Description
[technical field]
The utility model relates to the technical field of auto parts and components, and a kind of be furnished with cold-extruded oil groove bearing
The technical field of universal joint assembly.
[background technology]
Universal joint is the parts realizing the transmission of varied angle power, for needing to change the position of transmission axis direction,
It is " joint " parts of the universal driving device of automobile driving system.Universal joint combines with power transmission shaft, claims
For universal driving device.
Whether there is obvious elasticity that rigid universal joint and flexibility can be divided into universal on torsional direction by universal joint
Joint.Rigid universal joint be divided into nonconstant velocity universal joint conventional for Cardon universal joint, Near constant velocity universal joint such as twin
Universal joint and constant velocity cardan joint such as rzeppa joint three kinds.
Cardan (hookes)universal joint is widely used nonconstant velocity universal joint on automobile.Cardan (hookes)universal joint has one
Individual cross axle, two universal-joint forks and four needle bearings etc. form.Hole on two universal-joint forks is overlapped respectively
On the axle journal of cross axle.So when driving shaft rotates, driven shaft gets final product concomitant rotation, again can be around cross
Axle center swings at certain angle, has thus adapted to angle and the distance needs with change.
Traditional Hooke's joint assembly includes Hooke's joint body, is located at Hooke's joint spindle nose
The bearing in portion, the needle roller being located between bearing and spindle nose and be located at the sealing ring at bearing external port, due to
Mutually move between spindle nose, bearing and needle roller, often offer on spindle nose for increasing the service life shoe cream room and
Spindle nose facing cut cuts out some roads oil groove, makes lubricating oil constantly flow between bearing, spindle nose.The processing of oil groove
Being that milling forms on manufactured cross axis faces, clamping, process be relatively complicated and labour intensive,
The cost making product is consequently increased, and is unfavorable for product competition in the market.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes one and is furnished with cold-extruded oil groove axle
The universal joint assembly held, it is possible to remove the operation of cross axis faces milling oil groove from.
For achieving the above object, the utility model proposes a kind of universal joint assembly being furnished with cold-extruded oil groove bearing,
Including the bearing outer ring body being connected on Hooke's joint spindle nose, it is characterised in that: outside described bearing
Circle body is the sheath structure that one end is provided with opening, and the end face inwall of described bearing outer ring body has been got on the bus interior oil
Circle, outer scraper ring, if being extruded with arterial highway oil groove relative on the boss existed between described interior scraper ring and outer scraper ring.
As preferably, described oil groove is connected between interior scraper ring and outer scraper ring.
As preferably, the outer peripheral face of the openend of described bearing outer ring body is provided with the groove connecting sealing ring.
As preferably, described oil groove cross section bottom line is arc-shaped.
As preferably, described oil sealing includes that oil sealing main body, epipharynx, outer lip, the end of described epipharynx are arranged on
The open outer side of bearing outer ring body is also close to bearing outer ring body openings end face, and bearing is close in the end of outer lip
The outer peripheral face of outer ring body.
The beneficial effects of the utility model: the utility model is by by original spindle nose end face being located at cross axle
On oil groove replaced by the oil groove that squeezes out on bearing outer ring end face inwall, ensureing the overall good profit of product
On the basis of cunning, simplify operation, make the cost of product reduce and be conducive to its competition in the market.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
