Abstract
The present invention relates to a structure improvement of a cross axle universal joint with no rolling needle and provides a cross axle universal joint with convenient manufacture, processing and assembly, light operation and small noise, which is suitable for high speed and low duty. A homogeneous and approximately isopachous soft wear-resistance layer with a circular ring shape or a circular cylinder cup shape is arranged between the outer ring and a cross axle head of the universal joint. The soft wear-resistance layer is formed by that nylon material is coated on the inner wall surface and the bottom surface of a cross axle. In a certain occasion, the soft wear-resistance layer is uniformly coated on the inner wall surface, the bottom surface and a grinding undercut between the inner wall surface and the bottom surface when an annular grinding undercut is obliquely arranged between the inner wall surface and the bottom surface of the outer ring. A position close to the basal portion of the cross axle head is provided with a circular groove, and the inner surface of the soft wear-resistance layer is fully filled in the circular groove. Therefore, the cross axle universal joint has the following characteristics of simple structure, convenient manufacture, compact structure, operation noise reduction, etc.; and the hardness of the axle head of the cross axle or the hardness of the inner surface of the outer ring is reduced. The technical scheme of the cross axle universal joint is the cross axle universal joint especially suitable for high speed and low duty.
Description
Technical field
The present invention relates to a kind of structure improvement of Hooke's joint, especially relate to a kind of compact structure, processing and assembling is convenient, a kind of Hooke's joint that does not have needle roller that performance strengthens.
Background technique
Existing Hooke's joint, the structure between its spindle nose end and the overcoat are comparatively complicated, and space between the two is very big, cause structure to owe compact, the structural strength that influence is whole like this.And, the making of needle roller, processing and assembling more complicated, and be easy to wearing and tearing, running noises is bigger.For example, the someone applied for a kind of universal joint patent (application number is: 87103541), a kind of universal joint, it is chewed with a butter and concentrates the filling oiling agent, it is evenly lubricated chronically to guarantee that all four rolling bearing positions can obtain.For this reason, in two mutually perpendicular passages of the cross axle of universal joint, two springs are housed.When not installing, the length of spring is greater than the axial dimension of passage.The two ends that the rear spring bar is installed lean on the interior edge face of corresponding bearing housing.This gimbal structure is comparatively complicated, and the middle spring that adopts makes that virtually it is loosely organized, and assembling difficulty is also bigger.Be easy to wearing and tearing when work, running noises is bigger, and inaccessible high-seal.Thereby, when work, be easy to produce oil leakage phenomenon, thereby cause the universal joint premature failure, shortened its working life, Economy is not high.
Summary of the invention
The present invention solves between the spindle nose of existing in prior technology Hooke's joint and the overcoat one directly to adopt the structure of needle roller and bring structure comparatively complicated, must leave the gap that is equal to or greater than the needle roller diameter between the two, cause structure to owe the technical problem of compactness etc., it is bigger directly to cause the diameter of the spindle nose of Hooke's joint to owe the overcoat diameter of big or Hooke's joint, the structural strength that influence is whole etc.
It is comparatively complicated that the present invention solves making, processing and the assembling of existing in prior technology needle roller again, and be easy to wearing and tearing, and running noises is bigger, the technical problem of poorly sealed grade.
The present invention has also solved the conventional universal joint of existing in prior technology simultaneously and has easily produced oil leakage phenomenon, thereby causes the technical problem of universal joint premature failure.Provide a kind of making, processing and assembling comparatively easy, move comparatively briskly, noise is less, is particularly useful at a high speed and the Hooke's joint of underloading.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of Hooke's joint that does not have needle roller, comprise cross axle and the overcoat of being located at its spindle nose, and be provided with oil sealing in the port part of overcoat, it is characterized in that between described overcoat and described cross-axis head, being provided with soft wear resisting layer circular or the cylinder cup-shaped.
As preferably, described soft wear resisting layer homogeneous and uniform thickness substantially, it is to adopt nylon material to be coated on the spindle nose periphery of cross axle and end face and constitute, and is provided with the soft wear resisting layer of being close on its chamfering that is connected between described periphery and end face.The nylon material here is extraordinary nylon.
As preferably, described soft wear resisting layer homogeneous and uniform thickness substantially, it is to adopt extraordinary nylon material to be coated on cross axle outer casing inner wall face and bottom surface and constitute.In certain occasion, when between the internal face of described overcoat and bottom surface, tiltedly being provided with the grinding undercut of annular, described soft wear resisting layer be coated with equably carries out reach therebetween grinding undercut in described internal face and bottom surface on.
As preferably, the average wall thickness of described soft wear resisting layer is 0.10mm-0.60mm.Usually, the coating wall thickness of described soft wear resisting layer depends primarily on the performances such as the strength of materials of coating, also depends on specification, magnitude of load and the running speed etc. of described Hooke's joint.
As preferably, the nearly base portion place of described cross-axis head is provided with annular slot, and the inner face of described soft wear resisting layer is filled and placed in it.Like this,,, make that this soft wear resisting layer is more firm, be difficult for tearing and durable in use because the edge of its inner opening is more abundant though that the outer surface of soft wear resisting layer still is is cylindric.
As preferably, the surface roughness parameter Ra of the shoe face that is coated with of described cross-axis head or overcoat is 0.8-3.6 μ m, makes full use of the adhesion and the elasticity of soft wear resisting layer, and it directly is coated on the cross-axis head that Vehicle Processing etc. makes.
In order to improve the performance of product, as preferably, the outer surface of described soft wear resisting layer is provided with ring-type or helical or netted convex tendon.
As another kind of scheme, as preferably, the outer surface of described soft wear resisting layer is provided with ring-type or helical or netted groove.
Therefore, the present invention has following characteristics: 1. and simple in structure, easy to make, can significantly reduce all operations or the inconvenience that bring because of make, assembling needle roller etc.; 2. structure is compact more, and traditional Hooke's joint is arranged that the space (gap) of needle roller is reduced to several to tens of silks, and this has created condition for the diameter that increases the cross axle spindle nose or the diameter that reduces overcoat; 3. avoided needle roller to contact and friction, reduced running noises significantly, made that operation is comparatively brisk with the direct of inside and outside metal surface; 4. need not to refuel or grease, do not have the leakage of oil problem; 5. can reduce the hardness requirement of cross axle spindle nose or overcoat inner face, be expected to become that a kind of novel exempting from refueled, non-maintaining Hooke's joint.Technological scheme of the present invention is particularly useful at a high speed and the Hooke's joint of underloading.
