Description
Technical field
The utility model relates to bearing mnanufacture technical field, specifically a kind of composite guideway bearing for military vehicle conveying shell.
Background technique
In prior art, the structure of linear rail bearing has multiple, as cylindrical roller class, deep groove ball bearing class, tapered roller bearing class, linear bearing, ball screw linear bearing etc., can to-and-fro motion on straight line type guide rail, the combined loads such as larger axial load, radial load can be born simultaneously, integrate supporting, rotation, transmission, the several functions such as fixing.Generally, guide rail bearing self all with mounting hole, lubricant oil and seal arrangement, the different demands of various main frame under different working condition can be met; On the other hand, guide rail bearing itself has compact structure, guides conveniently, installs convenient and be easy to the features such as maintenance, is widely used among the precision equipments such as food machinery, package packing machine, medical machinery, printing machinery, textile manufacturing machine, instrument manufacturing, automobile making, machine tool, numerical control machine tool, robot and Digital Three-Dimensional coordinate measurment instrument or special machine industry.
At present, standard rail bearing is confined to linear rail, comprises V-arrangement, circle, square rail etc.And for type ring-shaped guide rail, due to guide rail size restriction, requirement can bear radial and axial power, can turn to flexibly at the level place of guide rail and circular arc place, and common guide rail bearing cannot satisfy the demands.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of composite guideway bearing, to realize turning to flexibly at the level place of type ring-shaped guide rail and circular arc place.
For achieving the above object, outer ring one of the present utility model, retainer between outer ring two and inner ring are built with steel ball; Retainer is split-type structural, and inner ring and bearing support are combined into one; The side of inner ring is provided with two pairs of lugs, and with for bearings mounted bearing pin in lug, bearing pin is contained on lug; Outer ring two and ball bearing roll at the horizontal segment of guide rail, and when bearing is turn-taked, outer ring two and ball bearing getaway, two outer rings one contact with each other at the arc section of guide rail, rotate.
Described outer ring one, outer ring two are with peach-shaped raceway groove one; The external diameter of outer ring one is greater than the external diameter of outer ring two.
Described inner ring is with peach-shaped raceway groove two; With the pin-and-hole for installing chain in bearing support; With the protrusion pawl for mounting spring and block on inner ring.
The utility model is biserial 4 angular contact bearings, be arranged on type ring-shaped guide rail, installing space is narrow and small, requires that bearing is at ring-shaped guide rail flexible rotating simultaneously, ring-shaped guide rail comprises horizontal segment and arc section, outer ring two and ball bearing roll at the horizontal segment of guide rail, when bearing is turn-taked, and outer ring two and ball bearing getaway, two outer rings one contact with each other at the arc section of guide rail, rotate, reach steering-effecting, complete conveying shell function, bear radial force and axial impact force.
The utility model compared with prior art, has the following advantages:
1., installing space is little: radial dimension of the present utility model is little, and wall thickness is thinner, changes standard rolling bearing structure, inner ring and bearing support is combined into one, and is saving installing space to a greater extent.
2., precision is high: the heat treatment method that outer ring adopts vacuum hardening and correction to combine, inner ring adopts part surface quenching, substantially reduces amount of deformation, improves bearing accuracy.
3., rigidity and bearing capacity large: adopt biserial 4 angular contact ball bearings, the structure that inner ring and bearing support integrate, steel ball increase, improves the bearing capacity of bearing.
4., internal structure flexibly: adopt split type retainer, retainer intensity and bearing flexibility can be improved, be convenient to steel ball and install.
5., anti-corrosion ability: outer ring adopts stainless steel, and inner ring adopts oxidation processes, improves the anti-corrosion ability of bearing.
6., easy for installation, quick: to adopt inner ring and bearing support integrative-structure, make bearing form modularization, componentized, safeguard that installation is more convenient, quick.
