Abstract

The invention relates to a gear-driven device which is a resultant-force device taking a plurality of small motors as power sources. The gear-driven device comprises a motor, driving gears and a driven gear; the motor and the driving gears are matched closely and provide power for the gear-driven device; two or more driving gears are arranged at the periphery of the driven gear and meshed with the driven gear respectively; the driving gears rotate synchronously and concertedly, so that the driven gear rotates, and the driving gears act on the driven gear jointly so as to drive the driven gear; and the driven gear is used to transfer force to the outside of the gear-driven device. The gear-driven device is a good power-driven device and can be used for the equipment needing to be provided with power.

Description

A kind of gear device

Technical field

The invention belongs to the dynamic power machine field, be specifically related to a kind of new gear drive unit.

Background technology

Work more and morely in complex environment along with being engaged in, the requirement of the special equipment that need to work in complex environment is also more and more higher.Owing to be operated in the complex environment, the power set that some special equipment needs no longer are traditional, so power set are in complex environment and become very important.The present invention is under such background and produce so.The fields such as the picture fire-fighting is explosive, nuclear power industry, the exploration disaster relief, the special equipment that is applied in these fields requires stricter to power.Power set on the common meaning are applied in these fields might cause inconceivable consequence, increases such as the dangerous factor in the fire-fighting, and the accident potential in the disaster relief improves.The present invention is exactly the deficiency of using in these fields in order to overcome existing power set, and a kind of power solution that proposes.

Summary of the invention

The purpose of this invention is to provide a kind of Power Drive Unit, can be the equipment that power need to be provided and use.

The gear device that the present invention proposes is comprised of motor, driving gear and driven gear; Motor and driving gear close-fitting also provide power for it, two or more driving gears are arranged in the driven gear periphery, mesh with driven gear respectively, the driving gear synchronous coordination rotates so that driven gear externally provides power, and the combination between the motor of varying number, driving gear and the driven gear can form a gear device.

The gear device of another kind of form is comprised of motor, driving gear and driven gear.The direct close-fitting of described motor and driving gear and for it provides power, two or more driving gears mesh successively and finally mesh with driven gear, and all driving gears rotate synchronously, jointly drive driven gear.

The gear diameter of using in this gear device is selected according to actual needs, is convenient to like this use in the environment of reality this drive unit.The quantity of the motor in each gear device can by n (n=2,3,4 ...) individual composition, n is larger, and corresponding driving load capacity is stronger; The number n of motor and driving gear (n=2,3,4 ...) can not use correspondingly;

Driving gear is connected engagement system to connect with driven gear, the gear size is unrestricted.When adopting a plurality of gear devices as a drive unit, the output of all driven gears is finally made a concerted effort in a place.

Driving gear and driven gear link together by engagement system.The function of this driven gear is: compile the power of all driving gears, be passed to the outside.

The outputting power mode of described driven gear can be the way of output of location hole, also can be the outstanding location division of driven gear is exported as power.

The gear device drive principle: during the driving gear co-ordination, because driving gear links to each other by engagement system with driven gear, driving gear will drive the driven gear rotation so.When the dynamic load of driven gear band, at this moment all driving gears will rotate thereby drive driving gear with joint efforts in driven gear, and then drive load.

The present invention has following advantage:

The present invention can make a concerted effort the power of a plurality of motors in an output device by gear, is used for driving load or again makes a concerted effort, and can obtain larger actuating force like this, is convenient to adapting to special operational environment.With gear carry out with joint efforts than other mode tools of making a concerted effort be rigidly connected, power transmission is direct, time lag is little, the efficient advantages of higher.And, adopt this structure, can also adjust easily as required actuating force, when demand motive power is large, increase the working quantity of driving gear and motor, and the actuating force that needs hour, can reduce the working quantity of driving gear and motor.Form than a driven gear of a driving gear driving has more practicality.

Specific implementation method

Referring to Fig. 1, gear device of the present invention is comprised of with driven gear 1 motor 3, driving gear 2, needing to be suitable for the equipment of power to use.Motor 3 and driving gear 2 close-fittings and for it provides power have 8 groups, i.e. n=8, and eight driving gears 2 are around being arranged in driven gear 1 periphery, and with driven gear 1 engagement, all driving gear 2 synchronous coordinations rotate so that driven gear 1 externally provides power respectively.Whole device is done support by a fixed disk 6.

Referring to Fig. 2, the motor 3 of this gear device and the group number of driving gear 2 are two groups, i.e. n=2.

Referring to Fig. 3, the motor 3 of this gear device and the group number of driving gear 2 are three groups, i.e. n=3.

More than the sort of form be more suitable for equipment and can determine according to actual needs.For requiring the large equipment of actuating force, can select the larger gear device of n, for requiring the less equipment of actuating force can select the less gear device of n.

Referring to Fig. 4, this gear device is comprised of with driven gear 1 motor 3, driving gear 2, the group number of motor 3 and driving gear 2 is 8 groups, be n=8, difference is, 8 groups of motors 3 and driving gear 2 mesh successively, finally mesh driven gear 1, and driving gear 2 synchronous coordinations rotate so that driven gear 1 externally provides power.

Fig. 5 and Fig. 6 are respectively the use state diagrams of two groups and three groups of motors 3 and driving gear 2.

Referring to Fig. 7, the series connection of three gear devices shown in Figure 1, output shaft 5 passes successively the power of 4, three gear devices of center positioning hole of the driving gear of three devices and makes a concerted effort on output shaft 5 outputting power.

Referring to Fig. 8, the parallel form of three gear devices shown in Figure 4, output shaft 5 pass successively the power of 4, three gear devices of center positioning hole of the driving gear of three devices and make a concerted effort on output shaft 5 outputting power.
