Description
Technical field
The utility model relates to the drive technology field, and what relate to especially is a kind of transmission shaft drive unit.
Background technique
As everyone knows, drive unit will offer on the take-off (propeller) shaft from the energy and the speed of motor, thereby make take-off (propeller) shaft working properly, but the gear engagement on the output shaft of gear in the speed reduction gearing and 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.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of transmission shaft drive unit is provided.
For achieving the above object, technical solution of the present utility model is: a kind of transmission shaft drive unit, comprise lid, be installed on the interior transmission device of lid and the described transmission device of drive motor of drive transmission and comprise the first duplex drive wheel, second duplicate gear and the 3rd gear, described lid comprises loam cake and 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 drive motor runs through base, and be fixedly connected on the base by screw, described driving mechanism and drive motor are fixed with a drive wheel that is connected with leather strap by the leather strap interlock on the output shaft of drive motor.
The drive wheel of the described 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, small gear in second duplicate gear and three gear engagement.
Described the 3rd gear is fixed on the output rotation axis, and an end of described output rotation axis is sheathed on the axle sleeve of base for the output rotation axis rotation, and the other end runs through loam cake and is connected with fastening.
Described drive motor is a slow-speed of revolution d.c. motor.
By adopting above-mentioned technological scheme, the beneficial effects of the utility model are: the utility model is given take-off (propeller) shaft by utilizing leather strap with drive motor energy and speed transmission, can reduce noise, can reduce wear, can reach the deceleration purpose, reduce cost by leather strap, this device has advantages such as simple in structure, easy processing and fabricating, practical, applied range.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Further specify the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of transmission shaft drive unit of the present utility model, comprise lid 1, be installed on the transmission device 2 in the lid 1 and the drive motor 3 of drive transmission 2, described transmission device 2 comprises the first duplex drive wheel 21, second duplicate gear 22 and the 3rd gear 23, described lid 1 comprises loam cake 11 and base 12, loam cake 11 is provided with the wheel shaft 111 that rotates for the first duplex drive wheel 21, base 12 is provided with the wheel shaft 121 that rotates for second duplicate gear 22, the output shaft 31 of drive motor 3 runs through base 12, and be fixedly connected on the base 12 by screw, described driving mechanism 2 passes through leather strap 4 interlocks with drive motor 3, be fixed with a drive wheel 32 that is connected with leather strap 4 on the output shaft 31 of drive motor 3, the drive wheel 32 of the described 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, small gear in second duplicate gear 22 the and 23 engagements of three gears, described the 3rd gear 23 is fixed on the output rotation axis 5, one end of described output rotation axis 5 is sheathed on the axle sleeve 122 of base 12 for output rotation axis 5 rotations, the other end runs through loam cake 11 and is connected with fastening, described drive motor 3 is slow-speed of revolution d.c. motor, and 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.
Above-described, only be a preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
