Tool, technology and carrying capacity are undoubtedly the trip for greatly facilitating people.
The main transmission of traditional escalator connects retarder simultaneously using the form of host connection retarder by host
It is moved by chain-driving main shaft.During this traditional chain drive, the abrasion due to chain or passenger's load mistake
Fracture that is big and leading to chain, the generations of many staircase accidents precisely due to main transmission chain break cause staircase downlink or
Downlink is switched to by uplink suddenly, terraced road step operation under gravity can accelerate downlink suddenly from normal speed.Work as passenger
When boarding due under unexpected acceleration guild make passenger's crank and generate and drop injury, touched during falling down
Personnel death can also be caused by bumping against step or ground serious situation, especially when hoisting depth is relatively high, passenger
Compare it is more, be expressed to from above below and generate more serious accident.
Utility model content
The purpose of this utility model is that proposing a kind of relatively reliable effective escalator transmission system of transmission.
For this purpose, the utility model uses following technical scheme：
A kind of escalator transmission system, including step and the motor for driving the step, the motor and deceleration
Device is connected.The retarder is three-stage gear speed reducer, has first gear, second gear and third gear, described electronic
Machine is connected with first gear, and the first gear engages with the second gear and the second gear is driven to rotate, described
Second gear engages with the third gear and the third gear is driven to rotate, and the third gear passes through spline and main transmission
Axis is connected, and to drive stepping motion, realizes the transportation function of escalator.
Further, the motor is directly connected to the first gear or is connect by shaft coupling, in order to protect electricity
Motivation axis, it is preferred to use the mode of shaft coupling connection.
Further, the third gear engages with the 4th gear and the 4th gear is driven to rotate.
Further, the 4th gear engages with the 5th gear and the 5th gear is driven to rotate.
Further, the 5th gear is connect by axis with gyroscope wheel.
Further, the axis is fixed on supporting rack and the bearing by being arranged on support frame as described above rotates.
Further, the bearing is rolling bearing, can realize that other bearings that the present invention is driven are also possible.
Further, the gyroscope wheel is coaxial with the 5th gear and drives handrail to move using frictional fit,
It is achieved in the movement of handrail system.
In the present invention, escalator transmission system substitutes traditional chain drive using gear drive, avoids
Abrasion or passenger load of the escalator due to chain are excessive and lead to the fracture of chain, cause that asking for staircase accident occurs
Topic, and use gear drive so that the operation of escalator is more steady, power transmission it is relatively reliable effectively, safety into
One step is promoted.

Specific implementation mode
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
The utility model provides a kind of escalator transmission system.As shown in Figure 1, the escalator transmission system uses tooth
Wheel transmission includes the motor 1 of step and driving step.In the present embodiment, motor 1 is connected directly with retarder, this subtracts
Fast device is three-stage gear speed reducer, with first gear 2, second gear 3 and third gear 4.Motor 1 and first gear 2
It is connected, for example, motor 1 can be directly connected to first gear 2 or be connect by shaft coupling, in order to protect motor
Axis improves the service life of motor, it is preferred to use in such a way that shaft coupling is connected.First gear 2 is nibbled with second gear 3
It closes, the power of motor is thus transmitted to second gear 3 by first gear 2 and second gear 3 is driven to rotate, second gear
3 engage with third gear 4, thus and third gear 4 are driven to rotate.In addition, as shown in Fig. 2, third gear 4 passes through spline and master
Transmission shaft 5 is connected, and the power of motor 1 is thus transmitted to main biography by first gear 2, second gear 3 and third gear 4
Moving axis 5 realizes the transportation function of escalator to drive stepping motion.
As depicted in figs. 1 and 2, third gear 4 is engaged with the 4th gear 6, and the power of motor is thus passed through the first tooth
Wheel 2, second gear 3 and third gear 4 are transmitted to the 4th gear 6 and drive the rotation of the 4th gear 6, and the 4th gear 6 and the
Five gears 7 engage, thus by the power of motor by first gear 2, second gear 3, third gear 4 and the 4th gear 6 simultaneously
The 5th gear 7 is driven to rotate.5th gear 7 is fixed on supporting rack 9 by axis connection coaxial with gyroscope wheel 8, axis and by setting
The bearing 10 set on supporting rack 9 rotates.Bearing 10 can be rolling bearing, optionally, can realize its being driven of the invention
Its bearing is also possible.Since gyroscope wheel 8 and the 5th gear 7 are coaxial, the 5th gear 7 is rotated synchronously with gyroscope wheel 8, this
When be held on the periphery of gyroscope wheel 8 and moved under the action of frictional force with the handrail of 8 frictional fit of gyroscope wheel, to real
The operation of existing handrail system.
In the present invention, in the operational process of escalator, pass through a series of tooth between step and motor 1
Wheel transmission passing power avoids in chain drive since chain wear or passenger's load are excessive and chain breakage is caused to be made
The case where at accident.Further, since dynamical system uses gear drive so that the operation of escalator is more steady, and power passes
Dynamic relatively reliable effective, safety is further promoted.
Note that the technical principle that above are only the preferred embodiment of the utility model and used.Those skilled in the art
It will be appreciated that the utility model is not limited to specific embodiment described here, can carry out for a person skilled in the art various
Significantly change, readjust and substitutes without departing from the scope of protection of the utility model.Therefore, although by implementing above
Example is described in further detail the utility model, but the utility model is not limited only to above example, is not taking off
Can also include other more equivalent embodiments in the case of conceiving from the utility model, and the scope of the utility model is by institute
Attached right determines.
