity plastics that reduce friction torque between the rolling element, improves the limit speed of bearing; Said plastics adopt nylon material.
Because adopt aforesaid technological scheme, the present invention has following superiority:
A kind of micro-reducer is with the preparation method of the special-shaped crossed roller bearing of integrated type; The inside and outside circle of bearing all adopts integral design; Make the outer ring or the inner ring of divergence type bearing become integral body; On the bearing outer ring external diameter, open a plunger hole, the roller of bearing and spacing block are loaded in the bearing through plunger hole, have so not only overcome the integral rigidity that divergence type crossed roller bearing raceway repeats installation errors but also increases crossed roller bearing.Spacing block adopts nylon to make, and utilizes the self lubricity of plastics to reduce the friction torque between the rolling element, has improved the limit speed of bearing.

Embodiment
Below in conjunction with accompanying drawing and instance the present invention is described further.
A kind of micro-reducer adopts the special-shaped crossed roller bearing of integrated type to substitute group and the body that is combined with reducer shell by outer ring (or inner ring) separated type crossed roller bearing with the preparation method of the special-shaped crossed roller bearing of integrated type, and its step is following:
1), confirm the length of integrated type crossed roller bearing outer ring, the length of bearing outer ring comprises the length of the shell dimension and the bearing inner race 2 of speed reducer;
2), the inside and outside circle of bearing all adopts monolithic construction, opens a plunger hole at bearing outer ring, the rolling roller of bearing and spacing block are loaded in the bearing through plunger is empty;
3), roller and spacing block load accomplish after with plunger shutoff plunger hole, and plunger and bearing outer ring are become one with the spring pin hole non-movable piston of spring pin through bearing face;
4), the bearing inner race exterior edge face increases the tapped hole that is used to connect other rotating mechanism.
A kind of micro-reducer is with the preparation method of the special-shaped crossed roller bearing of integrated type, and said spacing block adopts the self lubricity plastics that reduce the friction torque between the rolling element, improves the limit speed of bearing; Said plastics adopt nylon material.
