Double wheel milling wheel speed reducer

Abstract

The invention relates to a double wheel milling wheel speed reducer. The double wheel milling wheel speed reducer is composed of an input stage and a planetary gear pair, the input stage is composed of a spiral curved tooth bevel gear pair, the spiral curved tooth bevel gear pair forms first-stage transmission of the speed reducer, the planetary gear pair is a 2K-H planetary gear pair, and the planetary gear pair forms second, third and fourth-stage transmissions of the double wheel milling wheel speed reducer. The speed ratio of the fourth-stage transmissions of the speed reducer is reconfigured according to a priority number series, gear-cutting adjustment is made to the spiral bevel gear pair of the input stage, and the gap fixing mode between a supporting bearing and a gear shaft of a pinion gear of the spiral bevel gear pair, the third-stage speed ratio of the planetary gear pair and the connecting mode of a sun wheel and a transmission shaft are improved. By adoption of the speed reducer of the structure, fourth-stage speed ratio is more reasonably configured, the service life of the spiral curved tooth bevel gear pair is longer, the gap between the gear shaft of the bevel gear and the supporting bearing of the gear is fixed, and the normal working duration of the speed reducer is greatly prolonged.

Description

technical field [0001] The invention relates to the field of industrial production, in particular to the field of power transmission reducers for special equipment, in particular to a double-wheel milling wheel reducer. Background technique [0002] In recent years, the national blowout large-scale construction of new cities and their supporting municipal projects have achieved world-renowned results. However, the resulting disasters such as cities looking at the sea in the rainy season and ground subsidence have emerged endlessly. Recently, the pilot project of building a sponge city proposed by the relevant state departments has made the construction equipment of large continuous walls (up to 150 meters below the ground) into the priority ranks. And the equipment has been widely used in large subway stations, deep-water port terminals, major water conservancy projects and so on. [0003] At present, the double-wheel milling equipment is mainly imported from abroad. One of...

However, there are fatal errors in the parameters in the original information. By checking the actual objects, it can be found that the distribution of the transmission parameters of the reducer is extremely unreasonable, and the size chain control and transmission clearance cannot be guaranteed, which eventually leads to the failure of the reducer in a short time. cause huge losses
