Embodiment 1

[0055] Such as figure 1 As shown, a speed change mechanism includes two parallel and opposite first shaft systems, and the first shaft systems include several such as image 3 The transmission mechanism shown, the transmission mechanism includes such as Figure 4 Shown shaft 5, the sprocket 2 is set on the shaft 5, and the shaft 5 and the sprocket 2 are provided with Figure 5 The first connecting sleeve 6 shown, the shaft 5 and the first connecting sleeve 6, the first connecting sleeve 6 and the sprocket 2 are clearance fit, the shaft 5 and the first connecting sleeve 6, the first connecting sleeve 6 and the sprocket 2 They are all keyed connections; the two adjacent transmission mechanisms on the first shafting system are connected through such as Figure 6 The second connecting sleeve 7 shown is connected, the second connecting sleeve 7 and the shaft 5 are in clearance fit, and the second connecting sleeve 7 and the shaft 5 are in a key connection; the sprockets 2 on the ...

Embodiment 2

[0082] It differs from Embodiment 1 in that: as figure 2 As shown, the speed change mechanism also includes a second shaft system and a third shaft system, the second shaft system includes two transmission mechanisms, the two transmission mechanisms are connected through the second connecting sleeve 7, and the third shaft The system includes two transmission mechanisms, the two transmission mechanisms are connected through the second connecting sleeve 7, the second shaft system is respectively connected to one end of the two first shaft systems through two chains 1, and the third shaft system is connected through two chains 1 Connect the other ends of the two first shaft systems respectively.

[0083] In this embodiment, the second axis and the third shaft system serve as torque input and torque output respectively, and play a role in flexibly arranging the input and output shafts.

Abstract

The invention discloses a gear shifting mechanism which comprises two mutually parallel and opposite first shaft systems. The first shaft systems comprise a plurality of transmission mechanisms, the transmission mechanisms comprise shafts, chain wheels sleeve the shafts, a first connecting sleeve is arranged between each shaft and the corresponding chain wheel, the shafts are in clearance fit with the first connecting sleeves, the first connecting sleeves are in clearance fit with the chain wheels, the shafts are in key connection with the first connecting sleeves, the first connecting sleeves are in key connection with the chain wheels, every two adjacent transmission mechanisms on the first shaft systems are connected by a second connecting sleeve, the second connecting sleeves are in clearance fit with the shafts and are in key connection with the shafts, and the chain wheels on two first shaft systems are connected through a plurality of chains. The gear shifting mechanism is reasonable in design and convenient to manufacture and can solve the problems that an existing gear shifting mechanism is large in size, fewer in gears and high in manufacturing accuracy requirement.

Description

technical field [0001] The invention relates to the field of transmission equipment, in particular to a speed change mechanism. Background technique [0002] The existing parallel shaft gear transmission mechanism has the problems of large volume, small torque and few gears; at the same time, the existing planetary gear transmission mechanism has the problems of complex structure and high machining accuracy requirements. Contents of the invention [0003] In order to solve the above problems, the present invention provides a speed change mechanism. [0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows: a speed change mechanism includes two parallel and opposite first shaft systems, the first shaft system includes several transmission mechanisms, and the transmission mechanisms include shafts, A sprocket is set on the shaft, and a first connecting sleeve is arranged between the shaft and the sprocket. The shaft...
