Abstract
The utility model discloses an end cover of a cooling bed worm gear case speed reducer, which belongs to the technical field of worm gear case speed reducers and comprises a cover cylinder and a gland pressed at the end part of the cover cylinder, wherein a shaft hole is arranged between the cover cylinder and the gland, a flange plate is arranged outside the cover cylinder, a groove is arranged inside the cover cylinder, two layers of framework oil seals and a graphite packing are sequentially arranged from bottom to top in the groove, and the top of the cover cylinder is fixedly provided with the gland. The arrangement of the oil seal lip part can prevent iron filings such as iron scales from being accumulated in a large amount, so that oil leakage is avoided; meanwhile, the packing is arranged on the oil seal, so that the oil seal can be protected, and corrosion of spray water of a cooling bed can be reduced; and after the speed reducer is used for a long time, if the shaft end is worn, a shaft sleeve can be additionally arranged on the shaft in the later period, an oil seal is widened, and a small part of the shaft sleeve is replaced during assembly to protect the worm.
Description
Technical Field
The utility model relates to the technical field of worm gear case speed reducers, in particular to an end cover of a worm gear case speed reducer.
Background
The problem frequently encountered at present by the cooling bed worm gear case speed reducer is that oil leakage at the end cover is serious, the oil filling frequency is high, the oil consumption is large, the working intensity of personnel is high, the greasy dirt around the gear case is serious, and the dangerous coefficient of spot inspection operation is high. The working environment temperature of the cooling bed worm gear case speed reducer is high, iron oxide scale impurities are more, the cooling bed worm gear case speed reducer is used in a severe environment, the gland sealing abrasion amount is increased in the high-speed operation process of the transmission shaft, the cooling bed worm gear case speed reducer is an important cause of oil leakage of the worm gear case speed reducer, the service life of the oil seal is shortened due to corrosion of cooling bed spray water, the cooling bed worm gear case speed reducer is another important cause of oil leakage of the worm gear case speed reducer, on-site oil pollution is serious, oil consumption is improved, and the safety risk coefficient is increased in daily point inspection operation and maintenance operation.
Therefore, the end cover of the cooling bed worm gear case speed reducer can solve the problem of oil leakage.
Disclosure of Invention
Aiming at the problems in the prior art, the utility model provides the worm gear case speed reducer end cover, which improves the sealing effect of a gland.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
the end cover of the worm gear case speed reducer comprises a cover cylinder and a gland pressed at the end part of the cover cylinder, wherein a shaft hole is formed in the middle of the cover cylinder and the gland, a flange plate is arranged outside the cover cylinder, a groove is formed in the cover cylinder, two layers of framework oil seals and a graphite packing are sequentially arranged in the groove from bottom to top of the cover cylinder, and the gland is fixed at the top of the cover cylinder.
The technical scheme of the utility model is further improved as follows: the gland is fixed on the cover cylinder through bolts.
The technical scheme of the utility model is further improved as follows: the internal diameter of skeleton oil blanket is less than the external diameter of output shaft, after the installation, skeleton oil blanket and output shaft interference fit.
The technical scheme of the utility model is further improved as follows: the output shaft is provided with a shaft sleeve.
The technical scheme of the utility model is further improved as follows: the end cover is fixed on the speed reducer body through bolts penetrating through the flange plate.
By adopting the technical scheme, the utility model has the following technical effects:
the end cover of the speed reducer is internally provided with the two layers of framework oil seals and the packing, so that iron filings such as iron scales and the like can be prevented from accumulating a large amount of oil seal lip parts, and oil leakage is avoided; meanwhile, the packing is arranged on the oil seal, so that the oil seal can be protected, and corrosion of spray water of a cooling bed can be reduced; and after the speed reducer is used for a long time, if the shaft end is worn, a shaft sleeve can be additionally arranged on the shaft in the later period, an oil seal is widened, and a small part of the shaft sleeve is replaced during assembly to protect the worm.
