Abstract
The utility model discloses a device for A28V130 plunger pump connection pad, a serial communication port, including oil blanket lid and connection pad, be equipped with the pilot hole of skeleton oil blanket, dismantle the dismantlement screw hole of screw hole and oil blanket lid on the oil blanket lid, be equipped with the pilot hole of oil blanket lid on the connection pad, the connection pad is connected with the oil blanket lid. The utility model discloses reduce the processing degree of difficulty of connection pad, simple structure assembly and disassembly is convenient. The two holes can be machined by only one process, so that the machining difficulty is reduced. Only need get during the assembly oil seal cover assembly with fix with screw can, need not dismantle whole connection pad from the pump body when changing the skeleton oil blanket, also need not disassemble use paint the screwed connection's that the screw thread is glued axle bush and dismantle parts such as input shaft bearing, only need follow use screw oil seal cover assembly ejecting can, avoided causing the damage of axle bush when changing the skeleton oil blanket simultaneously, the utility model provides the efficiency of assembly and maintenance.
Description
Technical Field
The utility model relates to a device for A28V130 plunger pump connection pad belongs to hydraulic pump spare part field.
Background
Due to the fact that the size of the connecting disc of the A28V130 plunger pump is large, after-sale maintenance and machining cost is increased, and leakage at the lip of the framework oil seal is inevitable in the service life period of the hydraulic plunger pump. Before the connection pad changes, need dismantle whole plunger pump when the skeleton oil blanket damages, disassemble so that change the skeleton oil blanket, but increased maintenance duration and the degree of difficulty like this and caused fluid extravagant simultaneously.
At present, a framework oil seal assembly hole and a bearing assembly hole are processed by two procedures. Through the analysis, the axiality of skeleton oil blanket pilot hole and bearing pilot hole need be guaranteed at certain within range, otherwise can cause the skeleton oil blanket to grind the life-span that reduces partially.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: how to solve must disassemble whole plunger pump when the skeleton oil blanket damages, skeleton oil blanket pilot hole and the bearing pilot hole on the connection pad divide into the problem of twice process processing.
In order to solve the technical problem, the technical scheme of the utility model a device for A28V130 plunger pump connection pad is provided, a serial communication port, including oil seal lid and connection pad, the screw hole is dismantled to the pilot hole that is equipped with the skeleton oil blanket on the oil seal lid, skeleton oil blanket and oil seal lid dismantles the screw hole, is equipped with pilot hole, oil seal lid fixed thread hole and the bearing pilot hole of oil seal lid on the connection pad.
Preferably, an O-shaped ring is arranged between the connecting disc and the oil sealing cover.
Preferably, the connecting disc is connected with the thread of the oil sealing cover.
Preferably, the framework oil seal is connected with the oil seal cover.
The utility model discloses it is convenient than original A28V130 plunger pump connection pad change skeleton oil blanket, is connected the oil blanket lid of the skeleton oil blanket of packing into with the connection pad. The utility model discloses reduce the processing degree of difficulty of connection pad, simple structure assembly and disassembly is convenient. Certain axiality need be guaranteed to bearing pilot hole and skeleton oil blanket pilot hole on the connection pad, and two labours of twice process processing need be divided into to original connection pad, only need one process can accomplish the processing in two holes after the change, have reduced the processing degree of difficulty. The connection pad passes through 8M 14's the screw connection with the pump body, is equipped with parts such as axle bush on the connection pad, input shaft, bearing, the assembly screw fixation for the oil seal cover assembly only need be drawn in the assembly of after-changing can, need not dismantle whole connection pad from the pump body when changing the skeleton oil blanket, also need not disassemble the use and paint the axle bush of the screw connection that the screw thread glued and dismantle parts such as input shaft bearing, only need follow use the screw to the oil seal cover assembly ejecting can, avoided causing the damage of axle bush when changing the skeleton oil blanket simultaneously, the utility model provides the high efficiency of assembly and maintenance.
