The utility model provides a two oil blanket are arranged and are covered thoroughly, passes through two skeleton oil blanket between covering inner wall and the play axle including setting up in the speed reducer, its characterized in that: the two framework oil seals are arranged in parallel, a gap for forming an outer oil seal lubricating cavity is reserved between the two framework oil seals, an oil inlet channel is arranged at the upper part of the through cover, an outer opening of the oil inlet channel is connected with an oil cup through an oil nozzle, an inner opening of the oil inlet channel is communicated with the outer oil seal lubricating cavity, an oil return channel is arranged at the lower part of the through cover, and the oil return channel is communicated with the outer oil seal lubricating cavity and the inner cavity of the speed reducer box; and a plurality of circles of baffle ring plates or a circle of baffle ring plate with a spiral structure which is not in contact with the output shaft is arranged on the inner wall of the transparent cover corresponding to the lubricating cavity of the outer oil seal.

Technical Field

The invention relates to a speed reducer, in particular to a double-oil-seal arrangement transparent cover of the speed reducer.

Background

The traditional through cover penetrating shaft is usually provided with more than two oil seals for preventing internal lubricating oil from leaking, but because the first oil seal is sealed, the second oil seal is basically free of lubricating oil and is in a dry friction state for a long time, and the leakage is easily caused after the wear.

Disclosure of Invention

The double-oil-seal arrangement transparent cover provided by the invention has a simple and compact structure, can effectively lubricate double oil seals, and avoids the influence of excessive abrasion of the external oil seal on the use performance.

The technical scheme adopted by the invention is as follows: the utility model provides a two oil blanket are arranged and are covered thoroughly, passes through two skeleton oil blanket between covering inner wall and the play axle including setting up in the speed reducer, its characterized in that: the two framework oil seals are arranged in parallel, a gap for forming an outer oil seal lubricating cavity is reserved between the two framework oil seals, an oil inlet channel is arranged at the upper part of the through cover, an outer opening of the oil inlet channel is connected with an oil cup through an oil nozzle, an inner opening of the oil inlet channel is communicated with the outer oil seal lubricating cavity, an oil return channel is arranged at the lower part of the through cover, and the oil return channel is communicated with the outer oil seal lubricating cavity and the inner cavity of the speed reducer box; and a plurality of circles of baffle ring plates or a circle of baffle ring plate with a spiral structure which is not in contact with the output shaft is arranged on the inner wall of the transparent cover corresponding to the lubricating cavity of the outer oil seal.

An outer oil seal lubricating cavity is reserved between the two framework oil seals, an oil cup supplies oil to an outer oil seal lubricating oil cavity through oil injection of an oil nozzle through an oil inlet channel on the upper part of the transparent cover, lubricating oil is limited and effectively supplied to and lubricated by a second framework oil seal positioned outside in the outer oil seal lubricating oil cavity, lubricating oil leakage caused by excessive abrasion in long-term use is avoided, and the lubricating oil in the outer oil seal lubricating cavity returns to the inner cavity of a speed reducer box body through an oil return channel; the inner wall of the transparent cover corresponding to the lubricating oil of the outer oil seal is provided with a plurality of circles of baffle ring plates or a circle of baffle ring plate with a spiral structure, which are not in contact with the output shaft, so that the detention time of the lubricating oil in the lubricating cavity of the outer oil seal can be prolonged, and the oil supply amount of an oil cup is reduced while the lubricating effect is taken into consideration.

Drawings

FIG. 1 is a schematic view of the structure of the present invention.

In the figure: the oil seal structure comprises a transparent cover 1, an output shaft 2, a first framework oil seal 3, a second framework oil seal 4, an outer oil seal lubricating cavity 5, a baffle ring plate 6, an oil inlet channel 7, an oil nozzle 8, an oil cup 9 and an oil return channel 10.

Detailed Description

The following further description is made in conjunction with the accompanying drawings and examples.

Fig. 1 shows, a two oil seals arrange and pass through lid, including passing through lid 1, first skeleton oil blanket 3, second skeleton oil blanket 4, outer oil blanket lubrication cavity 5, fender ring board 6, oil feed passageway 7, fuel sprayer 8, oil cup 9, oil return passageway 10. The first and second framework oil seals 3 and 4 are arranged in parallel from inside to outside between the inner wall of a transparent cover 1 of the speed reducer and an output shaft 2, and a gap for forming an outer oil seal lubricating cavity 5 is reserved between the inner wall and the output shaft 2; and a plurality of circles of baffle ring plates or a circle of baffle ring plate 6 with a spiral structure which is not in contact with the output shaft is arranged on the inner wall of the transparent cover corresponding to the outer oil seal lubricating cavity 5.
