What are the types of gear motors?
There are three types of gear motors, including a right-angle gear motor, a parallel-shaft motor, and an inline gear motor.
- The inline gear motor is fully metric and is suitable for vertical and horizontal drive applications. These are coaxial motors where the output shaft is aligned with the motor shaft and is used for high-torque and slow-speed applications.
- The right-angle gear motor is designed with an electric motor and a gear reducer. It has an output shaft installed at 90 degrees to the input shaft. This gear motor is used for automated equipment, particularly with high torque requirements and limited space.
- Parallel shaft gear motors utilize gears to achieve speed reduction. The speed reducer shaft and motor shaft are installed on parallel planes. This motor is usually used in agitators, carriage drives, and conveyors.
What must be considered when choosing a gear motor?
A gear motor is a cost-effective and simple solution for low-speed and high-torque applications. However, choosing a reliable gear motor can be a challenging and complicated process.
Here are some key points to consider:
- Torque: If the gear motor is to be used for intensive loads, you have to select a motor with higher torque.
- AC DC Motor: The AC motor offers noiseless and smooth operations and can operate at high speeds. A DC motor is suitable if you constantly need high torque.
- Battery Voltage: The battery voltage depends on the application. A higher battery voltage increases the power and torque of the motor and improves power consistency, but will cost more.
What are the typical applications of a gear motor?
Gear motors are used where power and space are limited, given their modular and relatively compact design. They are used commonly in the automotive industry, the food production industry, and the manufacturing industry. Gear motors are installed in robots, handling and packaging machines, and in general multi-purpose equipment, among other applications.
What are common problems with a gear motor?
Gear motors are susceptible to issues from the environment. Despite the lip sealing, gear motors installed in harsher environments are likely to sustain damage over time, resulting in lubricant leaks or heat dissipation. This will affect the gear motor’s efficient operation. Moreover, thermal cycling may result in internal compression, which could cause warping, misalignment, or torque issues.
What type of maintenance or cleaning does a gear motor require, and how often?
Here are some important maintenance and cleaning tips to consider for maintaining gear motors:
- The gear motor must be lubricated regularly to extend its lifespan and improve performance. Besides, lubrication eliminates dry friction (which can cause component damage).
- The gear motor must be cleaned regularly because debris and dust layers on the motor can cause overheating.
- Regularly check the O-rings and seals to prevent oil leakage.
Which gear motor components need the most attention?
- Main Shaft: It rotates at the machine’s speed and carries power from the countershaft to the universal shaft.
- Gears: They transmit power and torque from one shaft to another.
- Bearings: They are important to support the rotary motion as they support the revolving components to reduce friction.
What are the main considerations when selecting a gear motor?
- Dimensional Requirements: They are essential to determine the limitations of space design. You have to check for space availability for the mounting shafts and profile shifting between shafts.
- Physical Requirements: These impact the gear motor’s performance. For this purpose, you have to consider the desired speed (it changes with the number of teeth), torque, power, speed, and the force transmission vectors.
