Abstract
The utility model relates to a cross axle universal joint with an oil storing cavity, which comprises a cross axle, wherein the middle part of the cross axle is provided with an oil storing cavity which is provided with a cover plate, the cover plate is provided with an oil plug hole, the axle head end of the cross axle is provided with an oil cup, an oil passage which is in the shape like the Chinese character 'mi' and an oil filling hole are arranged at the inner part of the cross axle, and the oil passage is communicated with the oil filling hole; thus, the structure has the characteristics of large oil storing quantity, sufficient oil supply and smooth oil passages. Simultaneously, the oil passage which is in the shape like the Chinese character 'mi' enables the oil supplying direction to be multiple directions. The utility model is particularly suitable for being used in the operating environment that large and middle universal joints are inconveniently assembled and disassembled, and has the characteristics of reliable performance, simple structure, reasonable structure and novelty.
Description
Technical field
The utility model relates to a kind of Hooke's joint, especially relates to a kind of Hooke's joint that is provided with shoe cream room.
Background technique
Universal joint occupies crucial status in modern industry production, because its function has determined that the lubricated of universal joint is the basis that guarantees its proper functioning, very important with storage for the injection of the lubricant oil of universal joint thus.For example, a kind of " universal joint of non-return oil storage " patent application (03230904.X) by name, this universal joint comprises cross axle, shafting oil envelope and bearing outside are set on cross axle and are arranged on therebetween needle roller, and lubricating cup is offered in the spindle nose end at described cross axle, the oil duct of setting and described lubricating cup conducting in the cross axle, and in described lubricating cup, oil retainer is set.The oil retainer middle part is provided with baffle ring, and inside is provided with through hole, and its two ends are spindle, and average diameter is slightly larger than the internal diameter of described oil duct.But the oil reserve of this structure is subjected to the restriction of cross axle oil duct diameter specifications, thereby has limited the oil reserve of universal joint; And the oiling direction of universal joint is single, is not suitable for carrying out a plurality of direction oilings at some special environment.
Summary of the invention
It is a kind of simple in structure, reasonable in design that the utility model provides, and can effectively solve the Hooke's joint that carries out multi-direction oiling in particular surroundings; Solve the limited problem of storage oil mass that exists in the prior art.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of Hooke's joint that is provided with shoe cream room, comprise cross axle, the cross axle spindle nose is provided with shafting oil envelope and bearing outside and is arranged on therebetween needle roller, be provided with oil duct in the cross axle, it is characterized in that: be provided with shoe cream room at the cross axle middle part, shoe cream room is provided with cover plate, and shoe cream room links to each other with oil duct.Owing to shoe cream room is set at the cross axle middle part, oil storage space is increased significantly, thus lubricated more abundant.
As preferably, between described cross axle spindle nose oil hole is set, oil hole communicates with oil duct, and passage distributes and is " rice " word shape; Oil hole also links to each other with shoe cream room simultaneously.Oil hole has one at least, because the offering of oil hole, makes the oiling direction can be more flexible, can multi-direction oiling.
As preferably, described cover plate is provided with the plug cock hole of matching with plug cock, and plug cock adopts screw-thread fit to connect with cover plate, and the distance between any two holes is greater than the diameter of plug cock bolt head.Plug cock adopts engage thread to connect, and is in order to increase the oiling mode, can well to seal simultaneously, being easy to dismounting.
Cover plate and plug cock can also adopt modes such as riveted joint or interference fit simultaneously, can reach the effect of better sealing like this, omit technology.
As preferably, the spindle nose end of described cross axle is provided with lubricating cup, and the oil duct with described lubricating cup conducting is set in the cross axle, and oil duct links to each other with shoe cream room.This structure all is connected on the shoe cream room each oil duct, and oil duct is smooth and easy, thereby lubricant oil can effectively be distributed on each spindle nose, is beneficial to lubricated.
As preferably, the shoe cream room on the described cross axle is frustoconic shape.This structure is easy to processing, and technology capability is good simultaneously.
As preferably, described side edge thereof is provided with screw thread, and with the shoe cream room port threads engaged of cross axle.By scyewed joint, reach the function of sealing.
Therefore, it is big to the utlity model has oil reserve, multidirectionalization of oiling direction, and oil circuit is unobstructed, is beneficial to advantages such as lubricated, and is specially adapted to have reliable performance, simple and reasonable for structure, novel features in the inconvenient working environment of big-and-middle-sized universal joint mounting or dismounting.
Description of drawings:
Accompanying drawing 1 is the plan view of Hooke's joint structure of the present utility model;
Accompanying drawing 2 is side view cutaway drawings of Hooke's joint structure of the present utility model;
Accompanying drawing 3 is overall schematic of original Hooke's joint;
Accompanying drawing 4 is side view cutaway drawings of original Hooke's joint.
The concrete example of implementing:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Shown in accompanying drawing 1 or 2, be provided with the Hooke's joint of shoe cream room, its main body is exactly a cross axle 1, be provided with lubricating cup 6 at cross axle spindle nose end, be provided with oil duct 5 and oil hole 7 that " rice " font communicates in cross axle 1 inside, lubricant oil can be flowed very smoothly, thereby lubrication effect be better; Be provided with shoe cream room 4 at cross axle 1 middle part, shoe cream room 4 is round table-like, and the setting of shoe cream room 4 has overcome owing to the restriction that is subjected to oil duct 5 diameters, thereby the little shortcoming of oil reserve makes universal energy-conservation more lasting work.
Shoe cream room 4 ports adopt screw thread to cooperate with cover plate 2, thereby reach sealing effect; Be processed with simultaneously the plug cock hole on cover plate 2, plug cock 3 also is to adopt thread seal to cooperate with cover plate 2, so promptly makes things convenient for oiling, also is convenient to install.
