Summary of the invention
The purpose of this utility model provide a kind of can rapid adjustment load, the adjustment of load scope is large and transmission efficiency is high food refuse disposer motor torque Weight detector.
For achieving the above object, the utility model food refuse disposer motor torque Weight detector, comprise stroboscope and moment load device, the moment load device is comprised of frame, hold down gag and frictional disk, hold down gag is installed in the upper rack centre position, frictional disk is connected with frame by tested machine shaft, vertically is fixed with the screw corresponding with stroboscope on frictional disk.
Described frame is by pillar, location-plate, base, straight pin, stage clip and web joint form, on four angles of base, vertically be fixed with four pillars, the location-plate that can place motor is installed at the middle part of four pillars, four pillars above location-plate are respectively arranged with straight pin, the top of four pillars connects into an integral body by web joint, be provided with screw in the web joint centre position, this screw is connected with screw flight on the hold down gag, four pillars between the pressing plate on the hold down gag and straight pin are respectively arranged with stage clip, at location-plate limited block are installed.
Described hold down gag is comprised of screw rod, pressing plate, fixed block, friction disc, handle and pressure transducer, the screw rod upper end that has been threaded with web joint is fixed with handle, the screw rod lower end is connected with the pressing plate upper surface by pressure transducer, being provided with four jiaos of pressing plates can be in the hole that pillar slides, the pressing plate lower surface is connected with friction disc by fixed block, pressure transducer by be arranged on web joint on tensimeter be connected.
The center line of described hold down gag with coexisted on the axis by the center line of measured motor.
After adopting this structure, because the moment load device is comprised of frame, hold down gag and frictional disk, hold down gag is installed in the upper rack centre position, and frictional disk is connected with frame by tested machine shaft, vertically is fixed with the screw corresponding with stroboscope on frictional disk.Thereby have can rapid adjustment load, the adjustment of load scope is large and the transmission efficiency advantages of higher.
Description of drawingsThe utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is that the master of the utility model food refuse disposer motor torque Weight detector looks schematic diagram.
