Description
Technical field
The device for preventing power transmission shaft from axial moving occur is the utility model is related to, more particularly to self-aligning roller bearing assembling is used
There is the device of axial moving in power transmission shaft.
Background technology
Self-aligning roller bearing can not carry larger axial load in itself, when operating mode is severe or the working time is longer,
With bearing fit position axial moving can occur for axle, cause axle to be worn with bearing, influence stabilization of equipment performance, can be led when serious
Device damage is caused, is used for ensureing that the work of equipment is steady so needing a kind of special device for preventing power transmission shaft from axial moving occur
Fixed and equipment safety.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, and axle and bearing fit position can be avoided by providing one kind
Put and the axial moving, working stability for ensureing equipment, equipment safety, compact-sized occurs, make simple, easy to maintenance prevents axle
To moving device.
It is of the present utility model to prevent axial moving device, including centre is provided with through hole and outside has cylindrical boss
Lock sleeve, described lock sleeve are sleeved on power transmission shaft by intermediate throughholes and are fixedly linked with power transmission shaft, for transmitting radially
The inner ring suit of the self-aligning thrust roller bearing of rotation is fixed in the cylindrical boss of described lock sleeve, and described thrust is adjusted
The outer ring setting-in of heart roller bearing is fixed in the groove of bearing supporting frame, and described bearing supporting frame is fixed on bearing block.
The advantages of the utility model：1st, it is simple in construction, convenient manufacture；2nd, it is safe and reliable, it is durable lasting；3 costs are relatively low, can
Seriation is differently formed according to power transmission shaft size；4th, it is easy to maintenance, securely and reliably.
Brief description of the drawings
Fig. 1 is the side view of the present utility model for preventing axial moving device；
Fig. 2 is the A-A schematic cross-sectional views of the device shown in Fig. 1；
Fig. 3 is the stereogram of the device shown in Fig. 1.
Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in drawings, it is of the present utility model to prevent axial moving device, including centre is provided with through hole and outside has
The lock sleeve 2 of cylindrical boss, described lock sleeve 2 be sleeved on by intermediate throughholes on power transmission shaft 6 and with the stationary phase of power transmission shaft 6
Even, the inner ring suit of the self-aligning thrust roller bearing 3 for transmitting radial rotating be fixed on described lock sleeve 2 cylindrical shape it is convex
On platform, the outer ring setting-in of described self-aligning thrust roller bearing 3 is fixed in the groove of bearing supporting frame 4, described bearing branch
Support 4 is fixed on bearing block 5.
Protective cover 1, described lock sleeve 2 and thrust force aligning roller are preferably fixed with described bearing supporting frame 4
Bearing 3 is arranged in protective cover 1, and described protective cover 1 is used to protect single unit system.
Preferable described protective cover 1 uses transparent material, the working condition of mechanism arrangement when being easy to the facilities for observation to operate.
Preferable described lock sleeve 2 uses ironcasting, and impact resistance is strong, and screwed hole is provided with described lock sleeve,
Described lock sleeve is fixedly linked by the jackscrew through screwed hole with power transmission shaft.Simultaneously can also conveniently dismounting thrust force aligning rolling
Sub- bearing, lock sleeve are provided with reinforcement, make structure more solid and reliable.
Described self-aligning thrust roller bearing 3, which belongs to standard component, can form series, and buying is convenient, has automatic aligning
Can, axially and radially load can be born simultaneously, and the flexure to nonconcentricity and axle is insensitive.
Preferable described bearing supporting frame 4 uses ironcasting, and impact resistance is strong, is provided with described bearing supporting frame
Screwed hole, described bearing supporting frame are fixedly linked by the bolt through screwed hole with bearing block.Thrust can conveniently be dismantled
Self-aligning roller bearing.
The installation method of the present apparatus is：
The suit of lock sleeve 2 is first fixed on power transmission shaft 6 to, integral device operation suspension then by thrust force aligning roller
The inner ring of bearing 3 is enclosed on lock sleeve, the outer ring of self-aligning thrust roller bearing 3 is inlaid in the groove of bearing supporting frame, axle
Hold support frame to be fixed on bearing block 5, bearing supporting frame and bearing block 5 are fixed and pass through power transmission shaft 6, then installation protection
Cover, finally adjusts axial gap, the base of fixed bearing block 5, starting device restarts work.
