Description
Technical field
The present invention relates to bearing mnanufacture technical field, a kind of composite guideway bearing for military vehicle conveying shell.
Background technology
In prior art, the structure of line slideway bearing has multiple, such as cylindrical roller class, deep groove ball bearing class, taper roll bearing class, linear bearing, ball-screw linear bearing etc., can move back and forth on linear type guide rail, the combined loads such as bigger 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 installing hole, lubricating oil and sealing device, can meet the different demands of various main frames under different working condition；On the other hand, guide rail bearing itself has the features such as compact conformation, guiding is convenient, it is convenient to install and is easily maintained, and is widely used among the precision equipments such as food machinery, package packing machine, medical machinery, printing machinery, textile machine, instrument manufacturing, automobile making, machine tool, Digit Control Machine Tool, robot and Digital Three-Dimensional coordinate measurment instrument or special machine industry.
At present, standard rail bearing is confined to line slideway, including V-arrangement, circle, square rail etc..And for type ring-shaped guide rail, owing to guide rail size limits, it is desirable to radial and axial power can be born, can turn to flexibly at the level of guide rail and at circular arc, common guide rail bearing cannot meet demand.
Summary of the invention
For overcoming the deficiencies in the prior art, the goal of the invention of the present invention is to provide a kind of composite guideway bearing, to realize turning at the level of type ring-shaped guide rail and at circular arc flexibly.
For achieving the above object, the outer ring one of the present invention, retainer between outer ring two and inner ring are built with steel ball；Retainer is split-type structural, and inner ring is combined into one with bearing block；The side of inner ring is provided with two pairs of lugs, and with the bearing pin for installing bearing 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 more 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 block；With the protrusion pawl for installing spring and block on inner ring.
The present invention is 4 angular contact bearings of biserial, being 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 includes 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 to carry shell function, bear radial force and axial impact force.
The present invention compared with prior art, has the advantage that
1., installing space is little: the radial dimension of the present invention is little, and wall thickness is relatively thin, changes standard rolling bearing structure, is combined into one with bearing block by inner ring, saves installing space to a greater extent.
2., precision is high: outer ring uses the heat treatment method that vacuum hardening and correction combine, and inner ring uses part surface quenching, substantially reduces deflection, improves bearing accuracy.
3., rigidity and bearing capacity are big: using 4 angular contact ball bearings of biserial, the structure that inner ring and bearing block integrate, steel ball increases, improves the bearing capacity of bearing.
4., internal structure flexibly: use split type retainer, retainer intensity and bearing motility can be improved, it is simple to steel ball is installed.
5., anti-corrosion ability: outer ring uses stainless steel, and inner ring uses oxidation processes, improves the anti-corrosion ability of bearing.
6., easy for installation, quick: use inner ring and bearing block integrative-structure, make bearing form modularity, componentized, safeguard install more convenient, quick.

Detailed description of the invention
Such as Fig. 1, Fig. 2, Fig. 3, shown in Fig. 7, outer ring 1, retainer 4 between outer ring 22 and inner ring 5 is built with steel ball 3, steel ball 3 is precision stainless steel steel ball, outer ring 1, outer ring 22 is with peach-shaped raceway groove 1, inner ring 5 is with peach-shaped raceway groove 2 14, described peach-shaped raceway groove is conducive to improving radial direction and the axial carrying capacity of bearing, the external diameter of outer ring 1 is more than the external diameter of outer ring 22, it is primarily to facilitate when turning, outer ring 1 contacts with each other, outer ring 22 getaway, the wall thickness of outer ring is relatively thin, correct with corresponding frock after using heat treatment vacuum hardening, so that deflection meets technology requirement.Retainer 4 is split-type structural, 23 split retainers combine, can improve the intensity of retainer 4, being easily installed, each split retainer is respectively arranged with two steel ball mouths, and steel ball oral area has the magnitude of interference, steel ball 3 can be pinned, bearing flexible rotating can be made again simultaneously.Inner ring 5 is combined into one with bearing block 15, saves installing space to a greater extent；With the pin-and-hole 16 for installing chain in bearing block 15, chain-driving bearing block 15 moves on the rail 9, and chain drives underdrive at sprocket wheel, it is achieved the movement of shell；With for installing the protrusion pawl 12 of spring 11 and block 10 in order to limit moving axially of shell on inner ring 5, the side of inner ring 5 is provided with two pairs of lugs 8, and with the bearing pin 7 for installing ball bearing 6 in lug 8, bearing pin 7 is contained on lug 8.
As shown in Fig. 4, Fig. 5, Fig. 6, chain 21 drives bearing block to move on the rail 9, chain 21 drives underdrive at sprocket wheel 20, outer ring 22 and ball bearing 6 roll at the horizontal segment 18 of guide rail 9, when bearing is turn-taked, and outer ring 22 and ball bearing 6 getaway 9, two outer rings 1 contact with each other at the arc section 19 of guide rail 9, rotate, reaching the requirement turned, when travelling to when releasing position 22, the shell 17 in bearing is pushed out.
