Problems solved by technology

[0002] At present, the transmission gears commonly used in transmissions are all above three gears. For the two-speed transmissions required in equipment that only needs two gears to change gears, either the structure is complicated or the reliability is low. The technical cost required for a two-speed transmission is very high, so it is necessary to design a transmission with only two gears

specific Embodiment approach

[0044]Specific embodiments: when people use the transmission designed by the present invention, when the input shaft 6 rotates, the input shaft 6 rotates to drive the drive plate 20 to rotate around the axis of the input shaft 6, and the drive plate 20 rotates to drive the arc bar 21 to rotate. When the rotation speed of the arc bar 21 is small, the centrifugal block is less affected by the centrifugal force, and the arc bar 21 and the fixed shaft disc 18 are still in a clamped state, and the arc bar 21 will drive the fixed shaft disc 18 to rotate; the fixed shaft disc 18 drives the third fixed shaft 19 to rotate, and the third fixed shaft 19 rotates through the second one-way ring 15 to drive the second sun gear 17 to rotate; the second sun gear 17 rotates to drive the second planetary gear 10 to rotate; the second planetary gear 10 rotates Drive the inner ring gear 4 to rotate; the inner ring gear 4 drives the output shaft 13 to rotate; that is, the rotation of the input shaf...

Abstract

The invention belongs to the technical field of speed changers, and particularly relates to a two-gear speed changer. The two-gear speed changer comprises an installing plate, a drum, an input shaft,a Z-shaped ring and an output shaft. When the input shaft rotates, a drive plate drives an arc strip to rotate, and when the rotation speed of the arc strip is small, the action from centrifugal forceto a centrifugal block is weak, the arc strip can drive a fixing shaft disc to rotate, and a third fixing shaft, a second one-way ring, a second sun gear and a second planet gear rotate and drive aninner gear ring to rotate. The inner gear ring drives the output shaft to rotate. When the arc strip moves at a high speed and a first centrifugal block makes contact with the drum in the motion process, the first centrifugal block can rub with the drum, the arc strip drives the drum to rotate through friction between the first centrifugal block and the drum, a Z-shaped wheel rotates and drives the first sun gear to rotate through the first one-way ring, and the first planet gear drives the inner gear ring to rotate; the inner gear ring drives the output shaft to rotate; and the beneficial effect of two-gear transmission is achieved through a simple structure.

Description

technical field [0001] The invention belongs to the technical field of transmissions, in particular to a two-speed transmission. Background technique [0002] At present, the transmission gears commonly used in transmissions are all above three gears. For the two-speed transmissions required in equipment that only needs two gears to change gears, either the structure is complicated or the reliability is low. The technical cost required for the two-speed transmission is very high, so it is necessary to design a transmission with only two gears. [0003] The present invention designs a two-speed transmission to solve the above problems. Contents of the invention [0004] In order to solve the above-mentioned defects in the prior art, the present invention discloses a two-speed transmission, which is realized by adopting the following technical solutions. [0005] A two-speed transmission, characterized in that it includes a mounting plate, a fixed cylinder, a fixed ring, a...
