Abstract
The utility model relates to the structural improvement of a crossing pin type universal joint without rolling needle, providing the crossing pin type universal joint which has easy manufacture, process and assembly, light operation and small noise, and the crossing pin type universal joint is particularly suitable for high speed and light load. A circular-ring shaped or circular column cup-shaped homogeneous and basically isopachous soft wear-resistant layer is arranged between the outer ring of the universal joint and the cross pin head. The soft wear-resistant layer is formed by that the nylon material is coated at the inner wall surface and the bottom surface of the outer ring of the cross pin. When an annular grinding undercut is arranged obliquely between the inner wall surface and the bottom surface of the outer ring, the soft wear-resistant layer is coated on the inner wall surface, the bottom surface and the grinding undercut between the inner wall surface and the bottom surface. An annular groove is arranged at the near root part of the cross pin head, and the annular groove is filled with the inner face of the soft wear-resistant layer. The utility model has the advantages of simple and compact structure and easy manufacture, reduced operation noise, and reduced hardness requirement of the pin head of the cross pin or the inner face of the outer ring, etc.
Description
Technical field
The utility model relates to a kind of structure improvement of Hooke's joint, especially relates to a kind of compact structure, and 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 outer ring 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.
The model utility content
The utility model mainly is to solve between the spindle nose of existing in prior technology Hooke's joint and the outer ring 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 race diameter of big or Hooke's joint, the structural strength that influence is whole etc.
Making, processing and the assembling that the utility model also solves the existing in prior technology needle roller simultaneously is comparatively complicated, and is easy to wearing and tearing, and running noises is bigger, and is poorly sealed, makes the universal joint leakage of oil, thereby causes the technical problem of universal joint premature failure etc.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 utility model is mainly solved by following technical proposals: a kind of Hooke's joint that does not have needle roller, comprise cross axle and the outer ring of being located at its spindle nose, and be provided with oil sealing in the port part of outer ring, it is characterized in that between described outer ring and described cross-axis head, being provided with the homogeneous and the soft wear resisting layer of the circular or cylinder cup-shaped of uniform thickness substantially.
As preferably, described soft wear resisting layer system adopts nylon material to be coated on the spindle nose periphery of cross axle and end face and constitutes, 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 system adopts extraordinary nylon material to be coated on cross axle outer ring internal face and bottom surface and constitutes.In certain occasion, when between the internal face of described outer ring 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 outer ring 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 utlity model has following characteristics: 1. 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 the outer ring; 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 outer ring inner face, be expected to become that a kind of novel exempting from refueled, non-maintaining Hooke's joint.The technical solution of the utility model is particularly useful at a high speed and the Hooke's joint of underloading.
