WPDKA Single Stage Cast Iron Worm Reducer

Features of WPDKA Series Worm Gearboxes:

1. Stable transmission, low vibration, impact, and noise, large reduction ratio, broad versatility, and suitable for use with various mechanical equipment.

2. Large transmission ratio can be obtained by single-stage transmission with a compact structure. Most reducers have suitable self-locking properties and can save the brake device for mechanical equipment requiring brakes.

3. The meshing friction loss between worm screw teeth and worm gear surface is relatively large, so the transmission efficiency is lower than that of the gear, it is easy to be heated, and the temperature is higher.

4. Higher requirements for lubrication and cooling.

5. Good interfitting. National standards manufacture the worm and worm.

What Are the Causes of Excessive Vibration of Worm Gearboxes?

1. Rotor mechanical unbalance
The imbalance mentioned here refers to the imbalance in the static state of the rotor and the imbalance in the rotating state. The rotor deviates from the axis, deflects, and produces abnormal vibration under centrifugal force.

2. Transmission disorder
When the calibration line between the motor and the driver in the worm gear reducer is not good, and it is easy to produce vibration, adjust the calibration line and reinstall the connection between the driver and the motor to stabilize the rotation of the motor bearing.

3. Loose rotor parts
Some parts of the motor rotor: commutator, magnetic pole, belt pulley, etc. Generally, in this case, the rotor will have noise. This looseness will also occur after the reducer has been used for a long time. These situations will be handled as soon as possible because the consequences will become more and more severe after a long time.

4. Large base vibration
In some cases, the excessive vibration of the base also impacts. The vibration frequency of the ground can be said to be the speed of the worm gear reducer. There may be a problem in the design of the base, resulting in an unstable state in operation.

5. Excessive bearing wear
When the bearing works for a long time, the bearing clearance is too large or unbalanced, resulting in bearing friction heating and friction between the rotor and stator, directly damaging the bearing. The sliding bearing is prone to vibration because it has the dense effect of lubricating oil; the machine shaft will float, which can also be related to the bearing weight. If the bearing weight is more significant, the wear will be faster.
