What is a good solution for the faulty gear reducer?

Because of the harsh working environment of Gear Reducers, defects such as wear and leakage are often found.

Common faults of Vertical/Horizontal gear reducer:

Gear Reducers usually presents problems such as wear and leakage in long-term operation, and the most important ones are:

  • Wear of Gear Reducers bearing room, which includes wear of shell bearing box, inner bore bearing room and gearbox bearing room.
  • Gear Reducers Gear shaft diameter wear, the primary wear place is the shaft head and keyway, etc.
  • Gear Reducers drive shaft bearing position is worn.

A solution after the failure of Vertical/Horizontal Gear Reducers

Aiming at the problem of Gear Reducers wear, the traditional treatment method is to repair welding or brush plating and then use machining to correct it, but both of them have disadvantages: the thermal stress caused by high temperature replacement welding cannot be completely eliminated, and it is easy to form raw material damage, leading to zigzags or cracking of components; And brush plating by coating thickness constraints, simple drop, and the above two methods are metal to correct the metal, can not change the “hard to hard” cooperation in all aspects of the impact of factors, will still form again wear. If some large bearing enterprises need to repair Gear Reducers, it is impossible to deal with it on site with these two methods, so it mostly needs to rely on external modification.

However, the modification with polymer composite materials will not cause the problem of secondary wear. It has super adhesion, excellent compressive strength and other functions. The use of polymer composite materials to correct, can be disassembled, free from machining (no welding thermal stress), the thickness of the correction is not restricted, can absorb the impact of the equipment shock, avoid re-wear, and greatly extend the service life of equipment components, for the enterprise to save a lot of downtime, play a huge economic value.

For the leakage problem, the traditional method needs to open and open the reducer, replace the gasket or change the sealant, not only time-consuming and laborious, and difficult to ensure the sealing effect, in the work will again present the problem of leakage. The polymer composite material could manage the leakage on site, and the Gear Reducers leakage problem was well dealt with by the company with excellent adhesion, oil resistance and tensile degree of 350 percent, overcoming the impact of vibration formation of reducer.

How to adjust the rotate speed of DC gear motors?

VEER Motor focus on the R&D and production of right-angle reduction gear motor for more than 12 years, with rich experience.

  1. The rotate speed of DC gear motor can be adjusted by yourself. If the gear motor is not DC gear motor, which the rotate speed can be adjusted by DC supply power with adjustable voltage function. The voltage of supply power high or low will affect the rotate speed of DC gear motor.
  2. There are different of reduction speed with adjustment speed of DC gear motor. Adjusting rotate speed, which is changing the voltage of supply power or changing the parameters of drive circuit of DC motor, then to achieve the purpose of adjusting the rotate speed. But for reduction speed (in most cases), which is installed a gearbox with some gear ratio on the end of output shaft of motor, then to reduce the rotate speed, but at the same time increase torque.
  3. DC motor is divided into brush motor and brushless motor, the former can be adjusted by changing the voltage of supply power; the voltage of the latter supply must be constant, and the rotate speed is adjusted by driver.
  4. There are two kinds of drivers of brushless DC motor: built-in and built-out. For built-in type, which cannot be adjusted the rotate speed, but the rotate speed of built-out type can be adjusted or not, which depends on the internal structure of drive.
  5. Magnetic DC motor is brush motor mostly. If rated operational voltage is 12v, you can use the 0~12v of DC stabilized power supply to power, and then the motor can be adjusted speed in stepless situation.

How to calculate gear ratio of gear reduction motor?

The “reduction” or gear ratio is calculated by dividing the number of teeth on the large gear by the number of teeth on the small gear. For example, if an electric motor drives a 13-tooth pinion gear that meshes with a 65-tooth gear, a reduction of 5:1 is achieved (65 / 13 = 5). If the electric motor speed is 1,500 rpm, the gearbox reduces this speed by five times to 300 rpm. If the motor torque is 10 lb-in, the gearbox increases this torque by a factor of five to 50 lb-in (before subtracting out gearbox efficiency losses).

The contrast between geared DC motor and geared AC motor

Geared DC motors can be defined as an extension of DC motor which already had its Insight details demystified. DC Motors convert electrical energy (voltage or power source) to mechanical energy (produce rotational motion). They run on direct current. The DC motor works on the principle of Lorentz force which states that when a wire carrying current is placed in a region having magnetic field, then the wire experiences a force. This Lorentz force provides a torque to the coil to rotate. A geared DC Motor has a gear assembly attached to the motor. The speed of motor is counted in terms of rotations of the shaft per minute and is termed as RPM. The gear assembly helps in increasing the torque and reducing the speed. Using the correct combination of gears in a gear motor, its speed can be reduced to any desirable figure. This concept where gears reduce the speed of the vehicle but increase its torque is known as gear reduction. This Insight will explore all the minor and major details that make the gear head and hence the working of geared DC motor.

Know more purpose and application of gear reduction motor, please contact VEER Motor

What are the purposes of a gear reduction motor?

Gear Reduction Motor is a gearbox that connects devices or drive machines. The main transmission structure is integrated and assembled by drive motor, shaft, and gearbox, which has the functions of connecting, transmission, deceleration, increase torque, and etc.
Principle of deceleration of gear reduction motor is to achieve the purpose of deceleration, which driving power of high-speed is from driving source to pass the power to output shaft of reducer by input shaft. Because the number of teeth of motor is more than gearbox, so the rotate speed is reduced, and the torque is increased. The main function of gear reduction motor is reducing the speed of motor, and increase torque by gear ratio.

Gear types in the internal of gear motor you should know

Gears are identified by many types and there are many specific technical words to describe their definition. The most common way to classify gears is by category type and by the orientation of axes.
Gears are classified into 3 categories: parallel axes gears, intersecting axes gears, and nonparallel and nonintersecting axes gears.
Spur gears and helical gears are parallel axes gears. Bevel gears are intersecting axes gears. Screw or crossed helical, worm gear and hypoid gears belong to the third category. Table 1.1 lists the gear types by axes orientation.
