Description

Speed reducer for punching machine

Technical Field

The utility model relates to the technical field of stamping equipment, in particular to a speed reducer for a stamping machine.

Background

The speed reducer is a power transmission mechanism, does not generate power, and has the function of reducing the revolution number of a motor to the required revolution number by utilizing gears with different sizes and speed converters to obtain a mechanism with larger torque. The reason why the speed reducer is used instead of the motor directly connected to the equipment is that if the motor is directly connected to the equipment, when the equipment is operated, the load of the motor is very large, so that the damage to the motor is also large, and the speed reducer is not uniform, for example, the speed reducer with the speed reduction ratio of 100 has the speed ratio of input revolution/output revolution, and if the speed ratio is 100, the output torque is about 100 times of the input torque. The load on the motor when the machine is running (speed is reduced and torque is increased) is only one percent. Moreover, the speed reducer is damaged only by replacing the lower gear, and the cost is much lower than that of the motor.

However, the planetary reducer is complex in structure and not beneficial to subsequent installation and maintenance, only one input shaft can be connected with one driving motor, when the torque required by equipment exceeds the rated torque of the existing driving motor, the original driving motor cannot be used, and in most cases, when the ordinary reducer is used, the ordinary reducer needs to be matched with a primary reducer for use, so that the reducer is prevented from being burnt out due to overlarge initial load, and the time for installing and debugging the reducer is prolonged.

The number of the driving motors 110 can be determined according to the load required to be driven by the punching machine, the larger the load is, the more the number of the driving motors 110 can be set, and compared with the traditional speed reducer which can only be connected with one driving motor, the speed reducer provided by the utility model can simultaneously load a plurality of driving motors to work together, so that the structure of the speed reducer is simplified, and the use requirements of punching machines with different loads can be met.

The number of the third driven wheels 320 can be one, two, three or more, and the present solution is mainly described in detail for the case where there are three third driven wheels 320.

When the power output mechanism 400 is installed, a load is installed on the power output mechanism 400, when the power output mechanism starts to work, the driving motor 110 drives the main gear 120 to rotate, the main gear 120 drives the first driven wheel 210 which is meshed with the main gear to rotate, so that the first rotating shaft 220 drives the second driven wheel 310 which is coaxial with the first driven wheel 210 to rotate together, the second driven wheel 310 drives the third driven wheel 320 to rotate when rotating, and the third driven wheel 320 drives the power output mechanism 400 to rotate when rotating.
