Development of technology for repair of external balance bar of DT-75 tractor suspension carriage

1. The design examined the device, analysis of operation and characteristics of the main causes of loss of operability of the assembly unit. 2. A structural diagram of disassembly of the balancer of the external suspension carriage of the DT-75 tractor 3 has been developed. The part defect process has been developed. 4. The technological process of restoring defects of the external suspension carriage balancer of the DT-75 tractor was developed. During the course work, they studied the device and principle of operation of the external suspension carriage balancer of the DT-75 tractor, the characteristic of the main causes of the unit's loss of operability. They also presented a structural diagram of disassembly of the unit and developed a technological process for restoring and defective the part. We developed the necessary recovery routes for the part and determined the combination of defects in them. They chose rational ways to eliminate the main defects proposed by the teacher. They gave a brief characteristic of the defects and assigned methods of eliminating the defects according to the technological criterion. The assigned methods for elimination of defects were evaluated according to technical and technical-economic criteria. Developed Job Instructions for Part Recovery. They drew up a plan of operations for the process of restoring the part along the routes. They made a choice of technological equipment. The main process operation modes and technical normalization of these operations were calculated. Basic technological documentation was developed and presented .
