Description

A kind of bearing support of high temperature coal-tar pump
Technical field
The utility model relates to the bearing support of oil pump, is specifically related to a kind of bearing support of high temperature coal-tar pump.
Background technique
The bearing block structure of current market high temperature coal-tar pump only has upper design to have oil hole, for bearing and the oil sealing lubricant oil of annotating, and lubricant oil needs periodic replacement just can guarantee the normal operation of bearing and not damage, more pump head all must be taken apart during oil change, bother very much, if do not carry out taking more oil change apart, the working life of bearing can be reduced.As adopted the drain oil directly in bearing block structure bottom to install plug, due to more oil change frequently, easily causing the drain oil internal thread slide fastener of bearing support, causing bearing support to scrap, increase burden to client.
Model utility content
For the problems referred to above, technical problem to be solved in the utility model is to provide a kind of can repeatedly use and the bearing support of the low high temperature coal-tar pump of maintenance rate.
The utility model adopts following technological scheme:
The right bearing hole that the utility model comprises the axis hole be sleeved on pump shaft, be separately positioned on the left bearing hole of the axis hole left and right sides and right oil sealing hole and be arranged on the right side of right oil sealing hole, the upper side wall of described axis hole is provided with oil hole, described oil hole, with closely-pitched internal thread, is provided with drain oil in the lower wall of described axis hole; Between pump shaft and left bearing hole, be provided with bearing A, between pump shaft and right oil sealing hole, be provided with oil sealing, between pump shaft and right bearing hole, be provided with bearing B; The spacer shell be provided with in described drain oil, is provided with transition internal thread in described spacer shell, and described transition internal thread is fine thread, in described transition internal thread, be provided with plug; Be provided with positioning filament hole described drain oil lower end outside is uniform, described transition internal thread outer side wall top is provided with transition outside thread, the internal thread be connected with transition outside thread is provided with in described drain oil, be provided with the connecting filament hole corresponding with described positioning filament hole described transition internal thread outer side wall bottom is uniform, described positioning filament hole and connecting filament hole are connected by screw.
The beneficial effects of the utility model are as follows:
The utility model is provided with drain oil in bearing support bottom, in drain oil, sealing is provided with spacer shell, in spacer shell, sealing is provided with plug, spacer shell is fixedly mounted on bearing support by screw, more during oil change, only need turn on plug bleeds off old lubricant oil, then plug is tightened, to annotate new lubricant oil from tank filler sleeve again, easy and simple to handle, after oil pump uses a period of time, when spacer shell occurs that slide fastener can not continue to use, by screw disassembling, spacer shell is pulled down, the spacer shell more renewed, whole bearing support is not needed to pull down, thus reduce the maintenance rate of equipment, improve the working life of bearing support, the utility model compact structure, be applicable to large-scale promotion.
