Description
Technical field:
The present invention relates to a kind of thrust pad, be specifically related to a kind of tilting bush resilient support thrust bearing pad.
Background technology:
In the evolution of tilting thrust bearing, the stress equalization between thrust pad is constantly subjected to the pass of research staff
Note.Cause the factor of discontinuity between thrust pad a lot, such as, cause each thrust pad thickness due to mismachining tolerance
Difference, causes unbalance stress between tile fragment, also has the unbalance loading etc. caused due to system structure factor, and the generation of these factors all can
The performance of strong influence tilting thrust bearing, if excessive by gap edge between thrust pad, results even in whole pushing away
Power bearing arrangement damages.
Research worker processes essence it is also proposed that cross a lot of method of discontinuity equalization between thrust pad, such as raising of solving
Degree, increase balance block structure and employing butterfly spring supporting construction.Although balance block structure to some extent solve tile fragment it
Between equalization problem, but still there is the biggest defect in it, first such a structure increases the volume of tilting thrust bearing,
Reduce equipment reliability of operation, and this structure cannot solve between the thrust pad caused due to system structure unbalance loading
The problem of unbalance stress, with certain limitation in application；Although butterfly spring supports and solves unbalance loading to slide thrust bearing
Impact, but butterfly spring supporting construction belongs to annular brace, self-balancing ability is poor, affects the performance of thrust bearing, and butterfly spring
Difficulty of processing own is big, consistent to ensure the rigidity of each butterfly spring, needs to process substantial amounts of butterfly spring, and sieves from which
Choosing, difficulty of processing is big, and production cost is high, service life, so, a kind of tilting bush elasticity with low cost, safe and reliable of design is propped up
Support thrust bearing pad is the most necessary.
Summary of the invention:
In place of the present invention makes up and improves above-mentioned the deficiencies in the prior art, it is provided that one can be automatically adjusted slope thrust axle
Hold the problem of discontinuity equalization between thrust pad, meet system to the reliability height of slide thrust bearing, compact conformation, performance
Stably wait requirement.
The technical solution used in the present invention is: a kind of tilting bush resilient support thrust bearing pad, this bearing tile includes
Thrust bearing shoe valve and resilient support block, resilient support block is installed on thrust bearing shoe valve, and resilient support block includes spherical support, spring beam and outer
Ring.
Described thrust bearing shoe valve generally circular in shape or fan-shaped.
Described thrust bearing shoe valve and resilient support block are independently processed, and process laggard luggage and join, and are propped up with elastic by thrust bearing shoe valve
After bracer is assembled into thrust pad, then thrust pad is assembled with the collar, be assembled into a set of thrust bearing pad；Work as thrust
When bearing tile is by the thrust of thrust disc, the resilient support block of thrust bearing pad is by the axial thrust of thrust disc, elastic
Spring beam bracer within by the extruding generation elastic deformation of outer shroud and spherical support, regulate each thrust bearing pad it
Between difference in height, make the stress relative equilibrium between each thrust bearing pad.
Described spherical support, spring beam and outer shroud design for integral type.
Beneficial effects of the present invention: the thrust bearing stress regulating power of this structure is strong, simple in construction is reasonable in design, adds
Work is convenient for installation and maintenance, and service life is long, safe and reliable, with low cost, economic and practical, can promote on a large scale and use.
Thrust pad is split as thrust bearing shoe valve and two independent part processing of resilient support block, machines laggard luggage and join.Propping up
By being machined into several elastic beam structure on bracer, one end of each spring beam connects the outer ring portion of a bracer, i.e. with push away
The part that power watt coordinates, the other end connects the spherical support structure of bracer, spherical support structure by spring beam support suspension in
In thrust bearing shoe valve structure；After thrust bearing shoe valve and resilient support block being assembled, a number of thrust pad assembles with the collar, group
Becoming complete thrust bearing, when thrust bearing is by the thrust of thrust disc, the resilient support block of thrust pad is by thrust disc
Axial thrust, the spring beam within resilient support block by outer shroud and spherical support block extruding produce elastic deformation, regulation
Difference in height between each thrust pad, makes the stress relative equilibrium between each thrust pad.Additionally in real process, bullet
Property the quantity of beam and big I be designed according to the size of thrust suffered by thrust bearing, design the spring beam of different-stiffness,
Meet different thrust requirements, make the thrust pad stress of slide thrust bearing reach relative equilibrium, thus improve thrust bearing
Performance.

Detailed description of the invention:
With reference to each figure, a kind of tilting bush resilient support thrust bearing pad, this bearing tile includes thrust bearing shoe valve 1 and resilient support block
2, resilient support block 2 is installed on thrust bearing shoe valve 1, and resilient support block 2 includes spherical support 201, spring beam 202 and outer shroud 203；Push away
Power watt 1 generally circular in shape or fan-shaped；Thrust bearing shoe valve 1 and resilient support block 2 are independently processed, and process laggard luggage and join, will push away
After power watt 1 and resilient support block 2 are assembled into thrust pad, then thrust pad is assembled with the collar, be assembled into a set of thrust
Bearing tile；When thrust bearing pad is by the thrust of thrust disc, the resilient support block 2 of thrust bearing pad is by thrust disc
