Abstract
The utility model relates to a universal joint assembly, in particular to a high-strength universal joint assembly, which mainly aims at solving the technical problems that in the prior art, a universal joint has poor strength and short service life because a cross joint of the universal joint is made of 20CrMnTi materials; the universal joint has poor sealing performance because a cross shaft of the universal joint has no inclined plane and the contact performance between a sealing part and the cross shaft is poor; dust easily entering the inside of the universal joint assembly results in abrasion between the cross shaft and a bearing seat; and the like. The high-strength universal joint assembly comprises the cross joint (1) and is characterized in that an oil cup (2) is arranged in the middle of the cross joint (1), and four end portions of the cross joint are respectively sleeved in an outer ring (3). A plurality of double-row rolling pins (4) are arranged between the insides of the outer rings and the end portions of the cross joint, an inclined plane (5) is arranged at the position of a shaft neck of the cross joint (1), an oil sealing mechanism is arranged on the inclined plane, and the cross joint (1) is made of SAE8620 alloy steel.
Description
Technical field
The utility model relates to a kind of universal joint assembly, especially relates to a kind of high tenacity universal joint assembly.
Background technique
Universal-joint cross trunnion of the prior art is generally all formed by middle axis body and with the arm that middle axis body links into an integrated entity.Chinese patent discloses a kind of high tenacity Hooke's joint (notice of authorization number: CN 2464984Y); It comprises cross axle and is arranged on the needle roller around the cross axle spindle nose and puts and outer ring that needle roller is outer; The end of outer ring is provided with packing holder, on said packing holder, is provided with seal ring skeleton and seal placed on it; And the inboard of described seal is provided with tilting outer lip and inside middle lip and the inner lip of lip successively, and two lips contact with the axle journal of cross axle; Tiltedly be provided with the grinding undercut of annular between internal face and the needle roller end face ring, the plane of technology groove connects really in flat end needle rollers end face and the bearing.But the cross of this universal joint joint is to adopt the 20CrMnTi material to process; Therefore its intensity is relatively poor, and working life is shorter, and the cross axle of universal joint is not provided with the inclined-plane; The contact of Sealing and cross axle is relatively poor; Therefore its sealability is relatively poor, and dust enters into universal joint assembly inside easily, makes to be easy to generate wearing and tearing between cross axle and the bearing support.
The model utility content
The utility model provides a kind of high tenacity universal joint assembly, and it mainly is that the cross joint of solution existing in prior technology universal joint is to adopt the 20CrMnTi material to process, so its intensity is relatively poor; Working life is shorter; And the cross axle of universal joint is not provided with the inclined-plane, and the contact of Sealing and cross axle is relatively poor, so its sealability is relatively poor; Dust enters into universal joint assembly inside easily, makes the technical problem that is easy to generate wearing and tearing etc. between cross axle and the bearing support.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The high tenacity universal joint assembly of the utility model comprises the cross joint, and described cross joint middle part is provided with lubricating cup; Four ends of cross joint all are socketed with an outer ring; Be provided with some needle rollers between inside, outer ring and the cross joint end, needle roller is double needle roller, and the axle journal place of cross joint is provided with the inclined-plane; The inclined-plane is provided with oil sealing mechanism, and the cross joint is processed for the SAE8620 alloyed steel.The cross axle of the utility model replaces to the SAE8620 alloyed steel with original 20CrMnTi material, makes that the intensity of whole cross axle is stronger, and working life is longer.The inside of outer ring can have oil storage tank, is used for preserving lubricating grease, thereby guarantees that assembling back needle roller rotates flexibly, oil sealing is intact.
As preferably, described oil sealing mechanism comprises that section is the metal frame of " L " type, is fixed with oil sealing on the metal frame, and oil sealing one end is provided with oil seal collar, and the sealing lip of oil sealing contacts respectively on inclined-plane and oil seal collar.Oil sealing can prevent that dust from entering into universal joint assembly inside, also can prevent that the inner fluid of universal joint assembly from flowing to outside the universal joint through the slit of cross joint with the outer ring simultaneously.
As preferably, be provided with pad between the end face of described cross joint end and the inside of outer ring.Pad can be processed by nylon, like this needle roller when rotated, needle roller and cross joint end can not touch the inside of outer ring, reduces wear, and has reduced noise.
As preferably, be provided with dust-proof cover between the inner of described outer ring and the cross joint.Can prevent further that dust from entering into Hooke's joint inside.
Therefore, the cross axle of the utility model adopts the SAE8620 alloyed steel to process, and makes that the intensity of whole cross axle is stronger; Working life is longer; And the axle journal place at cross axle is provided with the inclined-plane, adds oil sealing mechanism at the place, inclined-plane, and sealing is better; Prevented that dust from entering into universal joint assembly inside, simple and reasonable for structure.
