Summary of the invention
The purpose of this utility model be to provide a kind of small-sized, do not need to dismantle the locked rotor torque pick-up unit that running torque test board can detect it.
The purpose of this utility model is achieved through the following technical solutions:
A locked rotor torque pick-up unit for running torque test board, is fixed on running torque test board, is made up of locked rotor torque drive unit and moment sensor two parts integral type; Locked rotor torque drive unit comprises driving handwheel, static drive wheel box, driving shaft and input torque driving head; Moment sensor comprises torque sensor; With output torque driving head;
Described driving handwheel and static drive wheel box respectively have two, and two driving handwheels are fixed on the central shaft outside two static drive wheel boxes symmetrically; Two static drive wheel boxes are relative; Driving shaft is connected to inside two static drive wheel boxes, and lower end is connected with input torque driving head, drives input torque driving head to rotate; Torque sensor is arranged on below input torque driving head; Output torque driving head is located at bottom torque sensor, corresponding with the torque sensor in running torque test board.
Torque sensor is provided with torque sensor external cable interface, connects with the standard torque signals cable of outside.
The mounting casing be arranged on running torque test board is equipped with outside described locked rotor torque drive unit and moment sensor.
Locked rotor torque drive unit and moment sensor are fixed on mounting casing respectively by drive unit mounting screw and sensing device mounting screw.
The beneficial effects of the utility model:
1, device is small-sized, portable, is the locked rotor torque pick-up unit of a set of independently standard.
2, device is especially used as the standard detectors of running torque test board, and testing process does not need to disintegrate to running torque test board, has evaded the disintegration risk of running torque test board.
What 3, adopt this device to carry out running torque test board is Whole verification, detects and more improves and science.
4, this device is that the user of running torque test board provides a kind of in production scene to the device that running torque test board detects, testing can being made to become quick, simple, economic, instead of regular trust and send testing outside.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the overall schematic that the utility model is arranged on running torque test board.
Be labeled as in figure:
Output torque driving head 1, sensing device mounting screw 2, mounting casing 3, torque sensor 4, input torque driving head 5, drive unit mounting screw 6, fastening nut 7, driving handwheel 8, static drive wheel box 9, driving shaft 10, torque sensor external cable interface 11, running torque test board 12.
Embodiment
See Fig. 1 and Fig. 2, the locked rotor torque pick-up unit of running torque test board, is fixed on running torque test board 12, is made up of locked rotor torque drive unit and moment sensor two parts integral type.Locked rotor torque drive unit comprises driving handwheel 8, static drive wheel box 9, driving shaft 10 and input torque driving head 5.Moment sensor comprises torque sensor 4 and output torque driving head 1.
Described driving handwheel 8 and static drive wheel box 9 respectively have two, and two driving handwheels 8 are fixed on the central shaft outside two static drive wheel boxes 9 symmetrically by fastening nut 7.Two static drive wheel boxes 9 are relative, and driving shaft 10 is connected to inside two static drive wheel boxes 9, and lower end is connected with input torque driving head 5, drive input torque driving head 5 to rotate.Torque sensor 4 is arranged on below input torque driving head 5, output torque driving head 1 is located at bottom torque sensor 4, corresponding with the torque sensor in running torque test board 12, the torque signal of two torque sensors is delivered to detection system, and (this detection system is existing equipment, do not belong to invention category of the present utility model, this instructions repeats no more).Torque sensor 4 is provided with torque sensor external cable interface 11, connects with the standard torque signals cable of outside.The mounting casing 3 be arranged on running torque test board 12 is equipped with outside described locked rotor torque drive unit and moment sensor.Locked rotor torque drive unit and moment sensor are fixed on mounting casing 3 respectively by drive unit mounting screw 6 and sensing device mounting screw 2.
Locked rotor torque described in the utility model detects, refer under the standard torque sensor of this pick-up unit and all static non rotating state of torque sensor of tested running torque test board 12, quiet moment of torsion is applied to torque sensor 4 by driving handwheel 8, locked rotor torque drive unit, this moment of torsion is also synchronously delivered to the torque sensor of running torque test board 12, the value of two torque sensors detected by detection system and simultaneous display in the display device.According to national metrological verification regulations, carry out ladder stepping load mode, corresponding to each load(ing) point, two sensors carry out point-to-point detection comparison, by check analysis, judge the moment inspecting accuracy value of tested running torque test board.During work, the checking table driving head in this device and running torque test board are carried out clamping and fix with flange.
