Abstract
The utility model provides a double-groove conjoined angular contact ball bearing, which comprises a bearing outer ring, two rows of bearing steel balls, two bearing inner rings, two retaining frames, one inner ring lining and an adjusting washer., a circular rollaway nest is respectively arranged at the two ends of the bearing outer ring, corresponding to the rollaway nest of the two bearing inner rings and forms contact angles with the rollaway nest of the two bearing inner rings; the inner ring lining, a shaft shoulder and the adjusting washer lock the bearing inner rings; the shaft, a processing washer and a processing screw make the utility model a removable conjoined bearing. The utility model adopts the conjoined bearing outer ring, which can improve the requirements on the form and position of the co-axiality and the verticality of the shaft system, so that the bearing has high accuracy and the service life can be prolonged; and the processing difficulty can not be increased. The utility model also has the advantages of simple structure, convenient assembly and adjustable axial preload, etc.
Description
Technical field
The utility model relates to a kind of entad angular contact ball bearing, is specifically related to a kind of double groove conjoined angular contact ball bearing, is specially adapted to highi degree of accuracy, has high-revolving inertia type instrument, as dynamically tuned gyro, DTG.Belong to mechanical manufacturing field.
Background technique
In the prior art, have high-revolving high-precision meter rotary axis and generally adopt the angular contact bearing of paired mounting to realize, because the part that axle system forms is more, it exists assembling complicated, and to the bigger problem of its precision influence.Promptly because the foozle of matrix and the foozle of each part that axle system forms are installed by axle system, after combining, the cumulative error that forms makes the combination precise decreasing of axle system, make the rotatingshaft position instability of axle system, it is not steady to cause whole rotation system to rotate, produce vibrations, thereby accuracy of instrument is descended, and can shorten its working life.The disclosed ZL200520033268.1 of Chinese patent " the moving integrated drive shaft assembly of mode gyroscope ", in order to simplify the mechanical structure of drive shaft assembly, improve the stability of reference axis, change inner ring into overall structure, but must increase difficulty of processing like this, the up-to-standard rate of product is difficult to be guaranteed; Simultaneously, also there is the deficiency of adjusting inconvenience.
The model utility content
At the prior art above shortcomings, the purpose of this utility model is to provide a kind of precision height, and is simple in structure; Simultaneously, do not increase the double groove conjoined angular contact ball bearing of difficulty of processing.
The purpose of this utility model is achieved in that a kind of double groove conjoined angular contact ball bearing, it is characterized in that comprising a bearing outer ring, two row bearing steel balls, two bearing inner races, two retainers, an inner ring bushing and an adjustment packing ring, at the two ends of bearing outer ring a ring raceway is arranged respectively, corresponding with the raceway of two bearing inner races, and form wrapping angle; Inner ring bushing, the shaft shoulder and adjustment packing ring pin bearing inner race; Axle, technology packing ring and technology screw are formed removable piece bearing with it.
Described bearing outer ring radially is provided with the through hole of the axial pre-load that is used for test bearing.
Compared to existing technology, the utlity model has following advantage:
1, adopts the bearing outer ring of disjunctor, can improve morpheme requirements such as a coaxality of system, perpendicularity, make bearing have high precision, adopt two angular contact bearings to realize that the precision of axle system is high, thereby can prolong its working life; The routine techniques that is processed as owing to integral type outer race can not increase difficulty of processing yet.
2, reducing axle is component part kind and quantity, simplifies the structure, and has reduced assembling difficulty; Bearing of the present utility model is removable, because of the part kind is few, mounts and dismounts all very convenient.
3, at bearing outer ring radial design through hole, can be by the size of experience sensation or dynamometry instrumentation formula bearing axial pre-load, making whole axle is to obtain more required preload at last.
4, the maximum characteristics of the utility model are that preload can adjust as required, and easy to adjust accurate, pass through radially center through hole φ of bearing outer ring earlier, the size of the axial pre-load of sensation and the formula of survey bearing, reach by the thickness size of adjusting packing ring, this technology belongs to domestic initiation again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, bearing outer ring 2, bearing steel ball 3, bearing inner race 4, retainer 5, inner ring bushing 6, axle 7, adjust packing ring 8, technology packing ring 9, technology screw.
Embodiment
As shown in Figure 1, a kind of double groove conjoined angular contact ball bearing, comprise that a bearing outer ring 1, two row bearing steel balls 2, two bearing inner races 3, two retainers 4, inner ring bushing 5 and one adjust packing ring 7, at the two ends of bearing outer ring 1 ring raceway is arranged respectively, corresponding with the raceway of two bearing inner races, and form wrapping angle α; Inner ring bushing 5, axle 6 shoulders and adjustment packing ring 7 pin bearing inner race 3, and the big I of the required preload of bearing reaches by the thickness size of adjusting packing ring 7.Axle 6, technology packing ring 8 and technology screw 9 are formed removable piece bearing with it.Bearing outer ring radially central authorities has a through hole φ, is used to feel or the size of the axial pre-load of test bearing.
The material of retainer 4 can be a metal or nonmetal as required.Axle 6 can be used as live axle or the technology axle uses, dismounting or redesign as required.
The zanjon conjoined angular contact ball bearing that the utility model is related, its internal diameter (bearing inner race bore dia), external diameter (bearing outer ring outside diameter) and steel ball size and wrapping angle all adopt meet various serial model No. bearings among the GB/T292-1994 " radial bearing angular contact ball bearing boundary dimension " in, outside dimension, steel ball size and contact angle requirement, it is the bearing inner race of this conjoined angular contact ball bearing, the bearing inner race of steel ball and retainer and GB/T292-1994 angular contact ball bearing, steel ball and retainer have structure interchangeability, belong to general part, use very convenient.
The utility model is a kind of highi degree of accuracy piece bearing, and main purpose is in order to improve the service precision of bearing, and simplified structure is simplified technology.The utility model has adopted single outer ring, two inner rings, double-row bearing steel ball structure.The bearing enclose diameter meets the GB/T292-1994 requirement, and length can design and produce according to usage requirement, and retainer can be according to actual conditions as metal or nonmetal.Be mainly used in the high-revolving inertia type instrument of highi degree of accuracy, be specially adapted to have high-revolving dynamically tuned gyro, DTG, can improve its precision and run stability, reduce vibrations.
