Description

A kind of graphite bearing provision for disengagement of shield electric machine top chock

Technical field

The utility model relates to a kind of provision for disengagement, and it is intact to relate in particular to graphite bearing a kind of simple in structure, easy to manufacture, that disassemble, can reuse, easy to use the graphite bearing provision for disengagement that has greatly improved the shield electric machine top chock of removal efficiency.

Background technology

Top chock 1 assembly of shield electric machine is a vitals (see figure 1) in the motor.In use, often in order to change the axial string quantity of graphite bearing 2 or adjustment motor, need dismounting graphite bearing 2.But in order to guarantee service precision; what adopt when graphite bearing 2 cylindrical Φ d1 and brearing bore Φ d design is interference fits; must adopt the mode that is pressed into to assemble when graphite bearing 2 is with the upper bearing (metal) assembling like this, from top chock 1, take out according to the dismounting mode of routine is very difficult so graphite bearing 2 so often can occur.Yet now in order to take out graphite bearing 2, often be to break graphite bearing 2 into pieces, graphite bearing 2 has just been scrapped like this, can not reuse, and causes waste of material, increases production cost.Therefore for fear of the waste of graphite bearing, the graphite bearing provision for disengagement that designs a kind of top chock is very important.

In addition, because graphite bearing hardness is very high, breaks graphite bearing into pieces and be not easy, need to drop into very large manpower, efficient is very low.So in order to reduce production costs, improve the removal efficiency of graphite bearing, design a kind of graphite bearing provision for disengagement of top chock, have important practical significance.

The utility model content

For the problems referred to above, it is a kind of simple in structure that main purpose of the present utility model is to provide, graphite bearing easy to manufacture, that disassemble is intact, can reuse, easy to use the graphite bearing provision for disengagement that has greatly improved the shield electric machine top chock of removal efficiency.

The utility model solves above-mentioned technical problem by following technical proposals: a kind of graphite bearing provision for disengagement of shield electric machine top chock, and described provision for disengagement comprises supporting component, rod assembly and nut;

Described supporting component comprises circular steel plate and steel pipe, has the circular hole that rod assembly enters on the steel plate, has the hole of the adjusting yoke assembly being installed for convenient on the steel pipe;

Described rod assembly comprises threaded rod I, threaded rod II, transition steel plate, two arm-ties, two blocks of crescent moon steel plates; Wherein two arm-ties are parallel is welded into " several " word shape with transition steel plate, wherein have the hole that threaded rod I vertically passes on an arm-tie, threaded rod I vertically passes on the arm-tie rear thread bar I and is provided with nut I, threaded rod II is vertically welded on the transition steel plate, and two blocks of crescent moon steel plates are burn-on respectively and are connected on two arm-ties away from an end of transition steel plate;

Nut comprises nut I and nut II, nut I retaining thread bar I and the arm-tie that has the vertical hole of passing of threaded rod I; Nut II retaining thread bar II and supporting component light plate.

Positive progressive effect of the present utility model is: the graphite bearing provision for disengagement of the shield electric machine top chock that the utility model provides has following advantage: the provision for disengagement that the utility model provides is simple in structure, easy to manufacture, all parts machine tools can both be processed.When provision for disengagement was made, each accurate to dimension was less demanding.

The provision for disengagement frock that the utility model provides is easy to use, and is less demanding to operator's technical ability.

The graphite bearing that the provision for disengagement that the utility model provides disassembles is intact, can reuse, and reaches the purpose that saves production cost.The provision for disengagement that the utility model provides is easy to use, has greatly improved removal efficiency.
