Technical field
This utility model relates to the set pressure device of a kind of rotor bearing, is used for being pressed in bearing holder (housing, cover) the main shaft of rotor
On.
Background technology
The structure of rotor main shaft 2 is, the stage casing of rotor main shaft is the iron core portion arranging iron core, the two of iron core portion
Side is the bearing portion 3 arranging bearing, and the outside of bearing portion is the connecting portion 4 of rotor main shaft and external connection, wherein iron core
The diameter in portion is more than the diameter of bearing portion, and the diameter of bearing portion is more than the diameter of connecting portion.The method of casing pressure bearing on main shaft
It is first to press the bearing of one end of main shaft, press the bearing of the other end of main shaft the most again.This kind of method efficiency is low, for improving bearing
Casing pressure work efficiency, it is necessary to design one set pressure device.
Summary of the invention
The technical problems to be solved in the utility model is to provide the set pressure device of a kind of rotor bearing to ensure bearing casing pressure
Quality and work efficiency.
The technical solution of the utility model is, the set pressure device of a kind of rotor bearing, and it includes base 12, is arranged on base
First bearing 8 on the upper left side, it is arranged on base second bearing 10 on the right, it is characterized in that, the first bearing is fixed with
Positioning sleeve 5, the long through-hole being provided with on tappet 9, tappet and the second bearing on the second bearing is slidably matched, and positioning sleeve is same with tappet
Axis；Maximum spacing between on the right side of positioning sleeve and on the left of tappet slightly larger than the length of rotor main shaft, the hole of positioning sleeve with
The connecting portion 4 of rotor main shaft left end matches；Tappet left end is provided with blind hole, blind hole and rotor main shaft right-hand member connecting portion
4 match；Positioning sleeve and tappet coaxial line；Tappet right-hand member and an oil cylinder 11 connect, hydraulic oil cylinder driving tappet side-to-side movement.
The beneficial effects of the utility model are, the bearing at rotor main shaft two ends can simultaneously casing pressure, improve work effect
Rate；Bearing power suffered by its end face during casing pressure is uniform, does not haves the inclined phenomenon of pressure, it is ensured that casing pressure quality.

Detailed description of the invention
In conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
The set pressure device (seeing Fig. 1) of a kind of rotor bearing, is used for being pressed on the main shaft of rotor bearing 1 set.Turn
The set pressure device of sub-bearing, the first bearing 8 including base 12, being arranged on the left side on base, is arranged on base the of the right
Two bearings 10, are fixed with positioning sleeve 5 on the first bearing, are provided with on tappet 9, tappet and the second bearing on the second bearing
Long through-hole is slidably matched, positioning sleeve and tappet coaxial line；Maximum spacing between on the right side of positioning sleeve and on the left of tappet is slightly larger than electricity
The length of machine rotor main shaft 2, matches with the connecting portion 4 of rotor main shaft left end in the hole of positioning sleeve；Tappet left end is provided with blind
Hole, blind hole matches with the connecting portion 4 of rotor main shaft right-hand member；Positioning sleeve and tappet coaxial line；Tappet right-hand member and an oil cylinder
11 connect, hydraulic oil cylinder driving tappet side-to-side movement.
Using method of the present utility model is, first on rotor main shaft, the bearing portion 3 at two ends overlaps upper bearing (metal) 1, so in advance
After the right-hand member of rotor main shaft inserted in the blind hole of tappet, make oil cylinder enter with certain pressure left side, rotor main shaft
Left end enters in positioning sleeve, and positioning sleeve right side and tappet left side are the compressive plane to bearing, enter the work of power on a left side for oil cylinder
Under with, by the bearing portion 3 being squeezed in rotor main shaft of bearing, bearing makes the oil cylinder right side move back after compressing.
For convenience of the location of rotor main shaft, described positioning sleeve right-hand member extends a U-shaped portion 7, and the cross section of U-shaped portion is
U-shaped (sees Fig. 2), and the inner arc radius of U-shaped portion is equal with the radius of positioning sleeve, the outer arc radius of U-shaped portion and the cylindrical of positioning sleeve
Radius is equal；The forming method of U-shaped portion is, a gap opened by the wall at positioning sleeve right-hand member, the width of gap and the aperture of positioning sleeve
Equal；Described tappet left end also extends a U-shaped portion 7；The end face of U-shaped portion is the compressive plane to bearing.By rotor master
The connecting portion 4 of axle is shelved in the groove of U-shaped portion, can make rotor main shaft, positioning sleeve and tappet coaxial line.
