Detailed Description

Referring to fig. 1, an engine 1 is a power output source of the whole system, and is directly connected with a CVT driving wheel 2 by a crankshaft, and then the CVT driving wheel 2 is connected with a CVT driven wheel 4 by a CVT belt 3, so that the whole CVT system performs power conversion on the engine power and realizes free switching of high and low torques. Before the installation of the driven wheel of the CVT, the UB205 spherical bearing 7 is installed on the left long shaft of the reverse gear box assembly 9, then the right driving shaft of the reverse gear box assembly 9 is installed in the bearing of the right large plate 11, wherein the 6205 bearing 10 is pressed into the right large plate 11 in advance, and after the reverse gear box assembly 9 is stably assembled, the UB205 spherical bearing 7 on the left long shaft can be installed and fastened with the left large plate 5. The CVT driven wheel 4 is connected with a spline of a left long shaft of the reverse gearbox assembly 9 in a mounting mode and can rotate along with the driven wheel. The rotating speed of the engine crankshaft is converted and output to the CVT driven wheel through the CVT system according to the torque, the CVT driven wheel drives the reverse gear box assembly long shaft to rotate, the rotating speed is reduced through two (forward/reverse) gear transmission ratios of the reverse gear box assembly, and the rotating speed output is transmitted to the driving chain wheel shaft on the right side of the reverse gear box.

The installation of the crawler driving system comprises the steps of pressing 6205 bearings 10 into the right side of a bearing seat assembly 27, pressing 35 multiplied by 47 multiplied by 725 oil seals into the left side of the bearing seat assembly, then installing a sealing bush assembly 26 into the right side of a driving shaft assembly 28, installing the assembled bearing seat assembly 27 into the right side of the driving shaft assembly 28, tightly adhering the sealing bush assembly 26 to the bearing seat assembly 27, then installing the driving shaft assembly 28 and the sealing bush assembly 26 on a bearing seat assembly 27 on a right large plate 11, pre-tightening the bearing seat assembly 27, installing UB205 spherical bearings 7 into the left side of the driving shaft assembly 28, then installing sensor induction sleeves 6 (for displaying instrument receiving speed) and fastening the sensor induction sleeves with bolts, and finally fastening the mounting bolts on the bearing seat assembly 27 and the mounting bolts on the UB205 spherical bearings 7.

A driving chain wheel shaft spline on the right side of a reverse gear box assembly 9 is sequentially provided with a lining 12, a driving chain wheel 13 and a lining II 14, wherein the driving chain wheel 13 and the driving chain wheel shaft are connected through an internal spline and an external spline and can rotate simultaneously, a tensioner 21 combination is arranged on a right large plate 11, a driven chain wheel 22 is arranged on the rightmost side of a driving shaft combination 28 and can rotate simultaneously through the spline connection, a tooth-shaped chain 23 of P9.525 is simultaneously sleeved in chain teeth of the driving chain wheel 13 and the driven chain wheel 22, the tensioner combination 21 is adjusted to tension the chain after the chain is arranged, and the driven chain wheel 22 is fastened, so that the rotating speed of the driving chain wheel shaft on the reverse gear box assembly can be transmitted to the driving shaft combination through the reduction of the driving chain wheel, the tooth-shaped chain and the driven chain wheel.

After the chain is assembled, 6005 bearing 15 and oil seal 32X 42X 717 are installed in chain transmission case 16, 24 sealing rubber ring is installed on the sealing boss of right large plate 11, and then the whole chain transmission case 16 is installed on right large plate 11 and fastened.
