Embodiment Construction

[0018] See Figure 1-3 , The embodiment of the present invention provides an adaptive lubrication structure for a reducer, which is connected to a hydraulic oil pump to lubricate the primary planet carrier 2 and the secondary planet carrier. The adaptive lubrication structure includes: a primary planetary gear lubrication device and Secondary planetary gear lubrication device.

[0019] The first-stage planetary gear lubrication device includes: an oil inlet mechanism, an oil guide bracket 1, a support bearing 11, a pre-tensioning mechanism, and an oil return mechanism. One end of the oil inlet mechanism is in communication with the hydraulic oil pump, and the other end is connected with the guide The oil support 1 is in communication, one end of the oil guide support 1 is in contact with the end surface of the first stage planet carrier 2, the oil guide support 1 is provided with an annular oil groove 1-1, and one end of the pre-tensioning mechanism is connected to the oil guide ...

Abstract

The invention discloses a self-adaptive lubrication structure and method for speed reducers, and belongs to the technical field of the speed reducers. The self-adaptive lubrication structure for the speed reducers comprises a first-stage planet wheel lubrication device and a second-stage planet wheel lubrication device; the first-stage planet wheel lubrication device comprises an oil inlet mechanism, an oil guide support, a supporting bearing, a pre-tightening mechanism and an oil return mechanism, wherein one end of the oil inlet mechanism is communicated with a hydraulic oil pump, the other end of the oil inlet mechanism is communicated with the oil guide support, the oil guide support is provided with an annular oil groove, one end of the pre-tightening mechanism is connected to the oil guide support, the other end of the pre-tightening mechanism is connected to the supporting bearing, and the oil return mechanism is arranged below the oil guide support; one end of the second-stage planet wheel lubrication device is communicated with the hydraulic oil pump, and the other end of the second-stage planet wheel lubrication device is communicated with a second-stage planet carrier. According to the self-adaptive lubrication structure for the speed reducers, multi-point oil supply and lubrication is realized, redundant oil overflows and directly flows into the oil return pipe from under for adapting to the change of the quantity of the oil, and the lubrication oil is continuous and reliable.

Description

Technical field [0001] The invention relates to the technical field of speed reducers, in particular to an adaptive lubrication structure and method for speed reducers. Background technique [0002] Due to the large tonnage and long transportation distance of the reducer on large and heavy engineering equipment, the reducer generally has a large heat problem. Therefore, the reducer on the large-tonnage mine truck is generally equipped with an independent heat dissipation and lubrication system. The existing lubrication system generally uses a lubricating oil pipeline to directly connect to the first and second planetary gears, and the gears are lubricated by the oil splashing and agitation after the hydraulic pump is filled with oil. However, after adopting the above scheme in the prior art, there are the following problems in practical application: 1. There are few lubrication points, and only one oil pipe is used for oil injection lubrication, resulting in unsatisfactory lubric...
