Abstract
The invention discloses a speed reducer shell, which comprises a box body and a cover body. The bottom part of the cover body is fastened to the top part of the box body in a covering way; a circle of first flange is arranged on the top part of the box body; a circle of second flange is arranged at a corresponding matched position of the bottom part of the cover body; a circle of groove is formed in the first flange; a circle of boss with the shape being matched with the groove is arranged on the second flange; and the cover body is connected with the groove in the first flange through the boss on the second flange in an inserting way. Compared with the prior art, according to the speed reducer shell provided by the invention, a shell structure is reasonably designed, the complexity of an oil circuit at a leakage part is increased, and a sealing gasket is coordinately used for effectively blocking lubricating oil in the groove, so that the oil leakage phenomenon of a bonding surface of the box body and the cover body is prevented, an oil leakage prevention effect is greatly improved, and the service life of a speed reducer is prolonged. Therefore, the speed reducer shell has a wide application prospect.
Description
Technical field
It is to be related to a kind of speed reducer housing specifically the present invention relates to a kind of shell, belongs to mechanical equipment technical field.
Background technology
Decelerator is generally used between prime mover, working machine or executing agency and plays matching rotating speed and transmission torque, and output torque is improved while rotating speed is reduced, and is a kind of relatively accurate gearing, using extremely wide in modern mechanical field.
But, because retarder operation environment is generally relatively more severe, during continuously running, influenceed by friction in pairs heating and environment temperature, so that temperature is raised in reduction-gear housing body, pressure gradually increases, and also increases therewith with extraneous pressure differential, cause the lubricating oil in casing because differential pressure action is revealed from the faying face gap of casing and lid, have a strong impact on the service life of decelerator.For this leakage problem, maintenance personal generally needs dismounting decelerator and gasket seal or fluid sealant to deformation failure are changed, and not only wastes time and energy, deficiency in economic performance, and be difficult to ensure that sealing effectiveness, once oil circuit is formed, can also again occur oil leakage phenomenon during follow-up use.Therefore, a kind of reasonable in design, leak preventing effect are good and speed reducer housing of long service life is urgently released.
The content of the invention
In view of the above-mentioned problems existing in the prior art, it is an object of the invention to provide a kind of speed reducer housing, by the structure of reasonable designed enclosures, casing and lid faying face oil leakage phenomenon, effectively lifting oil-leakage-prevention effect, the service life of increase decelerator are solved.
For achieving the above object, the technical solution adopted by the present invention is as follows：
A kind of speed reducer housing, including casing and lid, the bottom cover of lid is buckled in casing top, wherein, casing top is provided with first flange of circle, and second flange of circle is provided with the corresponding cooperation position of lid bottom, and a circle groove is provided with the first flange, second flange is provided with the boss of a loop-shaped and groove match, and lid is by the groove grafting on the boss and the flange of casing first on the second flange.
Preferably, it is contemplated that the processing characteristics and shock-absorbing performance of speed reducer housing, the material selection cast iron of shell.
Preferably, the shape of cross section of groove is triangle or rectangle, and convenient processing and manufacturing reduces processing cost.
Preferably, in order to improve the oil-leakage-prevention performance of decelerator, sealing gasket is additionally provided with groove.
It is highly preferred that sealing gasket elects the good rubber gasket of oil-leakage-prevention performance as.
Preferably, more oil change for convenience, bottom half is additionally provided with an outage, and matching has a dismountable port lid on outage.
Preferably, decelerator is carried and lifted for convenience, and at least one hanger is provided with lid.
It is highly preferred that lid two ends are provided with two hangers, balance is kept when being conducive to decelerator to lift, be easy to control and install.
Preferably, operating personnel check abnormal in decelerator for convenience, and a rectangular sight openings are also provided with lid, and accordingly, matching has a cover plate on observation panel.
Relative to prior art, the beneficial effects of the invention are as follows：By reasonable designed enclosures structure, the complexity of oil circuit at leakage is increased, cooperateed with sealing gasket and used, effectively lubrication oil seal can be locked in groove, so as to solve casing and lid faying face oil leakage phenomenon, oil-leakage-prevention effect is greatly improved, extend the service life of decelerator.Therefore, with very wide application prospect and promotional value.
