Problems solved by technology

[0004] However, the utilization rate of lubricating oil in the above-mentioned lubrication method is not high. Since the speed of the multi-stage planetary gear near the input end is fast, the loss of lubricating oil is relatively large, while the speed of the gear near the output end is relatively slow, resulting in a loss of lubricating oil. However, when the end with a faster speed wears and generates heat, it will pollute the lubricating oil, and technicians can only replace the lubricating oil in the reducer

Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0030] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordi...

Abstract

The invention relates to the technical field of speed reducers, in particular to a planetary speed reduction lubricating system which comprises a planetary reducer, a filter and an oil pump. The planetary reducer is provided with an oil inlet connector connected with an oil inlet and an oil outlet connector connected with an oil outlet. An outlet of the filter is connected with the oil inlet connector. One end of the oil pump is connected with the oil outlet connector, and the other end of the oil pump is connected with an inlet of the filter and used for conveying lubricating oil discharged from the planetary reducer into the filter. According to the planetary reducer, an oil baffles are arranged in a multi-stage step type containing cavities of the planetary reducer, so that lubricatingoil is distributed in a stepped shape at all stages of gears, and compared with the prior art, the using amount of the lubricating oil is reduced; and moreover, the oil inlet is formed in the first cavity, and the oil outlet is formed in the third cavity, so that a flowing lubricating system from the power input end to the power output end is formed, and the utilization rate of the lubricating oilis increased. The invention further requests to protect the planetary reducer.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a planetary reducer and a lubrication system thereof. Background technique [0002] Planetary reducer is an industrial product, its structure is composed of main components such as sun gear, planetary gear set, ring gear and planet carrier, the sun gear is connected with the input device, the sun gear is set at the center of the ring gear, and the planetary gear set is set There are at least three uniformly distributed between the sun gear and the ring gear, and the planet carrier is an output member connected with the planetary gear set; in order to adjust the transmission ratio, multiple sets of planetary gear structures can be set along the axial direction of the sun gear, in order to achieve more For the adjustment of large transmission ratio, the size of the inner ring gear of multiple sets of planetary gears is often set gradually. When the planetary gear reducer is placed...
