Abstract
The utility model relates to a universal joint, and in particular to a universal joint which can prevent leakage of grease and entrance of slush comprising a cross shaft, the four end parts of the cross shaft being respectively provided with a shaft end, the shaft ends being respectively sleeved with a bearing mechanism, among the bearing mechanisms being provided oil cups, the oil cups and the oil holes within the cross shaft being communicated with each other. The universal joint of the utility model can prevent leakage and slush, reduce labor intensity and increase working efficiency.
Description
Technical field
The utility model is a kind of universal joint, particularly a kind of universal joint that can reach anti-lubricating grease leakage and prevent the anti-leak water proof and dust proof that muddy water enters.
Background technique
On torsional direction, whether there is tangible elasticity can be divided into rigid universal joint and flexible universal joint by universal joint in the prior art.Rigid universal joint can be divided into three kinds of nonconstant velocity universal joint (commonly used for Cardon universal joint), near constant velocity universal joint (as the twin universal joint) and constant velocity universal joints (as rzeppa universal joint) again.
Cross shaft rigid universal joint is a widely used nonconstant velocity universal joint on the automobile.Cardan universal joint is by a cross axle, two universal-joint forks and four compositions such as needle bearing.Hole on two universal-joint forks is enclosed within respectively on two pairs of axle journals of cross axle.When driving shaft rotated, driven shaft both can rotate thereupon like this, can swing in any direction around the spider center again, had so just adapted to the needs that angle and distance change simultaneously.Cross shaft rigid universal joint has simple in structure, the advantage that transmission efficiency is high, but, the oil sealing of present cardan universal joint all is to adopt the common circular seal ring of circular or V-arrangement, the sealing effect of this oil sealing on Hooke's joint is poor, inner lubricant oil is easily to external leakage, and outside dust, muddy water etc. enter universal joint inside easily.Influenced the performance of whole universal joint, and reduced its working life.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of universal joint of anti-leak water proof and dust proof is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of universal joint of anti-leak water proof and dust proof, comprise the cross axis body, four ends of cross axis body are respectively equipped with axle head, are with gear mechanism on the described axle head respectively, be provided with lubricating cup between described gear mechanism and gear mechanism, the oil-through hole in described lubricating cup and the cross axis body is connected.This structure has dustproof preferably effect, on oil sealing, increase snap ring, compress the internal diameter of oil sealing by snap ring, thereby compress trunnion journal, thereby reach anti-lubricating grease leakage and prevent the purpose that muddy water enters, adopt the axle bowl of nylon simultaneously in the increase of axle head, the further dustproof effect that increases, because the axle bowl that nylon is done has stronger toughness, in assembling processing, only need very little impulse force, just can smoothly the axle bowl be put into trunnion journal and get on, improve labor intensity thereby reach, improve the purpose of output.
As preferably, described gear mechanism comprises outer ring, needle roller, snap ring, needle roller catch and axle bowl, the outer ring is enclosed within on the axle head, be provided with needle roller between described axle head and the outer ring, be with the needle roller catch in the axle head, the needle roller catch contacts with needle roller, described axle bowl is enclosed within the bottom of axle head, be provided with oil sealing between described axle bowl and axle head, described oil sealing is by snap ring and axle head clamping mutually, and described needle roller catch, oil sealing and snap ring are complementary.
As preferably, described lubricating cup is skewed.
As preferably, described axle bowl is a nylon spare.
Therefore, the universal joint of the anti-leak water proof and dust proof that the utility model provides, simple in structure, have dustproof anti-leak result, reduce assembling labor intensity, enhance productivity.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
