18Right angle worm gear reducer is a simple device widely used in manufacturing equipment. Like almost all gears, enclosed worm gear drives require appropriate lubrication. It is these two factors that are the most common causes of premature failure of worm gear reducers. Lack of lubrication and incorrect use of lubrication are the two main causes of gearbox failure.
1、 Lack of lubrication
One of the common faults of worm gear reducers is that the unit runs dry without lubrication. Gearbox manufacturers typically transport equipment in a dry manner without lubrication. There are several reasons for doing this. Firstly, the increased weight of lubricants will increase transportation costs, and in larger gearboxes, the weight may be significant. Secondly, many manufacturing factories have standardized specific lubrication suppliers. Although many lubricants can be interchanged, they should not be mixed for use. Transporting a dry unit allows end-users to ensure universality within their facility.
Novice installers may overlook or ignore reading labels, labels, and installation manual warnings indicating that there is no lubrication in the gearbox, and start the transmission system without lubrication in the gearbox. The idle device will quickly damage the bronze worm gear. Even if lubricating oil is added afterwards, this damage is permanent and the gearbox must be replaced or rebuilt. There is no way to 'cure' damaged equipment.
2、 Insufficient lubricating oil
A related issue is insufficient lubrication. The most common installation method for worm gear reducers is called worm gear. This means that the worm gear is located above the bronze gear. In worm gear super orientation, the gearbox requires a certain level of lubricating oil. The reducer component can be installed in the worm gear in a directional manner.
The problem is that additional lubrication is required when the gearbox is installed under the worm gear. The structure inside the reducer and the way lubrication moves with the gears require up to 5096 extra lubrication for units installed below the worm gear compared to units installed above the worm gear. Not increasing the lubrication amount will mean that the bearings on the output shaft will dry out and fail in a shorter period of time.
For any given reducer, as long as the appropriate lubrication level is maintained, there is no physical reason why it cannot be installed above or below the worm gear. One of the problems caused by insufficient lubrication is that the malfunction does not occur immediately. The device will perform well for a period of time, which may be several weeks or months, depending on the application. Therefore, technicians may not be able to establish a connection between insufficient lubricating oil and equipment failure, and may therefore repeat errors.
It is relatively easy to determine how much lubrication is required for a given worm gear reducer in a specific installation direction. Transmission manufacturers include this information in their catalogs, manuals, and websites. In addition, all application support personnel can be contacted by phone, and many also have on-site sales personnel who can provide guidance.
