To power so that torquemeter is easily damaged.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of hydraulic pump test clamping dresses
It puts, torquemeter is not easy to be damaged.
The purpose of this utility model adopts the following technical scheme that realization：
A kind of hydraulic pump tests clamping device, including motor, first shaft coupling, torquemeter and pump stent, the hydraulic pressure
Pump test clamping device further includes bearing, extension shaft and the bearing for being located on the extension shaft, the bearing and the bearing
Fixed, one end of the torquemeter is connected by the first shaft coupling with the motor, the other end of the torquemeter and institute
The one end for stating extension shaft is fixed, and the pump stent is used to fix with hydraulic pump.
Further, the other end of the torquemeter is fixed by one end of flat key and the extension shaft.
Further, the hydraulic pump test clamping device further includes pedestal and the line slideway arranged on the pedestal,
The pump stent forms prismatic pair with the pedestal by the line slideway.
Further, the torquemeter is secured by bolts in the bearing.
Further, the bearing is rolling bearing units, and the rolling bearing units are secured by bolts in the bearing.
Further, the hydraulic pump test clamping device further includes the ring flange that can be installed on hydraulic pump, described
Ring flange is fixed by bolt and the pump stent.
Further, the first shaft coupling is positive coupling.
Further, hydraulic pump test clamping device further includes second shaft coupling, the other end of the extension shaft with
The second shaft coupling connection.
Further, the second shaft coupling is yielding coupling.
Compared with prior art, the beneficial effects of the utility model are：
Hydraulic pump provided by the utility model tests clamping device, including motor, first shaft coupling, torquemeter, lengthening
Axis, bearing, bearing and pump stent, for the pump stent for being fixed with hydraulic pump, one end of the torquemeter passes through first shaft coupling
