Problems solved by technology

Because the two ends of the worm are sealed with a common skeleton rubber oil seal, the sealing effect is not good. With the high temperature and medium speed operation of the worm, the wear and melting of the skeleton oil seal will be aggravated, and the oil leakage will become more and more serious. On average, 0.5 more oil needs to be replenished every day. Kg, the average oil seal replacement cycle is 7 days / time, not only the equipment maintenance workload is heavy, the oil waste is large, and the site sanitation is affected

Embodiment Construction

[0016] The main purpose of the present invention is to solve the problem of severe oil leakage at both ends of the worm gear of a worm gear reducer operating at a high temperature and at a medium speed. The question of service life. Because the method of the invention effectively realizes plugging, the productivity is greatly improved, the waste of a large amount of oil is avoided, the maintenance workload of the equipment is reduced, and the on-site sanitation of the reducer is improved.

[0017] The oil leakage of the reducer can be roughly analyzed as oil leakage in two situations: dynamic and static. Dynamic means that the reducer is in operation, and static refers to the state of the reducer after it stops. The method for preventing oil leakage of the present invention adopts the combined scheme of three seals to solve the oil leakage in two different situations. The first seal mainly solves the oil leakage when the reducer is in dynamic state, and the second and third ...

Abstract

The invention relates to a method for preventing the oil leakage of a worm gear reducer, which comprises the following steps: arranging spiral seals on in-shaft covers at both ends of a worm screw to serve as first seals, respectively arranging second seals composed of high temperature resistant stuffing outside the two spiral seals, and arranging bidirectional dynamic oil seals composed of high temperature resistant and wear resistant materials to serve as third seals. The method for preventing the oil leakage of the worm gear reducer combines the spiral seals of non-contact type seal with contact type seals, and enables the reducer to be well sealed in both dynamic and static modes.

Description

technical field [0001] The invention belongs to a worm gear reducer, in particular to a method for preventing oil leakage at both ends of a worm gear of a worm gear reducer operating at a high temperature and at a medium speed. Background technique [0002] In the chemical industry, especially in the deep processing of manganese series products such as electrolytic manganese dioxide, manganese sulfate, and electrolytic metal manganese, ordinary worm gear reducers are often used as reducers for mixing chemical slurry or solution. This type of reducer is more suitable for It is used under harsh conditions such as heavy dust, severe acid and alkali corrosion, and high ambient temperature. The equipment is simple to manufacture, low in cost, and requires less effort in maintenance and replacement than other types of reducers, so it is favored by manufacturers. [0003] However, in the environment of high temperature and medium speed operation, serious oil leakage is also common ...
