Abstract
Belonging to the technical field of bearing structures, the utility model in particular relates to a control surface bearing structure. A control surface rotation shaft is formed by connecting a rotation shaft and a stepped shaft in sleeve joint by connecting bolts. A shell is disposed outside the stepped shaft, a bearing mounting hole is disposed on the shell, and a bearing is mounted in the bearing installation hole. The control surface and the stepped shaft are connected through stepped shaft connecting holes. The utility model has the beneficial effects that: 1. the stepped holes are adopted to replace a bearing mounting socket; 2. the stepped shaft involved in the utility model plays the role of bearing protection, bearing watertightness, control surface installation bracket and control surface rotation shaft; 3. during installation of the bearing involved in the utility model, on the bearing installation stepped holes, the shaft shoulder compresses the bearing outer ring, and on the stepped shaft, the shaft shoulder compresses the bearing inner ring, and the bearing achieves two-way compression; and 4. in the utility model, the rotation shaft cooperates with the stepped shaft, and cooperation among the connecting bolts, the rotation shaft and the stepped shaft 7 adopts H/f cooperation, thus eliminating the gap caused by connection.
Description
Technical field
The utility model belongs to the bearing structure technical field, is specifically related to a kind of rudder face bearing structure.
Background technique
Present various shaft bearing is installed most modes that adopt bearing sleeves and add protecting cover and is installed, and this installation method is widely used in the place of light load easy disassembly, such as the installation and removal of casing inner bearing.But for the operation of carrying out the bearing installation and removal at body rudder face axle, all be not subjected to the restriction of installing space, use bearing housing to be equivalent to increase a mating parts, must have tolerance and have (this tolerance grade directly affects shaft run-out) in the course of working of bearing housing, will form the accumulation of tolerance in the process of installing,, for body rudder face turning shaft structure and position characteristics, design a kind of bearing installation method and structure and address the above problem.
Summary of the invention
The utility model is in order to overcome above-mentioned defect, and purpose is to provide a kind of installation method connecting structure simple, and the rudder face bearing structure of easily implementing.
In order to achieve the above object, the utility model adopts following technological scheme:
A kind of rudder face bearing structure, the rudder face rotating shaft is socketed by rotating shaft and multidiameter shaft, and with connecting bolt, connects to form, and multidiameter shaft is outside equipped with housing;
On described housing, bearing mounting hole is arranged, bearing is arranged in bearing mounting hole;
Rudder face is connected by the multidiameter shaft attachment hole with multidiameter shaft.
Described multidiameter shaft is equipped with seal ring.
It comprises dust cover, seal groove, rudder face lug-mounted, rotating shaft described multidiameter shaft.
Be provided with one or an above attachment hole in rotating shaft.
Described attachment hole is bottom outlet.
Described connecting bolt is hinge bolt.
The quantity of multidiameter shaft attachment hole is 5.
At described housing, bearing is housed.
For fear of the tolerance stack that produces under a plurality of operations such as processing, installation at bearing sleeve and reduce part in rotation process, the bearing sleeve machining accuracy, on the impact that shaft run-out produces, designs bearing mounting hole on the body of cabin.
The beneficial effects of the utility model:
1, shoulder hole of the present utility model, install bearing sleeve to replace bearing;
2, the utility model multidiameter shaft is born the effect of protection, bearing watertight, rudder face mounting bracket and rudder face rotating shaft.
When 3, the utility model bearing was installed, bearing was installed shaft shoulder compression axis bearing outer-ring on shoulder hole, and on multidiameter shaft, the shaft shoulder compresses bearing inner race, bearing Bidirectional compacting.
4, the utility model rotating shaft coordinates with multidiameter shaft, connecting bolt coordinates with rotating shaft and 7 of multidiameter shafts and all adopt H/f to coordinate, and eliminates the gap that causes because of connection.

Embodiment
Be elaborated below in conjunction with accompanying drawing 1,2,3,4 pairs of the utility model:
A kind of rudder face bearing structure, the rudder face rotating shaft is socketed by rotating shaft 4 and multidiameter shaft 7, and with connecting bolt 5, connects to form, and multidiameter shaft 7 is outside equipped with housing 2;
On described housing 2, bearing mounting hole 14 is arranged, bearing 3 is arranged in bearing mounting hole 14;
Described multidiameter shaft 7 is equipped with seal ring 6.
It comprises dust cover 8, seal groove 9, rudder face lug-mounted 10, rotating shaft 11 described multidiameter shaft 7.
Be provided with one or an above attachment hole 12 in rotating shaft 11.
Described attachment hole 12 is bottom outlet.
Described connecting bolt 5 is hinge bolt.
The quantity of multidiameter shaft attachment hole 13 is 5.
At described housing 2, bearing is housed.
After rotating shaft 4 was socketed with multidiameter shaft 7, with attachment hole 12 hinge precision preparation holes (as precision in Fig. 3, being H), H/f coordinated elimination because of the vibration that joint gap forms, and avoids causing the control surface deflection error.
Bearing removal method: with bearing installation method inverted order, can realize bearing dismantling.
This kind bearing installation method connecting structure is simple, and easily implements, and this invention installation of multiple bearing in certain model is repeatedly used, and all can meet usage requirement.The present invention connects form structure by changing multidiameter shaft 7, and this can be widely used in the development of construction project.
