Description
Technical field
The present invention relates to a kind of universal joint, particularly to a kind of Hooke's joint without needle roller.
Background technology
Existing microminiature universal joint mainly uses needle roller Hooke's joint, and it is short that this product is primarily present service life.Precision is low, noise is big and high rotating speed such as should not use at shortcoming and the problem.The reason caused: using needle-type universal joint subject matter is that needle roller diameter is little, with axle journal and set internal diameter contact surface little (simply linear contact lay), unit are load is big in use, cause Fast Wearing, accelerate the abrasion of axle journal needle bush internal diameter because of the powder after abrasion simultaneously, ultimately cause service life extremely short.Structure between axle journal and set internal diameter is complex simultaneously, and gap between the two is relatively big, and such structure is the compactest, the structural strength that impact is overall, and has the assembling arranging its product of needle roller more complicated.
The shortcoming existed for needle roller Hooke's joint, Patent No.: relate to a kind of Hooke's joint without needle roller in the mandate patent of invention of 200410056135.6, including cross axle and the overcoat being located at its spindle nose, the port part of overcoat arranges oil sealing, arranges the circular or soft wear resisting layer of cylinder cup-shaped between overcoat and cross axle.This invention hinge structure have needle roller Hooke's joint, it has simple in construction, the overall compact feature of easy to make, structure；But have the disadvantage in that
1, wearing layer is arranged between spindle nose and overcoat, and through long working at high speed, outer casing internal diameter certainly will be for having a certain degree of abrasion, can cause certain local pyrexia simultaneously；
2, this structure is high to the material requirements of overcoat；
3, this wearing layer is the most completely worn out, and universal joint then cannot normally work.
Summary of the invention
For not enough present in background technology, it is an object of the invention to a kind of Hooke's joint without needle roller, there is length in service life, feature that intensity is high, wear-resistant, can adapt to high intensity for a long time operates.
For achieving the above object, the technical scheme is that a kind of Hooke's joint without needle roller, including the spindle nose of cross axle and the outer female connector that is socketed with it, between spindle nose and outer female connector, wearing layer is set, socket root at spindle nose Yu outer female connector arranges sealing member, its spy is: described wearing layer is arranged on spindle nose surface, arrange between spindle nose and outer female connector and fix, with outer female connector internal diameter, the wear-resistant sleeve being connected, wear-resistant sleeve and spindle nose are rotatable matched in clearance, and coordinating between wear-resistant sleeve with spindle nose arranges at least one shoe cream room on face.
The present invention is further arranged to: arrange gap separation between described spindle nose end and outer female connector inner bottom surface.
The present invention is further arranged to: described shoe cream room is the oil storage hole being arranged on wear-resistant sleeve aperture surface.
The present invention is further arranged to: arrange shoe cream room in the gap between described spindle nose end and outer female connector inner bottom surface.
The present invention is further arranged to: the shoe cream room between described spindle nose end and outer female connector inner bottom surface is the oil storage tank being separately positioned on spindle nose end and outer female connector inner bottom surface.
The present invention is further arranged to: described wear-resistant sleeve is circular and is socketed on spindle nose external diameter surface.
The present invention is further arranged to: described outer female connector is fixedly connected as interference fit with wear-resistant sleeve.
The present invention is further arranged to: described outer female connector and sealing member cooperative end part arrange chamfering.
The present invention provides the benefit that compared to existing technology:
1. the present invention is by arranging the wear-resistant sleeve with outer female connector interference fit between spindle nose and outer female connector, wearing layer is set on spindle nose, the work process of universal joint is equivalent to the Relative friction motion between wear-resistant sleeve and wearing layer, oil storage hole is set on wear-resistant sleeve, certain lubricating oil is stored in oil storage hole, can reduce the frictional force between spindle nose and outer female connector, overall structure is greatly improved the wear-resisting intensity between spindle nose and outer female connector, enhances the service life of product；
2. reserved certain gap separation between end face and the bottom surface of extraneous set of the spindle nose of the present invention, the most do not coordinate contact, do not produce friction, the maximum overall friction decreased between spindle nose and outer female connector, simultaneously the end face at spindle nose is respectively provided with oil storage tank on the bottom surface of extraneous set, and the lubricating oil in oil storage tank is lubricated the supply of oil owing to the effect of centrifugal force is transferred to the contact surface of spindle nose and extraneous set during universal joint works；
3. the outer female connector of the present invention and sealing member cooperative end part arrange chamfering, it is simple to outside accessory assembling, play guide effect.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
Referring to figs. 1 through shown in Fig. 2, a kind of Hooke's joint without needle roller, including the spindle nose (3) of cross axle and the outer female connector (1) that is socketed with it, wearing layer (9) is set between spindle nose (3) and outer female connector (1), socket root at spindle nose (3) Yu outer female connector (1) arranges sealing member (4), wearing layer (9) is arranged on spindle nose (3) surface, arrange between spindle nose (3) and outer female connector (1) and fix the wear-resistant sleeve (2) being connected with outer female connector (1) internal diameter, wear-resistant sleeve (2) and spindle nose (3) are rotatable matched in clearance, coordinating between wear-resistant sleeve (2) with spindle nose (3) arranges at least one shoe cream room on face.Between spindle nose (3) end and outer female connector (1) inner bottom surface, gap separation is set.Shoe cream room is the oil storage hole (6) being arranged on wear-resistant sleeve (2) aperture surface.In gap between spindle nose (3) end and outer female connector (1) inner bottom surface, shoe cream room is set.Shoe cream room between spindle nose (3) end and outer female connector (1) inner bottom surface is to be separately positioned on the oil storage tank (5) on spindle nose (3) end and outer female connector (1) inner bottom surface and oil storage tank (7).Wear-resistant sleeve (2) is circular and is socketed on spindle nose (3) external diameter surface.Outer female connector (1) is fixedly connected as interference fit with wear-resistant sleeve (2).Outer female connector (1) and sealing member (4) cooperative end part arrange chamfering (8).
