Abstract
The invention relates to a multistage thrust ball bearing-pack uniform loading performance test rack which is composed of a static condition simulation system and a loading system. The static condition simulation system is composed of a spindle, a compression sleeve, an upper end plate and an intermediate end plate; the intermediate end plate and the upper end plate are supportively connected through four support rods arranged by 90 degrees, threads are machined in two ends of each support rod, and the two end places are axially, oppositely and adjustably fixed through nuts, so that positions where two centers of the two end plates are located are on the same axial line; a multistage ball bearing pack is mounted on the spindle and is fixed between the intermediate end plate and the upper end plate by adjusting the nuts. Bearing situation of bearings of each stage after loading of the bearing pack can be detected by arranging resistance strain gauges on outer cages of the bearings of each stage in the bearing pack, and uniform loading situation of the bearing pack can be obtained; continuous loading of the rack can be realized, and bearings of different stages can be adapted.
Description
Technical field
The present invention relates to a kind of multistage thrust ball bearing group and all carry performance test stand, belong to petroleum drilling laboratory experiment equipment.
Background technology
Multistage thrust ball bearing group is that one both can bear radial load, can bear again the special bearing of axial load, be widely used among aeromotor, propeller for vessels, the hydraulic turbine, mud motor.Prove through experiment, it all carries performance has very large impact to its mission life, only has when each supplementary bearing load diatibution in bearing pack is even or be tending towards even, just can reach its serviceable life the longest, and practical bearing group is after processing and manufacturing out, do not know that it all carries behavior pattern.According to the scientific paper published and patent, not yet disclose the experimental provision all carrying performance testing multistage thrust ball bearing group abroad.The present invention all carries performance in order to what test multistage thrust ball bearing group, with understand multistage thrust ball bearing group operationally all carry situation, and then improve the serviceable life of bearing pack.
Summary of the invention
The object of the invention is all to carry performance in order to what test multistage thrust ball bearing group, provide a kind of multistage thrust ball bearing group all to carry performance test stand, all carry performance in order to what test multistage thrust ball bearing group, and then improve bearing pack actual life.
The technical solution used in the present invention is: a kind of multistage thrust ball bearing group of the present invention all carries performance test stand, is made up of static(al) Simulated System and loading system.Described static(al) Simulated System is by main shaft, and clamping sleeve, upper head plate and middle end plate form.Middle end plate is connected with the they sup-port be arranged at an angle of 90 by four between upper head plate, support bar two ends machining screw, also can regulate fixing for its two end plates relative axial position, to ensure that present position, the two end plates center of circle is on same axial line with nut.Multi-stage ball bearing pack is arranged on main shaft, described main shaft between middle end plate and upper head plate, by setting nut by clamping sleeve compress thus multi-stage ball bearing pack is fixed between middle end plate and upper head plate.
Described loading system is then by support set, and lifting jack, supports end plate and form.Also four are adopted to become 90 degree of support bars distributed by its support and connection between middle end plate with support end plate; Support bar two ends machining screw; Adopt studs to connect at support end plate place, connect fixing at middle end plate place nut and can regulate, to ensure middle end plate and to support the present position, the center of circle of end plate on same axial line.Lifting jack is installed on middle end plate and supports between end plate, is positioned on same axis.Lifting jack supports main shaft by support set.
Also the they sup-port be arranged at an angle of 90 with four between upper head plate with support end plate is connected, support bar two ends machining screw, adopts studs to connect, connect fixing (can regulate) at upper head plate place nut at support end plate place.Thus make whole stand become as a whole, uniform force.
The present invention has following characteristics and advantage: 1. stand can realize the loading of continuous variable; 2. stand can adapt to different progression bearing; 3. stand can science measure Multistage bearing stand under load after all carry situation.
Accompanying drawing explanation
Fig. 1 is that a kind of multistage thrust ball bearing group of the present invention all carries performance test stand structural representation;
Fig. 2 is the plan structure schematic diagram of Fig. 1.
In figure: 1. main shaft 2. clamping sleeve 3. upper head plate 4. middle end plate 5. support set 6. lifting jack 7. supports end plate 8. multi-stage ball bearing 9. support bar 10. nut 11. nut.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described further:
As shown in Fig. 1, Fig. 2, a kind of multistage thrust ball bearing group of the present invention all carries performance test stand, is made up of static(al) Simulated System and loading system.With middle end plate 4 for boundary, static(al) Simulated System and loading system can be divided into.Described static(al) Simulated System is by main shaft 1, clamping sleeve 2, upper head plate 3 and middle end plate 4 form, by the support and connection of four support bars be arranged at an angle of 90 9 between middle end plate 4 and upper head plate 3, support bar 9 two ends machining screw, also can regulate fixing for its two end plates relative axial position, to ensure that present position, the two end plates center of circle is on same axial line with nut 10.
Described loading system is by support set 5, and lifting jack 6, supports end plate 7 and form.Lifting jack 6 is at middle end plate 4 and support between end plate 7, and lifting jack 6 supports main shaft 1 by support set 5.
As shown in Figure 1, by multi-stage ball bearing 8 with press cover 2 and be arranged on main shaft 1.Bottom bearing, inner ring is just seated on the shaft shoulder of main shaft 1, and outer ring is then seated on middle end plate 4, by regulating the nut 10 on each support bar 9, upper head plate 3 is positioned on the outer ring of bearing upper end, and clamping sleeve 2 is positioned on bearing inner race.Again by regulating the nut 11 on main shaft by clamping sleeve 2 being fixed on bearing inner race tightly.
By regulating lifting jack 6, the load of different size can be made to act on support set 5, and by support set 5, load is passed to main shaft 1, and then making load applying in bearing inner race, realize simulation thrust ball bearing duty.The outer race of bearing pack bearing at different levels arranges resistance strain gage, after loading, then can measure the loading conditions of bearing at different levels in bearing pack, thus can know bearing pack all carry situation.Regulate nut 11 position on upper head plate 3 and main shaft 1, the progression of changeable bearing pack centre bearer, thus the progression changing bearing can be realized.
