Abstract
The invention provides a double-groove siamesed edge-contact spherical bearing, comprising an outer bearing ring, two arrays of bearing beads, two inner bearing rings, two support stands, an inner ring bushing, and a regulation gasket. Both ends of the outer bearing ring are respectively provided with a ring rolling channel corresponding with rolling channels of the two inner bearing rings, and form a contact angle; the inner ring bushing, a shoulder and the regulation gasket lock the inner bearing rings; the invention is assembled by a shaft, a craft gasket and craft screws into a detachable siamesed bearing. The invention adopts siamesed outer bearing rings, which can increase such size and position requirements as concentricity and perpendicularity of the shaft system, and endows the bearing with high precision, thus prolonging the service life of the bearings without increasing the working difficulty. The invention also has the advantages of simple structure, being convenient to be arranged, and adjustable axial preload and so on.
Description
Technical field
The present invention relates to a kind of entad angular contact ball bearing, be specifically related to a kind of double groove conjoined angular contact ball bearing, be specially adapted to high precision, have high-revolving inertia type instrument, as dynamically tuned gyro, DTG.Belong to mechanical manufacturing field.
Background technology
In the prior art, have high-revolving high-precision meter rotary axis and generally adopt the angular contact bearing of mounted in pairs 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 errors that forms makes the combination precise decreasing of axle system, make the rotation axis 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 serviceable life.The disclosed ZL200520033268.1 of Chinese patent " the moving integrated drive rod assembly of mode gyroscope ", in order to simplify the physical construction of drive rod assembly, improve the stability of datum axis, change inner ring into one-piece construction, but must increase difficulty of processing like this, the qualification rate of product is difficult to be guaranteed; Simultaneously, also there is the deficiency of adjusting inconvenience.
Summary of the invention
At the prior art above shortcomings, the object of the present invention is to provide a kind of precision height, simple in structure; Simultaneously, do not increase the double groove conjoined angular contact ball bearing of difficulty of processing.
The object of the present invention is achieved like this: 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 contact 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 present invention has following advantage:
1, adopts the bearing outer ring of disjunctor, can improve morpheme requirements such as a right alignment of system, verticality, make bearing have high precision, adopt two angular contact bearings to realize that the precision of axle system is high, thereby can prolong its serviceable 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 assembly difficulty; Bearing of the present invention 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 dynamometer test bearing axial pre-load, making whole axle is to obtain more required preload at last.
4, the maximum characteristics of the present invention are that preload can adjust as required, and easy to adjust accurately, by bearing outer ring center through hole φ radially, the size of the axial pre-load of sensation and test bearing reaches by the gauge of adjusting packing ring more earlier.
Description of drawings
Fig. 1 is a structural representation of the present invention.
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 contact 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 gauge 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 axial pre-load size of test bearing.
The material of retainer 4 can be a metal or nonmetal as required.Axle 6 can be used as driving shaft or the technology axle uses, dismounting or redesign as required.
Zanjon conjoined angular contact ball bearing involved in the present invention, its internal diameter (bearing inner race bore dia), external diameter (bearing outer ring outside diameter) and steel ball size and contact angle all adopt and meet GB/T292-1994 " radial bearing, angular contact ball bearing physical dimension " in various serial model No. bearings 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 present invention is a kind of high precision piece bearing, and fundamental purpose is in order to improve the service precision of bearing, and simplified structure is simplified technology.The present invention 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 request for utilization, and retainer can be according to actual conditions as metal or nonmetal.Be mainly used in the high-revolving inertia type instrument of high precision, be specially adapted to have high-revolving dynamically tuned gyro, DTG, can improve its precision and run stability, reduce vibrations.
