Description
Technical field
The utility model relates to the fields of universal joint, and in particular to a kind of biserial oblique circular cylinder roller bearing universal joint.
Background technique
Existing universal joint is made of cross axle and universal joint bearing mostly, and wherein universal joint bearing includes bearing holder (housing, cover), rolling
Needle, oil sealing and dust cover etc..Particularly, usually there is duplex needle for medium and heavy universal joint bearing, led to avoid needle roller is too long
The fracture failure of cause.Realize that parallel rolling, oil sealing and dust cover are mounted on bearing holder (housing, cover) using needle roller between cross axle and bearing holder (housing, cover)
The spindle nose of cross axle is close in open end and inside, prevents lubricating grease excessive and enters Bearing inner with magazines such as mud.This is typical
The medium and heavy universal joint assembly technical solution of tradition, it can be achieved that the functions such as driving torque and movement, have certain intensity, fatigue
With wear-out life etc..
Universal joint described in the prior art, since needle roller ontology smallest number is more, causes dress needle cumbersome, needs dedicated set in assembly
It is standby, and axial sliding can be done on the cross axle diameter of axle for needle roller so that gimbal structure is unstable, is easy to appear down needle or axis
Hold phenomena such as sliding falls off；For needle roller in Bearing inner without fixed designs such as retainers, freedom degree is more, causes irregular needle roller
Shock loading；It is effective contact length between needle roller and axle journal and axle sleeve is a parallel lines, the load that can be carried is limited；Due to
It trunnion journal surface must be through special thermal treatment, such as carburizing and impewdance matching, to improve the wearability of journal surface, but because quenching
Hard formation thickness is difficult to control, and is quenched technique and be will increase journal surface brittleness, and surface toughness and plasticity etc. are reduced；Journal surface
Roughness requirements are higher, manufacture difficulty and higher cost；Cardan axis bears the influence of high speed centrifugation power and torque load, especially
It is in biggish setting angle, needle bearing has axial float behavior, and bearing outer ring has flight behavior etc..It is generally speaking existing
The medium and heavy universal joint of technology has the problems such as assembly is complicated, bearing capacity is small, wear-out life is not high.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of biserial oblique circular cylinder Roller Shaft
Hold universal joint.
The purpose of this utility model is completed by following technical solution: this biserial oblique circular cylinder roller bearing is universal
Section mainly includes cross axle B, biserial oblique circular cylinder roller bearing, is set with biserial oblique circular cylinder roller on four diameters of axle of cross axle B
Bearing, biserial oblique circular cylinder roller bearing are made of cylindrical roller, retainer, sealing ring B, inner ring, outer ring, and inner ring and outer ring is coaxial
It installs, double-row cylindrical roller is installed between inner ring and outer ring, cylindrical roller is limited by retainer, biserial oblique circular cylinder roller bearing
Both ends are provided with sealing ring B, and sealing ring B plays sealing and dustproof.
The double-row cylindrical roller is arranged symmetrically at an angle.
It is interference fitted between the inner ring of the biserial oblique circular cylinder roller bearing and the axle journal of cross axle B.
The utility model has the following beneficial effects:
1, the utility model realizes that modularization, assembly is simple, stability is good, improved efficiency, in addition biserial oblique circular cylinder roller
Bearing itself has stable structure, and rigidity is good, and the strong advantage of bearing capacity makes bearing capacity improve a lot.
2, the utility model is since cylindrical roller is tilted-putted, so that the contact surface of roller and working face becomes larger, increases
The effective contact area for having added cylinder needle roller improves the contact stress concentration problem of working face, improves the wear-resisting of universal joint
Damage the service life.
3, Interference Fit Design between the utility model bearing inner race and axle journal, oblique circular cylinder roller bearing structure can effectively hinder
The only running axial float of cross axle, while can compensate for the circumferential deformation that lower spindle nose is acted on due to large torque, improve universal joint
Bearing capacity.
4, for the utility model due to eliminating driving universal joint bearing housing structure, new gimbal structure is more compact, returns
Turn radius and reduce section, fork installation space can be saved to such as driving-shaft assembly type component.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the medium and heavy universal joint bearing of the prior art.
Fig. 2 is the structural schematic diagram of the utility model.
Fig. 3 is the structural schematic diagram of the utility model biserial oblique circular cylinder roller bearing.
Description of symbols: cross axle A1, axle sleeve 2, needle roller 3, gasket 4, sealing ring A5, dust cover 6, cross axle B7, double
Column oblique circular cylinder roller bearing 8, cylindrical roller 9, retainer 10, sealing ring B11, inner ring 12, outer ring 13.
Specific embodiment
Detailed introduction is done to the utility model below in conjunction with attached drawing:
Embodiment: as shown in the picture, this biserial oblique circular cylinder roller bearing universal joint mainly includes cross axle B7, biserial
Oblique circular cylinder roller bearing 8 is set with biserial oblique circular cylinder roller bearing 8, biserial oblique circular cylinder roller on four diameters of axle of cross axle B7
Bearing 8 is made of cylindrical roller 9, retainer 10, sealing ring B11, inner ring 12, outer ring 13, and inner ring 12 and outer ring 13 are co-axially mounted,
Double-row cylindrical roller 9 is installed, cylindrical roller 9 is limited by retainer 10, biserial oblique circular cylinder roller between inner ring 12 and outer ring 13
8 both ends of bearing are provided with sealing ring B11, and sealing ring B11 plays sealing and dustproof.
The double-row cylindrical roller 9 is arranged symmetrically at an angle.
It is interference fitted between the inner ring 12 of the biserial oblique circular cylinder roller bearing 8 and the axle journal of cross axle B7.
Modular biserial oblique circular cylinder roller bearing 8 need to be only set on cross axle B7 axle journal by the utility model when assembling,
It is interference fitted between bearing inner race 12 and axle journal, assembly is simple, and stability is good.And due in biserial oblique circular cylinder roller bearing 8
Cylindrical roller 9 is slant setting, so that cylindrical roller 9 and the contact area of working face are big, bearing capacity is strong.
It is understood that it will be understood by those skilled in the art that the technical solution of the utility model and utility model structure
Think of is subject to equivalent substitution or change all and should belong to the protection scope of the utility model the attached claims.
