Abstract
The utility model relates to a connecting part of the mechanical industry, in particular to a universal joint coupling for a step-type steel plate stamping bearing. A step is arranged at the upper opening part of the bearing, and the external diameter of the bearing opening is gradually reduced inwards. The utility model has the advantages of reasonable and simple structure, low processing cost, convenient and simple assembly, simple and convenient manufacturing technology, good lubrication, small friction resistance, and the like.
Description
Technical field
The utility model relates to a kind of union piece of mechanical industry, relates in particular to a kind of step type steel plate impulse bearing universal joint.
Background technique
Hooke's joint is applied to the transmission shaft of various automobiles, engineering machinery etc., transmits rotation torque, is very important component in the transmission system.In traditional design, four needle roller bearing without inner rings of universal joint adopt needle roller to assemble, its outer ring is adopted 20Cr or 20CrMnTi material usually, form through forging, machining, heat-treatment quenching, design the needle roller of circumferential arrangement on the interior raceway of bearing, cooperating with cross axle becomes the universal-joint cross trunnion assembly.Though this Hooke's joint is widely used, since the needle roller processing cost height in the bearing, the assembling difficulty, bearing outer ring must be made with alloy structure quenching heat treatment technology, cost is higher, for the occasion of low speed and large torque, does not also occur replacing the universal joint of needle bearing at present.The utility model patent of the needle bearing of a universal joint by name, the patent No. is CN91202827.0, mainly be to be provided with central authorities to be the cross oil duct of circular hole at bottom end place, bearing inner casing hole, wherein the quadripolar corners at the cross oil duct is symmetrical arranged a circular chase to inner casing aperture wall according to the center, needle roller is arranged on this circular chase, this structure in time flows on the needle roller lubricant oil, makes needle roller and universal joint obtain preferable lubrication effect, and helps the assembling of needle roller.This structure is lower working life, and cost of production is higher.
Summary of the invention
The utility model mainly is at existing in prior technology processing cost height, the assembling difficulty, complex manufacturing, lubricated relatively poor, the technical problem of the bigger grade of surface friction drag, provide a kind of rational in infrastructure simple, processing cost is lower, and easy to assembly simple, production technology is easy, better lubricated, the step type steel plate impulse bearing universal joint that surface friction drag is less.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: bearing position suitable for reading is provided with step, and dwindles gradually in the bearing mouth outer radial.The root of step is provided with and the external diameter connection inclined, the time plays the effect of guiding in order to make the bearing transmission joint fork of packing into, is beneficial to assembling.Make the difficult play up and down of needle roller in the bearing simultaneously, needle roller is worked on the position of setting, improve the working life of universal joint bearing.
As preferably, the bearing mouth is provided with oil sealing, and oil sealing is outside equipped with skeleton, and the skeleton upper oral part has flange.Turnup structure formula oil sealing is by the upper oral part of secure fixation at race ring, and the step external diameter sealing with cross axle makes oil seal lip be radial spring seal, good airproof performance, and also the cross axle step is by correct grinding, and wear-out life improves greatly.
As preferably, bearing face is provided with two plane steps, and first step is arranged between bearing inner wall and the bearing face, and second step is arranged on the bearing face.Bearing face is applied to contact with the axle journal end face of cross axle, makes things convenient for the location of universal joint assembly length, because the boss diameter is less, makes it cooperate flexibility better with cross axis faces.
As preferably, have some small ruts that are evenly distributed on the second step.Lubricating grease drops in the pit, in use is slidingly matched with cross axis faces, prevents the wearing and tearing of boss, increases the service life.
As preferably, the round radius of bearing face is between 0.3mm-0.8mm.Bull nose is unfavorable for that more greatly jump ring fixes, and bearing flies out from the joint fork easily, security incident occurs.In the time of between 0.3mm-0.8mm, the jump ring fixation, safe and reliable.
Therefore, the utlity model has characteristics such as simply processing cost is lower, and easy to assembly simple, production technology is easy, and is better lubricated, and surface friction drag is less rational in infrastructure.
