Abstract
The utility model relates to the technical field of bearings, and discloses a device for connecting an inner ring and an outer ring of an integrated abnormally-shaped intercrossed roller bearing for a micro speed reducer. The device comprises bearing outer rings (1) integrated with the speed reducer, bearing inner rings (2), plungers (4) and spring pins (7), wherein the plungers which are arranged in radial plunger holes (6) of the bearing outer rings (1) integrated with the speed reducer and used for plugging rollers and isolation blocks are combined with the bearing inner rings (2) to form a whole; and the plungers in the radial plunger holes (6) are matched with the spring pins arranged in spring pin holes on the end faces of the bearing outer rings (1). The rated load of the bearing can be increased, the bearing capacity and the rotating speed of the whole speed reducer can be increased, and the rigidity and the strength of the bearing are improved. The size of the whole speed reducer can be effectively reduced, so that the speed reducer is minimized.
Description
Technical field
The utility model relates to technical field of bearings, is particularly useful for the Internal and external cycle connection set of a kind of micro-reducer of micro-reducer with the special-shaped crossed roller bearing of integrated type.
Background technique
At present, 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.Bearing Installation is in enclosure interior, and the restriction in enclosure interior space uses little outer ring (or inner ring) the separated type crossed roller bearing bearing capacity of boundary dimension low, and pedestal also is not easy to the installation and maintenance dismounting.Select for use the little bearing of boundary dimension on rotating speed, also to limit the rotating speed of speed reducer on the other hand, can not give play to the maximum performance of reducing gear.
Summary of the invention
In order to overcome the deficiency that existing technology exists, the utility model provides the Internal and external cycle connection set 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, 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 Internal and external cycle connection set of the special-shaped crossed roller bearing of integrated type; Comprise: with bearing outer ring, bearing inner race, plunger and the spring pin of speed reducer disjunctor; The shutoff roller that is provided with in the said bearing outer ring radial column consent and the plunger of spacing block with the speed reducer disjunctor; Combine to constitute one with bearing inner race, the spring pin of the setting formation that is connected in the plunger in the radial column consent and the bearing outer ring end face upper spring pin-and-hole.
A kind of micro-reducer is with the Internal and external cycle connection set of the special-shaped crossed roller bearing of integrated type, and said plunger hole is arranged on the corresponding raceway place of bearing outer ring.
A kind of micro-reducer is with the Internal and external cycle connection set of the special-shaped crossed roller bearing of integrated type, and said plunger is provided with and the corresponding perforation of bearing outer ring end face upper spring pin-and-hole inner spring pin.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
A kind of micro-reducer is with the Internal and external cycle connection set of the special-shaped crossed roller bearing of integrated type, owing to adopt the integrated type crossed roller bearing of big model, the bearing outside lengthening has substituted original reducer shell.The Bearing Installation space increases on the one hand, can increase the roller size, has increased the rated load of bearing, has improved 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.
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, outer ring radial column consent 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 utility model is described further.
As shown in Figure 1: a kind of micro-reducer is with the Internal and external cycle connection set of the special-shaped crossed roller bearing of integrated type; Comprise: with bearing outer ring 1, bearing inner race 2, plunger and the spring pin 5 of speed reducer disjunctor; The shutoff roller that is provided with in the said bearing outer ring 1 radial column consent 6 and the plunger of spacing block with the speed reducer disjunctor; Combine to constitute one with bearing inner race 2, the spring pin of the setting formation that is connected in the plunger in the radial column consent 6 and the bearing outer ring 1 end face upper spring pin-and-hole.Said plunger hole 6 is arranged on the raceway place of bearing outer ring 1 correspondence.Said plunger is provided with and the corresponding perforation of bearing outer ring 1 end face upper spring pin-and-hole inner spring pin.
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 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.
