Description

a gear drive

technical field

The invention belongs to the field of power machinery, and in particular relates to a novel gear drive device.

Background technique

As more and more people are engaged in work in complex environments, the requirements for special equipment that need to work in complex environments are also getting higher and higher. Due to working in a complex environment, the power unit required by some special equipment is no longer in the traditional sense, so the power unit becomes very important in a complex environment. So the present invention is produced under such background. In fields such as fire protection and explosives removal, nuclear energy industry, expedition and disaster relief, the special equipment used in these fields has strict power requirements. The application of power devices in the ordinary sense in these fields may cause unimaginable consequences, such as the increase of unsafe factors in fire protection and the increase of accident hazards in disaster relief. The present invention proposes a power solution in order to overcome the deficiencies in the application of existing power devices in these fields.

Contents of the invention

The object of the present invention is to provide a power drive device that can be used for equipment that needs to provide power.

The gear driving device proposed by the present invention is composed of a motor, a driving gear and a driven gear; the motor and the driving gear are tightly matched and provide power for it, and two or more driving gears are arranged on the outer periphery of the driven gear and mesh with the driven gear respectively. The synchronous and coordinated rotation of the driving gear enables the driven gear to provide power to the outside, and the combination of different numbers of motors, driving gears and driven gears can form a gear drive device.

Another form of gear drive consists of a motor, a driving gear and a driven gear. The motor is directly matched with the driving gear and provides power for it. Two or more driving gears mesh in sequence and finally mesh with the driven gear. All the driving gears rotate synchronously to jointly drive the driven gear.

The diameter of the gears used in the gear drive device is selected according to actual needs, so that the drive device can be used in an actual environment. The number of motors in each gear drive can be composed of n (n = 2,3,4,...), the larger n is, the stronger the corresponding drive load capacity is; the number of motors and driving gears n (n = 2 ,3,4,…) can not be used in one-to-one correspondence;

The driving gear and the driven gear are connected by meshing, and the size of the gear is not limited. When multiple gear drive devices are used as a drive device, the output of all driven gears should be finally combined in one place.

The driving gear and the driven gear are connected together by meshing. The function of the passive gear is to gather the forces of all the driving gears and transmit them to the outside.

The power output mode of the driven gear may be the output mode of the positioning hole, or the protruding positioning part of the driven gear may be used as the power output.

The driving principle of the gear drive device: when the driving gear works in coordination, since the driving gear and the driven gear are connected by meshing, the driving gear will drive the driven gear to rotate. When the driven gear drives the load, all the driving gears will work together on the driven gear to drive the driving gear to rotate and then drive the load.

The present invention has the following advantages:

The present invention can combine the power of multiple motors to one output device through gears to drive loads or re-combine the forces, so as to obtain greater driving force and facilitate adaptation to special working environments. Compared with other methods of combining forces, the use of gears for combining forces has the advantages of rigid connection, direct force transmission, small time lag, and high efficiency. Moreover, with this structure, the driving force can be adjusted conveniently as required. When the driving force is large, the number of driving gears and motors can be increased, and when the driving force is small, the number of driving gears and motors can be reduced. Compared with the form in which a driving gear drives a passive gear, it is more practical.

Specific implementation method

Referring to Fig. 1, the gear driving device of the present invention is composed of a motor 3, a driving gear 2 and a driven gear 1, and is suitable for equipment requiring power. The motor 3 and the driving gear 2 are tightly matched and provide power for them. There are 8 groups in total, that is, n=8. Eight driving gears 2 are arranged around the outer periphery of the driven gear 1, and mesh with the driven gear 1 respectively. All the driving gears 2 rotate synchronously and coordinately. Make passive gear 1 externally provide power. The whole device is supported by a fixed disc 6 .

Referring to Fig. 2, the number of groups of the motor 3 and the driving gear 2 of the gear drive device is two groups, namely n=2.

Referring to Fig. 3, the number of groups of motor 3 and driving gear 2 of this gear drive device is three groups, namely n=3.

Which of the above forms is more suitable for equipment can be determined according to actual needs. For equipment that requires a large driving force, a gear drive device with a larger n can be selected, and for equipment that requires a smaller driving force, a gear drive device with a smaller n can be selected.

Referring to Figure 4, the gear drive device is composed of a motor 3, a driving gear 2 and a driven gear 1. The number of groups of the motor 3 and the driving gear 2 is 8 groups, that is, n=8.
