Description
Technical Field
The utility model relates to a chassis car structure field especially relates to a chassis car actuating mechanism.
Background
In the transmission process of the chassis vehicle, a motor is required to transmit power to a gear fixedly connected to a screw rod through a reduction gear to drive the screw rod to rotate, the screw rod drives a screw rod nut arranged on the screw rod to move axially along the screw rod, and the screw rod nut is fixedly connected to the chassis vehicle so as to drive the chassis vehicle to move. The traditional driving mode is as follows: the power supply line power supply converts alternating current into direct current through a frequency converter or a rectifying block, then the direct current is input into a direct current permanent magnet motor, power is transmitted to the screw rod through the reduction gear, and therefore the screw rod nut and the chassis vehicle are driven to move together.
This structure has the following disadvantages: 1) the motor needs special power transformation equipment to convert alternating current into direct current, so that the structural complexity is increased; 2) the motor and the reducer have high matching degree requirements, are often made into an integral part for use, increase the integral cost and are not easy to assemble and maintain.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a chassis car actuating mechanism optimizes motor, reduction gear and both assembly structure, solves above-mentioned problem.
In order to achieve the purpose, the utility model adopts the following technical proposal:
the utility model provides a chassis car actuating mechanism, it includes the dual-purpose motor of alternating current-direct current, reduction gear and end cover, a side and the dual-purpose motor of alternating current-direct current link firmly, the output shaft of the dual-purpose motor of alternating current-direct current stretches into in the end cover and is provided with the tooth's socket on the output shaft, be provided with reduction gear set in the reduction gear, reduction gear set includes input gear and output gear, the casing of reduction gear is arranged in to the input gear is external, the another side of end cover links firmly with the casing of reduction gear, and establish input gear cover wherein, the output shaft and the input gear meshing transmission of the dual-purpose motor.
Particularly, a first screw is arranged outwards from the inner wall of the end cover and is fixed with a shell of the alternating current and direct current dual-purpose motor.
Particularly, the end cover is connected with the shell of the speed reducer through a second screw.
To sum up, the beneficial effects of the utility model are that, compared with the prior art, chassis car actuating mechanism chooses for use the dual-purpose motor of alternating current-direct current and has cancelled alternating current and direct current conversion equipment, has simplified the structure, and is external with input, the output gear of reduction gear to form the components of a whole that can function independently structure, make things convenient for equipment integration and independent part maintenance, change between the part, practiced thrift the cost, the suitability is stronger.
Drawings
Fig. 1 is a schematic structural diagram of a chassis truck driving mechanism provided in an embodiment of the present invention.
Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Referring to fig. 1, the present embodiment provides a chassis driving mechanism, which includes an ac/dc motor 1, a speed reducer 2 and an end cover 3. One side of end cover 3 links firmly with alternating current-direct current motor 1, specifically be from the inner wall of end cover 3 outwards be provided with first screw 7, first screw 7 is fixed with alternating current-direct current motor 1's casing, alternating current-direct current motor 1's output shaft 4 stretches into in end cover 3 and is provided with the tooth's socket on the output shaft 4, be provided with reduction gear set in reduction gear 2, reduction gear set includes input gear 5 and output gear 6, input gear 5 externally arranges the casing of reduction gear 2, another side of end cover 3 links firmly with the casing of reduction gear 2, specifically adopt second screw 8 to connect between the two, and establish input gear 5 cover wherein, alternating current-direct current motor 1's output shaft 4 and input gear 5 meshing transmission. In addition, the meshing part of the output gear 6 is exposed out of the shell of the speed reducer 2 or can be directly externally arranged, so that the output gear is conveniently butted with an actuating mechanism.
In summary, the chassis vehicle driving mechanism adopts the AC/DC motor without the AC/DC conversion device, simplifies the structure, and externally arranges the input and output gears of the speed reducer, thereby forming a split structure, facilitating assembly integration and maintenance and replacement of independent parts among parts, saving the cost and having stronger applicability.
The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
