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) divergence 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.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 present invention provides 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, integral rigidity, the rotating speed problem of speed reducer.Promptly improve bearing capacity, the integral rigidity of speed reducer effectively, improve the rotating speed of speed reducer; Make complete machine convenient disassembly in using maintenance; Alleviate the weight of speed reducer.
For realizing aforesaid goal of the invention, the present invention adopts following technological scheme:
A kind of micro-reducer is with the special-shaped crossed roller bearing of integrated type, and said bearing is a monolithic construction, comprising: bearing outer ring 1, bearing inner race 2, roller 3, plunger 4, spacing block 5, spring pin 7.State the special-shaped bearing outer ring 1 interior end that intersects roller of integrated type and be provided with reducing gear, the other end is provided with the inner ring 2 of bearing in the bearing outer ring 1; The raceway corresponding part of the raceway of bearing inner race 2 and bearing outer ring 1 is provided with and is at least a 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 and the plunger that are provided with in the said bearing outer ring 1 end face upper spring pin-and-hole connect and compose one.
A kind of micro-reducer is with the special-shaped crossed roller bearing of integrated type, and said bearing outer ring also is the housing of speed reducer, and said bearing outer ring 1 is an elongate structure, and the length of said bearing outer ring comprises the length of the shell dimension and the bearing inner race 2 of speed reducer.
A kind of micro-reducer is with the special-shaped crossed roller bearing of integrated type, and said plunger is provided with and the corresponding perforation of bearing outer ring 1 end face upper spring pin-and-hole inner spring pin.
A kind of micro-reducer is with the special-shaped crossed roller bearing of integrated type, and said bearing inner race 2 exterior edge faces are provided with the tapped hole that connects rotating mechanism.
A kind of micro-reducer is with the special-shaped crossed roller bearing of integrated type, the plastic construction of said spacing block self lubricity.
Because adopt aforesaid technological scheme, the present invention has following superiority:
A kind of micro-reducer is with the special-shaped crossed roller bearing of integrated type, because the integrated type crossed roller bearing that adopts boundary dimension to strengthen, the bearing outside lengthening has substituted original reducer shell.The boundary dimension of bearing increases, and can load large size roller, has increased the rated load of bearing, improves the bearing capacity and the rotating speed of whole speed reducer, strengthens bearing rigidity and intensity.Reducing gear is installed in the overall dimensions that bearing inside has reduced speed reducer effectively on the other hand, makes the speed reducer miniaturization.Alleviated the weight of speed reducer.

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, outer ring external diameter plunger hole 6, spring pin 7, inner ring connection screw thread hole 8, outer ring connection screw thread hole 9, cycle surface spring pin hole 10, reducing gear installation position J.
Embodiment
Below in conjunction with accompanying drawing and instance the present invention is described further.
As shown in Figure 1: a kind of micro-reducer is with the special-shaped crossed roller bearing of integrated type, and said bearing is a monolithic construction, comprising: the special-shaped crossed roller bearing of integrated type outer ring 1; The special-shaped crossed roller bearing inner ring 2 of integrated type, roller 3, plunger 4; Spacing block 5; The special-shaped crossed roller bearing of integrated type outer ring external diameter plunger hole 6, spring pin 7, the special-shaped crossed roller bearing inner ring of integrated type connection screw thread hole 8; The special-shaped crossed roller bearing of integrated type outer ring connection screw thread hole 9, the special-shaped crossed roller bearing cycle surface of integrated type spring pin hole 10.An end is provided with reducing gear in the special-shaped crossed roller bearing of the said integrated type outer ring 1, and the other end is provided with bearing inner race 2 in the bearing outer ring 1; The raceway corresponding part of the raceway of bearing inner race 2 and bearing outer ring 1 is provided with and is at least a plunger hole 6 radially; Be provided with the plunger of shutoff roller and spacing block in the said plunger hole 6; The spring pin and the plunger that are provided with in the said bearing outer ring 1 end face upper spring pin-and-hole connect and compose one.
Said bearing outer ring is the housing of speed reducer, and said bearing outer ring 1 is an elongate structure, and the length of said bearing outer ring comprises the length of the shell dimension and the bearing inner race 2 of speed reducer.
