Abstract
The utility model is related to a kind of bearing compressing structures, including bearing, pressing plate, backing plate, gear shaft is mounted on by bearing on casing, it is arranged on outer race fluted, pressing plate one end is mounted on by screw on casing, the other end is stuck in the groove of outer race, and backing plate is provided between the pressing plate and casing, and the thickness of the backing plate is the difference of the distance between casing mounting surface and outer race groove surface and crush.The utility model can control size of the bearing plate to outer race pressing force, to improve bearing working reliability.
Description
Technical field
The utility model is related to a kind of bearing compressing structures.
Background technology
In Helicopter Transmission System, there are typical structure as shown in Figure 1, in gear shaft and casing component, outer race
It is equipped with groove, and is compressed by bolt, self-locking nut structure using bearing plate, makes outer race axial retention, this kind is only
Flowing mode is simple in structure, and using convenience, but to prevent bearing axial float, it is accurate to ensure to remain to be located at when it bears service load
Operating position need to apply certain pretightning force by bearing plate to outer race, and such compressing structure is unable to control bearing plate
To the size of outer race pressing force, reliability is to be improved.
Invention content
The purpose of this utility model is to provide a kind of bearing compressing structure, can control bearing plate and be compressed to outer race
The size of power improves bearing working reliability.
The specific technical solution of the utility model is that bearing compressing structure includes bearing, pressing plate, backing plate, and gear shaft passes through
Bearing be mounted on casing on, be arranged on outer race it is fluted, pressing plate one end by screw be mounted on casing on, the other end is stuck in
In the groove of outer race, backing plate is provided between the pressing plate and casing, the thickness of the backing plate is casing mounting surface
Difference of the distance between the outer race groove surface with crush.
The utility model while realizing the compression of bearing, is rationally set by being provided with backing plate between pressing plate and casing
The thickness for counting pressing plate, to realize control of the bearing plate to outer race crush.The utility model can be with control shaft pressure-bearing
Plate is to the size of outer race pressing force, to improve bearing working reliability.
Description of the drawings
Fig. 1 is primitive axis pressure-bearing locking structure schematic diagram；
Fig. 2 is the structural schematic diagram of the utility model.
Specific implementation mode
As shown in Fig. 2, bearing compressing structure includes bearing 1, pressing plate 2, backing plate 3, gear shaft 4 is mounted on machine by bearing 1
On casket 5, be arranged on 1 outer shroud of bearing it is fluted, 2 one end of pressing plate by screw be mounted on casing 5 on, the other end is stuck in outside bearing 1
In the groove of ring, be provided with backing plate 3 between the pressing plate 2 and casing 5, the thickness of the backing plate 3 be 5 mounting surface of casing with
Difference of the distance between the 1 inner annular recess face of bearing with defined crush.
