The second connection flange fastener hole that gripper shoe fastener hole in the vertical gripper shoe of frame matches, couples flange circular hole described second
It is externally provided with equally distributed the second motor fixing hole for fixing motor of least one set, it is therefore preferable to one group, described second motor
The Kong Xinyuan and second that the hole heart of fixing hole is constituted couples the concyclic heart of flange circular hole.Circular or annular protrusion design can facilitate handle
Couple flange and navigate in the vertical gripper shoe of motor L-type support, make motor-shaft extending and torque speed sensor axle stretch and be prone to centering,
Fast and easy is installed simultaneously, reduces motor and installs and change operator's skill set requirements.
The group number of described first motor fixing hole and the second motor fixing hole can be according to loading motor with by the kind of measured motor and type
Number and measure need 1 group, 2 groups or more than 3 groups are set.
The technological principle of the present invention: the two end axles of torque speed sensor is stretched in the connecting hole being inserted respectively into sensor Coupling Shaft also
Fixing connection, after each sensor Coupling Shaft assembles two bearings and is assemblied in the dead eye of U-shaped bearing block 13 by bearing holder (housing, cover)
In, two bearings in sensor Coupling Shaft can make sensor Coupling Shaft and moment of torsion rotating speed with the position of alignment sensor Coupling Shaft
The two end axles of sensor stretches centering, it is ensured that the two end axles of torque speed sensor is stretched and is not subject to moment of flexure.By measured motor and loading motor
Coupling flange and the fixing connection of L-type motor supporting base being fixed on T-slot flat board by motor respectively, motor-shaft extending is inserted into
In the connecting hole of motor Coupling Shaft and fixing connect, motor Coupling Shaft uses shaft coupling and sensor Coupling Shaft centering to connect.Work as electricity
The axle of machine is stretched the axle with torque speed sensor and is stretched when misaligning motor-shaft extending sensor Coupling Shaft is produced moment of flexure, and sensor is transferred
The opposing torque provided by the two bearings being assemblied in sensor Coupling Shaft is compensated without being delivered to moment of torsion by the moment of flexure on axle
The axle of speed probe is stretched, thus avoids torque speed sensor and bear moment of flexure, eliminates moment of flexure and on the impact of sensor and carries
High sensor accuracy class, can improve again the service life of sensor simultaneously.According to measurement requirement, need change different brands or
During the motor of different model, it is only necessary to select the motor being suitable for couple flange, without changing motor supporting base, simplify electricity
Installation process changed by machine, it is simple to operation, reduces human input, reduces use cost.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The technical staff of the industry should
This understanding, the present invention is not restricted to the described embodiments, and the simply explanation present invention's described in above-described embodiment and description is former
Reason, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, claimed
Scope is defined by appending claims, description and equivalent thereof.
