Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
The specific implementation mode of the present invention is further described below in conjunction with the accompanying drawings.
In Fig. 1, including motor housing 1, gear-box 2, keypad 3, motor 4, friction plate 5, plain thrust bearing 6, torsional spring
7, brake gear 8, drive shaft 9, lead screw 10, feed screw nut 11, outer tube 12, inner tube 13, bolt 14,15, first watts of footing bearing
Lid 16, second FE Tiler 17 etc..
As shown in Figure 1, the present invention is a kind of motor-driven jack, including gear-box 2 and the electricity for driving gear-box 2 to operate
Machine 4, the output end of gear-box 2 are arranged drive shaft 9,9 lower end connection wire rod 10 of drive shaft, and feed screw nut is threadedly coupled on lead screw 10
11,11 external peripheral surface of feed screw nut fixes inner tube 13, and 13 outside of inner tube is arranged outer tube 12, and 12 upper end of the outer tube is fixed on
2 bottom of gear-box, 13 lower end of inner tube connect footing bearing 15 by bolt 14；Brake gear 8 is set in the drive shaft 9.
Brake gear 8 includes friction plate 5, single thrust bearing 6, torsional spring 7, the first FE Tiler 16, the second FE Tiler 17, wherein rubbing
Pad 5 is set to 9 upper position of drive shaft, and 5 lower section of friction plate sets gradually 6, first watts of the second FE Tiler 17, single thrust bearing
Lid 16, first FE Tiler 16 are fixedly connected with drive shaft 9, and torsional spring 7 is set to the first FE Tiler 16,17 outer surface of the second FE Tiler.
The tube surfaces of footing bearing 15 uniformly open up several through-holes from down to up, and 13 lower end of inner tube opens up radial through-hole,
The radial through-hole is connected with any through-hole of bearing tube surfaces by bolt 14.
Lead screw 10 is ball screw
Motor housing 1 is arranged in 4 top of motor, and the keypad 3 for controlling 4 operating mode of motor is arranged in 1 side of motor housing.This
Automatic lifting memory function may be implemented by PCB circuit board in PCB circuit board built in keypad 3 in invention product.
The course of work of the present invention is as follows：Motor 4 is converted to high-speed electric expreess locomotive 4 by PCB circuit controls, by gear-box 2
