Abstract
A power-driven trundle comprises a wheel frame and an idler wheel. A motor and a transmission shaft are arranged on the wheel frame, a rotating shaft of the motor is connected with a worm, a worm wheel and a driving gear are arranged on the transmission shaft, the worm is matched with the worm wheel, an axle is fixed on the wheel frame, the idler wheel is installed on the axle, a driven gear is installed on the axle and is connected with the idler wheel, and the driven gear is meshed with the driving gear. The motor is started to enable the idler wheel to rotate through the worm wheel, the worm, the driving gear and the driven gear. The power-driven trundle is installed at the bottom end of a loading platform, and the movement of the loading platform can be achieved manually or in a remote control mode. The power-driven trundle is reasonable and compact in structure and wide in application range.
Description
Technical field
The utility model relates to a kind of castor that is arranged on the object lower end, specifically a kind of electronic castor.
Background technology
At present, can't rotate in the used time self of doing without external force for the castor that is arranged on the object lower end.After existing castor is arranged on the lower end of object, needs by external force traction or promote object, castor rotated, and then realize the movement of object.This situation of existing castor is restricted its range of use.
The utility model content
The purpose of this utility model is to provide a kind of electronic castor, and this castor self has power, and under manual control, the roller that it has can rotate.
For achieving the above object, the utility model adopts following scheme: electronic castor, have wheel carrier and roller, and motor and transmission shaft are housed on wheel carrier, the rotating shaft of motor connects with a worm screw, worm gear and driving gear are housed on transmission shaft, and worm and wheel coordinates, and is fixed with a wheel shaft on wheel carrier, roller is loaded on wheel shaft, one driven gear is housed on wheel shaft, and driven gear is connected with roller, driven gear and driving gear engagement.
By such scheme as seen, starter motor,, by worm gear, worm screw, driving gear, driven gear, can make roller rotate.This electronic castor is arranged on the bottom of load carrying platform, can realizes the movement of manual control or remote control load carrying platform.
The utility model is rational in infrastructure, compact, applied range.
Description of drawings
The structural representation of Fig. 1 the utility model one embodiment;
The A-A cutaway view of Fig. 2 Fig. 1.
The specific embodiment
Further illustrate the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1, Fig. 2
The electric foot wheel that the utility model provides has wheel carrier 1 and roller 7, motor 2 and transmission shaft 6 are housed on wheel carrier 1, the rotating shaft of motor 2 connects with a worm screw 3, worm gear 4 and driving gear 5 are housed on transmission shaft 6, worm gear 4 and driving gear 5 connect by key 17 with 6 of transmission shafts, and worm screw 3 coordinates with worm gear 4.Be fixed with a wheel shaft 10 on wheel carrier 1, roller 7 is loaded on wheel shaft 10, and a driven gear 8 is housed on wheel shaft 10, and driven gear 8 is connected with roller 7, driven gear 8 and driving gear 5 engagements.In the present embodiment, driven gear 8 and 7 is connected as a single entity, and also can make driven gear 8, roller 7 independent separately, and the connection structure by routine connects between the two.
For making the more compact structure of this electronic castor, in the present embodiment, wheel carrier 1 is the casing of up and down open at both ends, and motor 2, transmission shaft 6 and wheel shaft 10 all are in the inside of wheel carrier 1, and roller 7 exposes from the lower port of wheel carrier 1.
In the present embodiment, the mounting means of transmission shaft 6 on wheel carrier 1 is: a clutch shaft bearing 14 is equipped with respectively at the two ends of transmission shaft 6, two clutch shaft bearings 14 are loaded on respectively in the first through hole 1a that wheel carrier 1 both sides have, be connected with respectively a bearing carge 13 in the both sides of wheel carrier 1, bearing carge 13 covers clutch shaft bearing 14.
In addition, in the present embodiment, wheel shaft 10 is hollow shaft, the two ends of wheel shaft 10 are loaded on respectively in the second through hole 1b that wheel carrier 1 both sides have, the two ends of wheel shaft 10 back-up ring 12 that reclined respectively, passed bolt 11 in wheel shaft 10 and two back-up rings 12, and bolt 11 first line of a couplet are connected to nut 15.In addition, at driven gear 8 and 10, wheel shaft, the second bearing 9 is housed, at roller 7 and 10, wheel shaft, the 3rd bearing 16 is housed.
By Fig. 1, Fig. 2 as seen, starter motor 2, motor 2 drives worm screw 3 transmission worm gears 4, and worm gear 4 drives transmission shaft 6 and driving gear 5 rotates, then by driving gear 5 transfer driven gears 8, roller 7 is rotated.
