Abstract

The invention discloses a two-gear big-speed-difference speed changer which mainly consists of an input shaft, a primary sun wheel, a primary planet wheel, a primary planet carrier, an inner toothed ring, a secondary planet wheel, a secondary sun wheel, a secondary planet carrier and a gear shifting control mechanism; the input shaft is connected with a motor or a hydraulic motor; the input shaft is engaged with the primary planet wheel arranged on the primary planet carrier through the fixedly connected primary sun wheel; the primary planet wheel is connected with the secondary planet wheel by sharing the inner toothed ring; the primary planet carrier is fixedly connected with the secondary sun wheel; the secondary sun wheel is engaged with the secondary planet wheel sleeving the secondary planet carrier; the secondary planet carrier is in flange connection with an output shaft; the gear shifting control mechanism comprises a control toothed shaft connected with the inner toothed ring, a toothed seat connected with a housing, a sliding toothed sleeve, a toothed seat connected with the output shaft, and an output flange; the inner toothed ring is connected with a control toothed seat; the control toothed seat is connected with the sliding toothed sleeve; and through the sliding toothed sleeve, one side of the control toothed seat is placed on the toothed seat connected with the housing, and the other side of the control toothed seat is placed on the toothed seat connected with the secondary planet carrier.

Description

technical field [0001] The invention relates to a second-gear transmission, especially a transmission with a particularly large second-gear speed difference, and belongs to the technical field of mechanical transmission. Background technique [0002] In the prior art, the second-speed transmission is a relatively mature technology. According to different needs, the structure of the second-speed transmission is somewhat different due to different shifting modes, but most of the structures are the same or similar. However, for applications requiring a large speed difference, the existing second-speed transmission is difficult to meet the actual needs. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings, and provide a second-speed transmission with a large differential speed with simple and compact structure, small size, light weight, advanced technical indicators, reliable use, convenient installation and ma...
