Worm Motors

NRV-F worm gearbox is a worm gear reducer with shaft input and square flange output. Different models of RV worm reducers have different flanges, which can be docked with matching flange-type shaft holes. The standard output flange is a short output flange (FA), and a long output flange (FB) is also available. HZPT provides a wide range of worm gear reducers products and information for the majority of our agents, helps them formulate marketing plans, provides the most competitive prices and high-quality products, and achieves win-win cooperation.

How to Choose a Worm Gear Reducer?

When choosing a worm gear reducer, there are several factors to consider:
(1) Rated torque: The amount of torque that the reducer can handle is an important factor in determining the appropriate size and type of worm gear reducer for your application.
(2) Ratio: The gear ratio determines the speed reduction that the worm gear reducer will provide. This should be selected based on the desired speed of the output shaft.
(3) Size and weight: The size and weight of the worm gear reducer should be considered in relation to the space and mounting limitations of your application.

(4) Input speed: The input speed of the worm gear reducer should be selected based on the speed of the motor or other power source that will be driving it.
(5) Environmental factors: Consider the environment in which the worm gear reducer will be operating, such as temperature, humidity, and exposure to chemicals or other corrosive substances.
(6) Brand and Quality: Research the different brands and their quality, some brands may offer better warranty and service.


Worm Motors Reducer Lubrication Maintenance:

1. Selection of lubricants and additives. Worm gear reducers generally use 220# gear oil. For reducers with heavy loads, frequent starts, and poor use environments, some lubricating oil additives can be used to make the gear oil still adhere to the gear surface when the worm gear reducer stops running, forming a protective membrane to prevent heavy load, low-speed, high torque and direct contact between metals when starting. The additives contain a seal ring regulator and anti-leakage agent to keep the seal ring soft and elastic and effectively reduce lubricating oil leakage.

2. Establish a lubrication maintenance system. The worm gear reducer can be maintained according to the "five fixed" principle of lubrication work, so that every reducer has a person responsible for regular inspections, and it is found that the temperature rise is obvious if the temperature exceeds 40 ℃ or the oil temperature exceeds 80 ℃, the quality of the oil decreases or the oil If you find too much copper powder and produce abnormal noise, you should stop using it immediately, check and repair it in time, eliminate the fault, and replace the lubricating oil. When refueling, pay attention to the amount of oil to ensure that the reducer is properly lubricated. The gearbox cleaning and maintenance machine can also be used to clean the gearbox using the original oil supply and discharge system of the worm gearbox and filtered lubricating oil, without changing any hardware facilities of the gearbox, without adding any cleaning agent, ensuring the safe operation of the gearbox, extend the service life of the gearbox.

3. Ensure assembly quality. Some special tools can be purchased or made by yourself. When disassembling and installing the worm gear reducer components, try to avoid hitting with other tools such as hammers; when replacing gears and worm gears, try to use original parts and replace them in pairs; when assembling the output shaft, pay attention to tolerance matching; anti-sticking agent or red lead oil should be used to protect the hollow shaft to prevent abrasion, rust, or dirt on the mating area, which is difficult to disassemble during maintenance.
