Abstract
The utility model relates to an integrated planet wheel decelerator's deep groove ball bearing. The device includes input shaft, inner circle, rolling element, holder, outer lane, outer lane sun gear, planet wheel, input shaft sun gear, planet carrier, screw. Little recess has been opened respectively to the inner circle and the outer lane of two bearings, and the cooperation forms a little cavity between them, and rolling element and holder installation are inside, two bearing inner race axial width ratio inner circles are wide, and become the echelonment structure, form a cavity through the screw connection between two bearing inner race, and the gear is installed to one of them bearing inner race cavity inner wall, is called the outer lane sun gear, input shaft and one of them gear inner circle interference fit just stretch into one end of the input shaft of cavity and install the gear, are called the input shaft sun gear, the planet wheel is installed between two sun gears to by the planet carrier support, planet carrier and another one bearing inner race interference fit call also that the planet carrier is the output shaft.
Description
Technical field
The utility model relates to deep groove ball bearing, especially relates to a kind of deep groove 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 utility model, 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.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of deep groove ball bearing of integrated planet wheel speed reducer.
In order to effectively realize function as above, the utility model 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.
During 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 final required motion state of output shaft exports.
The good effect of the deep groove ball bearing of a kind of integrated planetary reduction gear described in the utility model 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.
Accompanying drawing explanation
Fig. 1 is the internal structure principle schematic of the deep groove ball bearing of a kind of integrated planet wheel speed reducer of the utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
In FIG, the deep groove ball bearing of a kind of integrated planet wheel speed reducer of the utility model, 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.
