Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of bearing play automatic regulating apparatus.
Background technique
The application right and wrong that are applied in mechanical field of bearing are usually seen, need to relatively rotate between central shaft and pedestal or other mechanism, central shaft frictional force when rotating is little, rotation is more flexible in order to make, operated by rotary motion has bearing between central shaft and pedestal (or other mechanism) in relative rotation, during installation, the outer ring of bearing contacts with the internal surface of bearing support, the outer ring of bearing contacts with central shaft, install after the bearing, sliding friction between central shaft and the pedestal is converted into rolling friction, and surface friction drag significantly reduces; But nonetheless, when central shaft rotates, also can cause the abrasion of bearing and make and have the gap between the bearing, and have influence on the accuracy of mechanism's operation, because the existence in gap also can produce noise; Solve the gap to the influence that mechanism caused, main method can only be the bearing that more renews now, the cost height of maintenance.
Summary of the invention
The purpose of this utility model is to provide the bearing play automatic regulating apparatus, and after the bearing abrasion, this device is the adjusting play automatically, improves the accuracy of mechanism's operation, improves working life, and operational noise is little.
The utility model is achieved through the following technical solutions:
A kind of bearing play automatic regulating apparatus, Bearing Installation is in the mounting hole of bearing support, central shaft is installed in the bearing, described bearing is a spring bearing, between bearing inner race and the central shaft, between bearing outer ring and the bearing support mounting hole, both are provided with two wedge-shaped sleeves that match in one of them at least, and the wedge shape inclined-plane of these two wedge-shaped sleeves is contact matching relatively also; Two axially outer ends of these two wedge-shaped sleeves are by axial limiting, and wherein have at least the axially outer end of a wedge-shaped sleeve to compress by elastic component and spacing; On two wedge-shaped sleeves, be equipped with the opening that connects to another axle head from an one axle head.
In the utility model, one of them axially outer end of two wedge-shaped sleeves is compressed by elastic component that (another axially outer end can be spacing by the step on the central shaft, perhaps undertaken spacing by alternate manner), in the central shaft rotation process, spring bearing produces wearing and tearing, after wearing and tearing, between spring bearing and the bearing support or and central shaft between can produce the gap, at this moment, under the effect of elastic component, two wedge-shaped sleeves mutually near and remedy the gap that wearing and tearing produce, after two wedge-shaped sleeves were adjusted automatically, its gap can be adjusted into zero substantially, after bearing wear, two wedge-shaped sleeves are adjusted once more, in the utility model, after bearing wear, within the specific limits, two wedge-shaped sleeves can be adjusted the bearing play automatically, need not change bearing, also need not manually adjust, easy to use, more reliable when mechanism moves, noise is little; When wedge-shaped sleeve was set, two wedge-shaped sleeves can be located between bearing inner race and the central shaft, also can be located between bearing outer ring and the bearing support mounting hole.
Further structure of the present utility model is:
Described wedge-shaped sleeve is located between described bearing inner race and the described central shaft, and at this moment, a side excircle of described wedge-shaped sleeve is provided with screw thread.During dismounting, after the screw-thread fit on a thread bush and the wedge-shaped sleeve, can easily wedge-shaped sleeve be transferred to, thereby spring bearing is got loose, the easier replacing of bearing.
Perhaps, described wedge-shaped sleeve is located between described bearing outer ring and the described bearing support, and at this moment, the part inner circumference of described wedge-shaped sleeve is provided with screw thread.
Described elastic component is a belleville spring, and a side of this belleville spring is pressed on the axially outer end of described wedge-shaped sleeve, and limited of opposite side is spacing, and bounding means is fixed on central shaft or the bearing support by screw thread.This belleville spring is spacing by nut first, and opposite side is pressed on one of them wedge-shaped sleeve axially outer end, and two wedge-shaped sleeves are pushed against mutually, the gap that can adjust bearing wear at any time and produced.By swivel nut, can set pretightening force, long between in use, when the bearing wear amount is big, also can adjust once more pretightening force by nut.Further, described belleville spring is one or more pieces, when being that two its dish hand-deliver forks when above are oppositely arranged.
Position of mounting hole is provided with end cap described central shaft, spring bearing is covered on the described bearing support.This end cap plays dustproof, protective action to structures such as bearings.
When the utility model applied to the structure of the slow-speed of revolution, little corner or light load, its advantage was more obvious.
