Abstract
The utility model relates to a device for mounting and dismounting a thrust bearing of an oil transfer pump, in particular to a device for quickly mounting and dismounting a thrust bearing of an oil transfer pump. A threaded connection screw thread is arranged on the periphery of an auxiliary shaft; the auxiliary shaft is connected with a pump shaft of the oil transfer pump in a co-radial way; one end of the auxiliary shaft is provided with an auxiliary shaft fastening hole, and the other end of the auxiliary shaft is connected with the end part of the pump shaft through locking threads; and a stress application rod is inserted into the auxiliary shaft fastening hole to screw the threaded connection screw thread of the auxiliary shaft. When the thrust bearing is mounted or dismounted, the auxiliary shaft is screwed in the thrust bearing so as to be connected with the end part of the pump shaft through locking threads; the stress application rod is inserted into the auxiliary shaft fastening hole to screw the threaded connection screw thread of the auxiliary shaft; and after the operation is finished, the auxiliary shaft is mounted or dismounted. The device has the effects of simple structure and operation, convenience for mounting, dismounting and maintaining, prevention of mechanical injury and shock, co-radial shaft connection, time and labor saving and high working efficiency for mounting, dismounting and maintaining, and is widely used as a device/tool for mounting and dismounting the thrust bearing of the oil transfer pump.
Description
Technical field
The utility model relates to a kind of oil transfer pump thrust bearing installing/dismounting device, particularly fast to oil transfer pump thrust bearing installing/dismounting appliance arrangement.
Background technology
At present, in the maintenance of oil and gas pipeline oil transfer pump, there is not a kind of proper tools that the thrust bearing assembly is installed, in original maintenance process, because the thrust bearing assembly is in bearing bore, taking-up and assembling all need to visit hand and enter, when taking out, can produce damage such as collide with, in assembling process, owing to the contraposition reason to the thrust bearing assembly, repeatedly install not in place, moreover thrust bearing assembly weight is big, and there is greatly potential safety hazard in artificial assembling.
Summary of the invention
The purpose of this utility model, provide a kind of oil transfer pump thrust bearing installing/dismounting device, it is to adopt the be threaded pump shaft end locking screw of screw thread and oil transfer pump of asessory shaft to interconnect, boosting-rod inserted in the asessory shaft fastener hole be tightened, carry out installing/dismounting oil transfer pump thrust bearing, realize quick purpose oil transfer pump thrust bearing installing/dismounting device.
The utility model oil transfer pump thrust bearing installing/dismounting device takes following technical scheme to realize, it is to be made of asessory shaft and be threaded screw thread and asessory shaft fastener hole, the asessory shaft periphery setting screw thread that is threaded, asessory shaft is connected with the footpath with the pump shaft of oil transfer pump, one end of asessory shaft is provided with the asessory shaft fastener hole, the other end of asessory shaft is connected with pump shaft end locking screw, and boosting-rod inserts and to screw the asessory shaft screw thread that is threaded in the asessory shaft fastener hole.Install or during the dismounting thrust bearing, asessory shaft is screwed in the thrust bearing is connected, adopt boosting-rod to insert to screw in the asessory shaft fastener hole asessory shaft screw thread that is threaded, after operation finishes, with the asessory shaft installation or disassemble with pump shaft end locking screw.
The effect of the utility model oil transfer pump thrust bearing installing/dismounting device is simple in structure, installing/dismounting is easy to maintenance, simple to operate, prevent mechanical wounding and percussion, connect with the footpath axle, boosting-rod inserts to screw in the asessory shaft fastener hole and gets final product, and is time saving and energy saving, installing/dismounting maintenance work efficient height is widely used in the installing/dismounting device instrument of oil transfer pump thrust bearing.
Description of drawings
The utility model oil transfer pump thrust bearing installing/dismounting device will describe in further detail in conjunction with the accompanying drawings.
Accompanying drawing is the structural representation of the utility model oil transfer pump thrust bearing installing/dismounting device.
1-asessory shaft 2-screw thread 3-asessory shaft fastener hole is threaded.
The specific embodiment
With reference to accompanying drawing, the utility model oil transfer pump thrust bearing installing/dismounting device, it is to be made of with asessory shaft fastener hole 3 asessory shaft 1 and the screw thread 2 that is threaded, the asessory shaft 1 periphery setting screw thread 2 that is threaded, asessory shaft 1 is connected with the footpath with the pump shaft of oil transfer pump, one end of asessory shaft 1 is provided with asessory shaft fastener hole 3, and the other end of asessory shaft 1 is connected with pump shaft end locking screw, and boosting-rod inserts and to screw the asessory shaft screw thread 2 that is threaded in the asessory shaft fastener hole 3.When installation or dismounting thrust bearing, to be connected with pump shaft end locking screw in the asessory shaft 1 screw-in thrust bearing, adopt boosting-rod to insert to screw in the asessory shaft fastener hole 3 the asessory shaft screw thread 2 that is threaded, after operation finishes, asessory shaft 1 is installed or disassembled.
The embodiment of the utility model oil transfer pump thrust bearing installing/dismounting device, it is to be made of with asessory shaft fastener hole 3 asessory shaft 1 and the screw thread 2 that is threaded, the asessory shaft 1 periphery setting screw thread 2 that is threaded, asessory shaft 1 is connected with the footpath with the pump shaft of oil transfer pump, one end of asessory shaft 1 is provided with asessory shaft fastener hole 3, the other end of asessory shaft 1 is connected with pump shaft end locking screw, and boosting-rod inserts and to screw the asessory shaft screw thread 2 that is threaded in the asessory shaft fastener hole 3.During use, the pump shaft screw thread 2 that is threaded is connected with pump shaft end locking screw, inserts to screw in the asessory shaft fastener hole 3 with boosting-rod and get final product.According to oil transfer pump pump shaft diameter and the different asessory shaft diameter of pump shaft end lock sleeve dimensioned, select the oil transfer pump thrust bearing assembly erecting device of the different diameters of axle can carry out the checking maintenance of oil transfer pump according to the oil transfer pump pump shaft in the use.
