Abstract
The utility model relates to the technical field of bearings and discloses an outer ring of an integrated special-shaped crossed roller bearing for a miniature reducer. One end in the outer ring of the integrated special-shaped crossed roller bearing is provided with a speed reducing mechanism, and the other end therein is provided with an inner ring of the bearing. A roller path of the outer ring of the bearing is correspondingly provided with at least one radial plunger holes, and plugging rollers and plungers of separation blocks are arranged in the plunger holes. A spring pin arranged in a spring pin hole on an end face of the outer ring 1 of the bearing is integrally connected with the plungers. By the aid of the outer ring of the integrated special-shaped crossed roller bearing for the miniature reducer, rated load of the bearing can be increased, bearing capability and limit rotating speed of the whole reducer can be improved, rigidness and strength of the bearing can be enhanced, whole size of the reducer can be reduced, and the reducer can be miniaturized.
Description
Technical field
The utility model relates to technical field of bearings, is particularly useful for the outer ring of a kind of micro-reducer of micro-reducer 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 outer ring links to each other with the reducing gear housing, the inner ring whole speed reducer that constitutes that links to each other with speed reducer output shaft.This speed reducer existing problems:
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 utility model provides the outer ring 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 outer ring of existing micro-reducer.It can solve bearing capacity, the rotating speed problem of speed reducer, promptly 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 utility model adopts following technological scheme:
A kind of micro-reducer is with the outer ring of the special-shaped crossed roller bearing of integrated type, and the special-shaped interior end of bearing outer ring that intersects roller of said integrated type is provided with reducing gear, and the other end is provided with bearing inner race in the bearing outer ring; The raceway corresponding part of bearing outer ring is provided with at least one plunger hole radially; Be provided with the plunger of shutoff roller and spacing block in the said plunger hole; The spring pin and the plunger that are provided with in the said bearing outer ring end face upper spring pin-and-hole connect and compose one.
A kind of micro-reducer is with the outer ring of the special-shaped crossed roller bearing of integrated type, and said bearing outer ring is an elongate structure, and bearing outer ring is the housing of speed reducer simultaneously; The length of said bearing outer ring comprises length and the length of bearing inner race of the housing of speed reducer.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
A kind of micro-reducer is with the outer ring of the special-shaped crossed roller bearing of integrated type, owing to adopt the big integrated type crossed roller bearing of boundary dimension, the bearing outside lengthening has substituted original reducer shell.Have the Bearing Installation space and increase, can increase the roller size, increase the rated load of bearing, improve the bearing capacity and the limit speed of whole speed reducer, strengthen bearing rigidity and intensity.And can make reducing gear be installed in the overall dimensions that bearing inside has reduced speed reducer effectively, make the speed reducer miniaturization.
Description of drawings
Fig. 1 is the structural representation of micro-reducer with the special-shaped crossed roller bearing of integrated type;
Among the figure: bearing outer ring 1, bearing inner race 2, roller 3, plunger 4, spacing block 5, plunger hole 6, spring pin 7, inner ring connection screw thread hole 8, outer ring connection screw thread hole 9, spring pin hole 10, reducing gear installation position J.
Embodiment
Below in conjunction with accompanying drawing and instance the utility model is described further.
As shown in Figure 1: a kind of micro-reducer is with the outer ring of the special-shaped crossed roller bearing of integrated type, and said bearing outer ring 1 is an elongate structure, and the length of said bearing outer ring comprises length and the length of bearing inner race 2 of the housing of speed reducer; Said bearing outer ring also is the housing of speed reducer.
The special-shaped bearing outer ring 1 interior end that intersects roller of said integrated type is provided with reducing gear, and the other end is provided with bearing inner race 2 in the bearing outer ring 1; The raceway corresponding part of bearing outer ring 1 is provided with at least one plunger hole 6 radially; Be provided with the plunger 4 of shutoff roller 3 and spacing block 5 in the said plunger hole 6; The spring pin 7 that is provided with in the said bearing outer ring 1 end face upper spring pin-and-hole 10 connects 4 with plunger and connects the formation one.
During use, this micro-reducer substitutes existing outer ring or inner ring separated type crossed roller bearing and reducer shell with the special-shaped crossed roller bearing of integrated type.This integrated type crossed roller bearing outer ring lengthening; And according to the design of the shell dimension of original speed reducer; Originally the reducing gear that is installed in the housing is installed in the bearing outer ring, and bearing enclose all adopts integral design, opens a plunger hole at bearing outer ring; The rolling element of bearing---roller and spacing block are loaded in the bearing through plunger is empty
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.The bearing inner race exterior edge face increases the tapped hole that is used to connect other rotating mechanism.Owing to increased the size of bearing, can improve the bearing capacity of bearing, can improve the rigidity and the intensity of 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.
