Abstract
The utility model relates to a frock is dismantled to non - drive end bearing of double bracing pump, it is including location backplate, an even number locking screw, an even number nut, company's axial filament thick stick, an axle head nut, the location backplate is passed to an even number locking screw symmetry, and locking screw rod one end is connected with the drive end bearing housing of double bracing pump, and the locking screw rod other end passes through the nut with the location backplate to be connected, waits that the pump shaft end -to -end connection of dismantling the double bracing pump links the axial filament thick stick, links the axial filament thick stick and passes the location backplate, links the axial filament thick stick and fix a position the backplate to pass through the axle head nut and be connected. The beneficial effect of the utility model: simple structure, simple to operate can prevent that the double bracing pump from overhauing rotor shaft that the in -process caused owing to the structure reason of double bracing pump own and to the drunkenness, effectively preventing rotor axial displacement, and cause the machine to seal and damage.
Description
Technical field
The utility model relates to flight-line maintenance field, is specifically related to a kind of dual-gripper pump non-driven-end bearing disassembling fixture.
Background technology
Dual-gripper pump anti-drive end is two bicker contact ball bearings (location bearing), because bearing is tighter in dismounting bearing housing process, rotor easily produces axial displacement, prior art be install on machine sealed cover suitable thickness location locking plate and lock, machine is sealed axle sleeve and pump shaft jackscrew unclamps, the axial force produced during dismounting is far longer than the power of mechanical seal stay, because machine envelope axle sleeve inner O type circle still has certain tightness with pump shaft, mechanical seal sleeve still has the possibility of play together with pump shaft, mechanical seal sleeve play causes machine envelope dynamic and static ring decrement to change, cause mechanical seal leakage.
Summary of the invention
In view of the defect that prior art exists, the utility model provides a kind of dual-gripper pump non-driven-end bearing disassembling fixture, can prevent in dual-gripper pump maintenance process, due to the reasons in structure of dual-gripper pump own, and the rotor axial play caused.
For achieving the above object, the technical scheme that the utility model adopts is a kind of dual-gripper pump non-driven-end bearing disassembling fixture, and it comprises location backboard, even number tie down screw, even number nut, connecting shaft leading screw, a shaft end nut; Even number tie down screw is symmetry through location backboard, lock nut one end is connected with the drive end bearing casing of dual-gripper pump, the lock nut other end is connected by nut with location backboard, the pump shaft end of dual-gripper pump to be removed connects connecting shaft leading screw, connecting shaft leading screw is through location backboard, and connecting shaft leading screw is connected by shaft end nut with location backboard.Described tie down screw is two.
The beneficial effects of the utility model: structure is simple, easy for installation, can to prevent from dual-gripper pump maintenance process, due to the rotor axial play that the reasons in structure of dual-gripper pump own causes, effectively preventing rotor axial displacement, and cause machine to seal to damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, location backboard, 2, tie down screw, 3, nut, 4, pump shaft, 5, bearing housing, 6, shaft end nut, 7, connecting shaft leading screw.
Detailed description of the invention
A kind of dual-gripper pump non-driven-end bearing disassembling fixture, it comprises location backboard 1, two tie down screws 2, two nuts 3, connecting shaft leading screw 7, shaft end nut 6; Even number tie down screw 2 is symmetry through location backboard 1, lock nut 2 one end is connected with the bearing housing 5 of dual-gripper pump to be removed, lock nut 2 other end is connected by nut 3 with location backboard 1, pump shaft 4 end of dual-gripper pump to be removed connects connecting shaft leading screw 7, connecting shaft leading screw 7 is through location backboard 1, and connecting shaft leading screw 7 is connected by shaft end nut 6 with location backboard 1.
Structure of the present utility model is simple, easy for installation, can to prevent from dual-gripper pump maintenance process, due to the rotor axial play that the reasons in structure of dual-gripper pump own causes, effectively preventing rotor axial displacement, and causes machine to seal to damage.
