Technical Field
The utility model relates to a mechanical frock technical field, more specifically relates to a railway traction motor drive gear surveys dress integration frock.
Background
The driving gear of the traction motor is one of the key parts of the electric locomotive running part for transmitting power, and the driving gear is in interference fit with the shaft of the traction motor in a conical shaft manner, so that the driving gear bears strong torque when the locomotive works under full load. If the driving gear of the locomotive is loosened or cracked during operation, the motor cannot output power; especially, under the working condition of low-speed heavy-load traction, the motor winding is burnt, and the driving safety of the locomotive is seriously influenced.
The loading amount of the driving gear of the traction motor of the S8 or S9 electric locomotive on the motor shaft is 1.6-2.2 mm (namely the gear loading amount), and the requirement on the installation accuracy is high. The mounting method adopted in the comparison document CN108274430A is based on a motor front end cover, which is a casting, and has a rough and uneven surface, and is not suitable for being used as an accurate measurement and mounting reference; secondly, the motor shaft rotates during installation, and thus, the two measurement references are inconsistent.
In addition, after the driving gear is taken out after being heated, the driving gear is influenced by various unstable factors such as environmental temperature, proficiency of operators and the like, and the expansion amount of an inner hole of the driving gear is uncertain even under the condition of complying with the standard maintenance process, so that the loading amount of the sleeved driving gear cannot be accurately and stably kept within the range of 1.6-2.2 mm.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome the unsafe defect of driving gear packing into volume among the above-mentioned prior art, provide a railway traction motor driving gear and survey dress integration frock, simple structure, simple to operate, position when can pinpoint driving gear cold charge, hot dress effectively improves the packing into volume of driving gear.
In order to solve the technical problem, the utility model discloses a technical scheme is: a railway traction motor driving gear testing and assembling integrated tool comprises a fastening sleeve, a positioning ring and a positioning sleeve; the positioning sleeve is provided with an axial second threaded hole corresponding to the first threaded hole in the end face of the motor shaft; the positioning ring is sleeved on the positioning sleeve, the positioning ring and the positioning sleeve are provided with limiting mechanisms, and the positioning ring can only move back and forth along the axial direction of the positioning sleeve; one end of the fastening sleeve is sleeved on the positioning sleeve, and the positioning ring can be driven to axially move along the positioning sleeve by rotating the fastening sleeve; and the positioning ring and the positioning sleeve are respectively provided with a scale mark for measuring the axial movement distance of the positioning ring and the tightening sleeve.
In the utility model, when the driving gear is installed, the driving gear is installed firstly in a cold-packed state, then the positioning sleeve is fixed on the end surface of the motor shaft through screws, and then the positioning ring and the tightening sleeve are sleeved on the positioning sleeve in sequence, and the tightening sleeve is rotated to push the positioning ring, so that the positioning ring is in close contact with the end surface of the driving gear, and the scales on the positioning ring and the positioning sleeve are recorded; then the fastening sleeve, the positioning ring and the driving gear are sequentially detached, the driving gear is heated and then installed on a motor shaft after being heated, the positioning ring and the fastening sleeve are sequentially sleeved, the fastening sleeve is rotated to push the positioning ring until the scales on the positioning ring and the positioning sleeve are consistent with those in a cold state, then the fastening sleeve is continuously rotated to ensure that the axial advancing displacement of the positioning ring is 1.6-2.2 mm, and at the moment, the driving gear also axially advances 1.6-2.2 mm under the pushing of the positioning ring; namely the loading amount of the driving gear in a hot loading state is 1.6 mm-2.2 mm; in cold-mounted and hot-mounted states, the positioning sleeve is not detached, the end face of the shaft of the traction motor is used as a measuring reference, the two references are consistent, and the rotation of the shaft of the traction motor cannot influence the measuring result because the positioning ring and the fastening sleeve can only move along the axial direction of the positioning sleeve; in addition, the positioning rings are only contacted with the end faces of the driving gears, and the axial expansion of the heated driving gears does not influence the loading amount of the driving gears; the initial position of the driving gear in a cold state is only a relative reference value relative to the whole installation process, and when the driving gear is hot-assembled, the positioning ring and the driving gear are pushed to advance by continuously rotating the tightening sleeve at the position, so that the final purpose is to ensure that the gear assembling amount is 1.6-2.2 mm; therefore the utility model provides an axial wearing and tearing of integration frock itself do not have the influence to the installation accuracy, have also effectively improved the installation accuracy of driving gear like this.
