Abstract
The invention relates to an angular contact ball bearing of an integrated planet gear speed reduction device. The angular contact ball bearing comprises an input shaft, inner rings, rolling bodies, holders, outer rings, an outer ring sun gear, a planet gear, an input shaft sun gear, a planet carrier and screws. The inner rings and the outer rings of two bearings are each provided with a small groove. The grooves are matched to form a small cavity. The rolling bodies and the holders are arranged in the cavity. The axial width of the outer rings of the two bearings is larger than that of the inner rings of the two bearings. The outer rings and the inner rings form a stepped structure. The outer rings of the two bearings are connected to form a chamber through the screws. A gear called the outer ring sun gear is arranged on portion, on the outer ring of one bearing, of the inner wall of the chamber. The input shaft is in interference fit with the inner ring of one gear. A gear called the input shaft sun gear is arranged at the end, extending into the chamber, of the input shaft. The planet gear is arranged between the two sun gears and supported by the planet carrier. The planet carrier, also called an output shaft, is in interference with the inner ring of the other bearing.
Description
Technical field
The present invention relates to angular contact bearing, especially relate to a kind of angular contact ball bearing of integrated planet wheel speed reducer.
Background technique
Train retarder has following feature with it: can realize transmission along separate routes; Larger velocity ratio can be obtained; Gear can be realized; The transmission that commutates can be realized; Can be used as the decomposition and synthesis of motion, make it use ground widely at mechanical system deceleration part, particularly take motor reducer in private, major part is all slowed down with planet wheel decelerator.But add an independently speed reducer at machine internal, this causes the raising of machine cost, the complexity of machine internal structure undoubtedly and brings the constant of installation.If there is the bearing means of a set of integrated deceleration system, when not changing the arrangements for speed regulation of the original mechanical structure of machine or non-additional external, the part only changing machine intimate just can reach the target of governing speed, this by give we machine down part manufacture and design the larger cost of saving, moreover, while improving machine compactness, reduce the installation cost of whole mechanical system, what allow complicated mechanical system become is simple.The present invention, in order to realize this goal, is integrated in Bearing inner planet wheel deceleration system, the mechanical structure of two bearings is made a little and changes, and makes they and planet wheel decelerator realize collaborative work preferably.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of angular contact ball bearing of integrated planet wheel speed reducer.
In order to effectively realize function as above, the present invention realizes as follows: this device is mainly by input shaft, and inner ring, rolling element, retainer, outer ring, outer ring sun gear, planet wheel, input shaft sun gear, planet carrier, screw forms.Its internal structure is: the inner ring of two bearings and outer ring have little groove, coordinates formation little cavity between them, and rolling element and retainer are arranged on the inside; Two bearing outer ring axial widths are wider than inner ring, and become step-like configuration, and be connected by screw formation chamber between two bearing outer rings, one of them bearing outer ring chamber inner wall is provided with gear, is called outer ring sun gear; Input shaft and one of them inner ring gear interference fit, and one that stretches into the input shaft of chamber is provided with gear, is called input shaft sun gear; Planet wheel is arranged between two sun gears, and is supported by planet carrier, planet carrier and another one bearing inner race interference fit, also claims planet carrier to be output shaft.
When input shaft input motion state, motion state is passed to planet carrier by planet wheel and outer ring sun gear by input shaft sun gear, serves the effect of deceleration, and planet carrier is also known as output shaft, and the motion state required for final exports by output shaft.
The good effect of the angular contact ball bearing of a kind of integrated planet wheel speed reducer of the present invention is: planet wheel deceleration system is integrated in Bearing inner, the mechanical structure of two bearings is made a little and changes, make they and planet wheel decelerator realize collaborative work preferably.This device has compact structure, it is easy to assembly to manufacture and have the advantages that to realize compared with big speed ratio, and therefore, it is higher and require to have in the mechanical system of larger velocity ratio that this device is mainly used in the requirement of spaces compact degree.
Fig. 1 is the internal structure principle schematic of the angular contact ball bearing of a kind of integrated planet wheel speed reducer of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in more detail.
In FIG, the angular contact ball bearing of a kind of integrated planet wheel speed reducer of the present invention, this device is mainly made up of input shaft 1, inner ring 2, rolling element 3, retainer 4, outer ring 5, outer ring sun gear 6, planet wheel 7, input shaft sun gear 8, planet carrier 9, screw 10.Its internal structure is: inner ring 2 and the outer ring 5 of two bearings have little groove, coordinates formation little cavity between them, and rolling element 3 and retainer 4 are arranged on the inside; Two bearing outer ring 5 axial widths are wider than inner ring 2, and become step-like configuration, and be connected to form a chamber by screw 10 between two bearing outer rings 5, one of them bearing outer ring 5 chamber inner wall is provided with gear, is called outer ring sun gear 6; Input shaft 1 and one of them inner ring gear 2 interference fit, and one that stretches into the input shaft 1 of chamber is provided with gear, is called input shaft sun gear 8; Planet wheel 7 is arranged between two sun gears, and is supported by planet carrier 9, and planet carrier 9 and another one bearing inner race 2 interference fit, also claim planet carrier 9 to be output shaft.
When input shaft 1 input motion state, motion state is passed to planet carrier 9 by planet wheel 7 and outer ring sun gear 6 by input shaft sun gear 8, serves the effect of deceleration, and planet carrier 9 is also known as output shaft, and the motion state required for final exports by output shaft.
This device is integrated in Bearing inner planet wheel deceleration system, the mechanical structure of two bearings is made a little and changes, and makes they and planet wheel decelerator realize collaborative work preferably.This device has compact structure, it is easy to assembly to manufacture and have the advantages that to realize compared with big speed ratio, and therefore, it is higher and require to have in the mechanical system of larger velocity ratio that this device is mainly used in the requirement of spaces compact degree.
