Abstract
The utility model discloses a positive-speed gearbox used for the driving electric motor of the escalator, in particular a positive-speed gearbox used for the driving electric motor driving two escalators. The positive-speed gearbox consists of a box body and an input shaft, two speed-changed shafts equipped in the box body. The input shaft is connected with the speed-changed shafts through a helical gear. The input shaft and the speed-changed shafts are positioned at the same sides of the box body. The utility model is structurally characterized in that the box body is equipped with two output shafts connected with the speed-changed shafts as well; two output shafts are rigidly connected in 1:1 transmission ratio through paired helical gears. And two output shafts are positioned at the same side of the box body. In addition, the input portion can use a worm wheel and worm wheel structure as well. The utility model has the advantages of a reasonable design structure, a low cost and the energy conversation.
Description
Technical field
The utility model relates to staircase driving host speed reducer, especially can drive the driving host speed reducer of two escalators simultaneously.
Background technique
The driving host of escalator all can only drive a staircase with speed reducer in the market, two bi-directional escalators of placing side by side will drive respectively by the driving host of two platform independent, every single ladder has one group of driving mechanism, so there is the shortcoming of complex structure, manufacture cost height, not enough energy saving in it.
Summary of the invention
Technical problem to be solved in the utility model provides reasonable in design, low, the energy-conservation staircase driving host speed reducer of cost.
The technical scheme in the invention for solving the above technical problem has: this speed reducer comprises casing and is installed in casing interior an input shaft, two variable-speed shafts, input shaft and variable-speed shaft are connected and are positioned at the same side of casing by helical gear, its structural feature is that two output shafts that link to each other with variable-speed shaft also are installed in casing, be that 1: 1 helical gear is rigidly connected by a pair of velocity ratio between two output shafts, and two output shafts are positioned at the same side of casing.
The technological scheme that the utility model adopted also has: this speed reducer comprises casing and is installed in casing interior a worm screw, a worm gear, wherein worm screw is as input shaft, its structural feature is that an output shaft that links to each other with worm-wheel shaft also is installed in casing, simultaneously worm-wheel shaft is also as output shaft, is that 1: 1 helical gear is rigidly connected and is positioned at the same side of casing by a pair of velocity ratio between described two output shafts.
The utility model compared with prior art, has following beneficial effect: compare with traditional two independent staircase driving host, increased an output shaft in the speed reducer casing, reduced a speed reducer and a motor simultaneously, whole cost declines to a great extent; Be that 1: 1 helical gear is rigidly connected by a pair of velocity ratio between these two output shafts, and two output shafts are positioned at the same side of casing, two output shafts rotate synchronously, and sense of rotation is opposite, speed is equal, can save a large amount of energy; The same staircase machine room upper that is arranged in traditional staircase of whole driving host only just can drive two two-way parallel elevators simultaneously by a driving host, has the advantage of structure.In addition, two kinds of technological schemes have been adopted in the input part of this speed reducer, a kind of be input shaft in conjunction with variable-speed shaft, a kind of is worm gear and worm screw, can be installed in different places according to actual conditions.

Embodiment
Embodiment 1:
Referring to Fig. 1, this speed reducer comprises casing 6, and an input shaft 1, first variable-speed shaft 2, second variable-speed shaft 3 are installed in casing 6, and input shaft 1 is connected by two pairs of helical gears with first, second variable-speed shaft 2,3; First output shaft 4 and second output shaft 5 also are installed in casing 6, wherein first output shaft 4 links to each other with second variable-speed shaft 3 by helical gear 7, be that 1: 1 helical gear 7 is rigidly connected by a pair of velocity ratio between second output shaft 5 and first output shaft 4, and the shaft extension of two output shafts 4,5 is positioned at the same side of casing 6.
During operation, motor drives input shaft 1 rotates, input shaft 1 drives first variable-speed shaft 2, second variable-speed shaft 3, first output shaft 4,5 rotations of second output shaft by many groups helical gear again, wherein first, second output shaft 4,5 rotates synchronously, but sense of rotation is opposite, speed equates, drives a staircase operation respectively, thereby realizes that a motor, double output shaft drive the effect of two-way conjoined staircase.
Embodiment 2:
Referring to Fig. 2, this speed reducer comprises casing 6, a worm screw 9, a worm gear 8 are installed in casing 6, wherein worm screw 9 is as input shaft, worm-wheel shaft 10 also is equipped with an output shaft 11 that links to each other with worm-wheel shaft 10 as first output shaft in casing 6, output shaft 11 is as second output shaft, be that 1: 1 helical gear 7 is rigidly connected by a pair of velocity ratio between worm-wheel shaft 10 and the output shaft 11, and the shaft extension of two output shafts is positioned at the same side of casing 6.
During operation, motor drives worm screw 9 is rotated, worm screw 9 drives worm gear 8, worm-wheel shaft 10 rotates, worm-wheel shaft 10 drives output shaft 11 by helical gear 7 again and rotates, wherein rotate synchronously as the worm-wheel shaft 10 of first output shaft with as the output shaft 11 of second output shaft, but sense of rotation is opposite, speed is equal, drives a staircase operation respectively, thereby realizes that a motor, double output shaft drive the effect of two-way conjoined staircase.
