Background technique
Thrust-bearing is a kind of bearing conventional in current screw pump, although existing thrust-bearing to a certain degree can carry radial load down, under some specific operation conditions, thrust-bearing is because of the restriction by boundary dimension, larger model can not be selected, often do not reach required load.At present, primary solutions for the demand of load is adopt several thrust-bearing to connect the structural type of putting mostly, but this structure is difficult to ensure all carrying of each bearing, as long as any one bearing damage in tandem group, whole tandem group just cannot use, the working life of complete machine is shorter, and multiple bearing serial connection, be not easy to assembling.
Summary of the invention
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of increase bearing capacity, uniform load, complete machine long service life, and is easy to the screw pump tandem type thrust bearings of assembling.
The utility model solves the technological scheme that its technical problem adopts: this screw pump tandem type thrust bearings, comprise the thrust-bearing of multiple tandem, it is characterized in that: the thrust-bearing of described multiple tandems is be arranged above and below the first thrust-bearing and the second thrust-bearing that arrange, respectively by clutch shaft bearing gland and the second Bearing housing suit on the rotary shaft, the first thrust-bearing and the second thrust-bearing outer ring and bottom support fixing respectively by the first supporting base and the second supporting base for first thrust-bearing and the second thrust-bearing; And the first elastomer is provided with between the first thrust-bearing top and clutch shaft bearing gland, between the top of the second thrust-bearing and the second Bearing housing, be provided with the second elastomer.
Two thrust-bearings be arranged above and below are set, equal separate loading, again by installing elastomer respectively at the top of two thrust-bearings, carry out by independent elastomer the load that uniform distribution thrust-bearing bears, make load suffered by each bearing comparatively even, obviously increasing on the basis of load of thrust bearing thereof bearing capacity, improve the working life of complete machine, decrease the number of times of maintenance, and the component count of bearing pack is less, assembly and disassembly is more convenient.
Bearing protector is installed on described running shaft top; bearing protector bottom connects the coupling being sleeved on running shaft top equally; coupling is pressed on clutch shaft bearing gland; the first supporting base is socketed outside bearing protector; the bottom of the first supporting base is socketed the second supporting base, and the second supporting base bottom connects motor protecter.
The first described supporting base middle inside is provided with boss, installs the first thrust-bearing by boss.
In the middle part of the second described supporting base, outside is provided with projection, is connected, and installs the second thrust-bearing at the top of the second supporting base by projection with the first supporting base.
The first described supporting base bottom inner ring is threaded the second supporting base top, and the joint of the second supporting base and the first supporting base is provided with seal washer.
Have prior art to compare, the beneficial effect that the utility model has is:
Suit two thrust-bearings on the rotary shaft that are arranged above and below are set, equal separate loading, again by installing elastomer respectively at the top of two thrust-bearings, carry out by independent elastomer the load that uniform distribution thrust-bearing bears, make load suffered by each bearing comparatively even, obviously increasing on the basis of load of thrust bearing thereof bearing capacity, improve the working life of complete machine, decrease the number of times of maintenance, and the component count of bearing pack is less, assembly and disassembly is more convenient.
