Description

A kind of transmission device

Technical field:

The utility model relates to the drive technology field, refers in particular to a kind of transmission device.

Background technique:

Well-known from every side, utilize transmission device to offer on the take-off (propeller) shaft, thereby make take-off (propeller) shaft working properly from the energy and the speed of motor.Existing transmission device, gear engagement on the gear in the speed reduction gearing and the output shaft of drive motor, though speed reduction gearing can reach decelerating effect, but can produce certain noise when gear on the output shaft of drive motor and the gear engagement in the speed reduction gearing, and wearing and tearing easily between the gear, even cause gear to be scrapped, thereby can't satisfy the demands of consumers.

In sum, there is the improved place of some needs in transmission device at present, and the applicant also is in this purpose just and creates design the utility model.

The model utility content:

Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, the transmission device that provide a kind of processing and fabricating simple in structure, easy, practical, applied range, can reduce noise, can reduce wear, can reach the deceleration purpose, reduce cost.

For solving the problems of the technologies described above, the utility model has adopted following technological scheme: this transmission device comprises: the drive motor of carrier, driving mechanism and drive transmission device, described driving mechanism and drive motor are by a leather strap interlock.

Be fixed with a drive wheel for the leather strap connection on the output shaft of described drive motor.

Described driving mechanism comprises: the first duplex drive wheel, second duplicate gear and the 3rd gear, wherein the large drive wheel of the first duplex drive wheel is by the drive wheel interlock on the output shaft of leather strap and drive motor, pinion in the gearwheel in second duplicate gear and the first duplex drive wheel, the pinion in the 3rd gear and second duplicate gear.

Described carrier comprises: loam cake, base, on cover and be provided with the wheel shaft that rotates for the first duplex drive wheel, base is provided with the wheel shaft that rotates for second duplicate gear.

The output shaft of described drive motor runs through base and is fixedly connected on the base.

Described the 3rd gear is fixed on the output rotation axis, and an end of output rotation axis is sheathed on base on the axle sleeve of output rotation axis, and the other end runs through loam cake and is connected with fastening.

In summary, the utility model utilizes a leather strap to give take-off (propeller) shaft with drive motor energy and speed transmission, can reduce noise, can reduce wear, can reach the deceleration purpose, reduce cost by leather strap.In addition, this transmission device has advantages such as simple in structure, easy processing and fabricating, practical, applied range.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of loam cake in the utility model;

Fig. 3 is the part assembling schematic representation of Fig. 1;

Fig. 4 is that Fig. 3 assembles schematic representation.

Embodiment:

Shown in Fig. 1～4, this practicality newly comprises: the drive motor 3 of carrier 1, driving mechanism 2 and drive transmission device 2.

Particularly:

Above-mentioned carrier 1 comprises: loam cake 11, base 12, loam cake 11 are provided with the wheel shaft that rotates for the first duplex drive wheel 21, and base 12 is provided with the wheel shaft that rotates for second duplicate gear 22.Loam cake 11 is connected to form carrier 1 with base 12 by screw.Driving mechanism 2 is installed in the carrier 1.Driving mechanism 2 drives by drive motor 3.The output shaft 31 of drive motor 3 runs through base 12 and is fixedly connected on the base 12 by screw.Driving mechanism 2 passes through a leather strap 4 interlocks with drive motor 3, can reduce noise, can reduce wear, can reach the deceleration purpose, can reduce cost by leather strap 4.Allow leather strap 4 be connected for convenience, on the output shaft 31 of drive motor 3, be fixed with a drive wheel 32 for leather strap 4 connections with drive motor 3.

Above-mentioned driving mechanism 2 comprises: the first duplex drive wheel 21, second duplicate gear 22 and the 3rd gear 23, wherein the large drive wheel 32 of the first duplex drive wheel 21 is by drive wheel 32 interlocks on the output shaft 31 of leather strap 4 and drive motor 3, pinion in the gearwheel in second duplicate gear 22 and the first duplex drive wheel 21, the pinion in the 3rd gear 23 and second duplicate gear 22.The 3rd gear 23 is fixed on the output rotation axis 5, and an end of output rotation axis 5 is sheathed on the axle sleeve of base 12 for output rotation axis 5 rotations, and the other end runs through loam cake 11 and is connected with fastening.

Above-mentioned drive motor 3 is slow-speed of revolution d.c. motor, and this drive motor 3 can be under zero load, and when per minute 700-800 changeed, electric current was below 10MA, under the 8g-cm load; When per minute about 500 changeed, electric current was below 20MA.These drive motor 3 output powers are bigger than general similar d.c. motor under slow-speed of revolution situation.This drive motor 3 can reduce friction between motor internal commutator and the brush by the slow-speed of revolution, increases the life-span.
