Abstract
The utility model provides a cover is collected to lubricating oil, establish at the epaxial dustcoat of transmission including the cover, the cover mouth of dustcoat constitutes sealed cooperation and rather than fixed connection with the casing outside of skeleton oil blanket outer fringe transmission equipment, and the oil return opening has been seted up to the lower extreme of dustcoat. Collect the lubricating grease of the seepage of skeleton oil blanket department to the oil return opening through setting up the dustcoat in the above-mentioned scheme, the staff place one in oil return opening below connect the oil box regularly clear up can, the greasy dirt can not pollute peripheral equipment like this, connect the waste oil in the oil box also can be applied to on other equipment that require not high to the lubricity degree.
Description
Technical Field
The utility model relates to a recycle field of equipment lubricating oil specifically is exactly a lubricating oil collection cover.
Background
Lubricating grease is generally required to be added to gears and bearings inside a shell of transmission equipment such as a transmission gear and a speed reducer, and a transmission mechanism is generally provided with a transmission shaft connected with external equipment, so that oil leakage can occur at a gap between the transmission shaft and the shell.
As shown in fig. 1, in the prior art, the leakage of lubricating grease is prevented by a framework oil seal sleeved on a transmission shaft. However, the phenomenon of slight leakage still occurs, even under the action of equipment vibration and complex factory environment, the framework oil seal is easy to damage and lose efficacy, and a large amount of lubricating grease can be leaked when field workers do not find the leakage in time. Therefore, the transmission equipment is easy to wear, the leaked lubricating oil pollutes the periphery, and the leaked lubricating oil cannot be recycled, so that the resource waste is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can carry out recycle's lubricating oil collection cover to the lubricating oil that skeleton oil blanket department leaked.
In order to achieve the purpose, the invention adopts the technical scheme that: a lubricating oil collecting cover comprises an outer cover sleeved on a transmission shaft, a cover opening of the outer cover and the outer side of a shell of framework oil seal outer edge transmission equipment form sealing fit and are fixedly connected with the outer cover, and an oil return opening is formed in the lower end of the outer cover.
Collect the lubricating grease of the seepage of skeleton oil blanket department to the oil return opening through setting up the dustcoat in the above-mentioned scheme, the staff place one in oil return opening below connect the oil box regularly clear up can, the greasy dirt can not pollute peripheral equipment like this, connect the waste oil in the oil box also can be applied to on other equipment that require not high to the lubricity degree.

Detailed Description
A lubricating oil collecting cover comprises an outer cover 10 sleeved on a transmission shaft 1, a cover opening of the outer cover 10 and the outer side of a shell 3 of a framework oil seal 2 outer edge transmission device form sealing fit and are fixedly connected with the outer cover, and an oil return opening 11 is formed in the lower end of the outer cover 10.
When oil leakage phenomenon appears in 2 departments of skeleton oil blanket in above-mentioned scheme, lubricating grease just can flow to the cavity between dustcoat 10 and the transmission shaft 1 in, then flows to the housing lower extreme under the effect of gravity, then flows out from oil return opening 11, and the staff places an oil receiving box in oil return opening 11 below and regularly clears up can, and peripheral equipment can not be polluted to the greasy dirt like this, and waste oil in the oil receiving box also can be applied to on other equipment that require not high to the lubricity.
The outer cover 10 is a half structure formed by two half bodies, and the oil return port 11 is arranged on the lower half body of the outer cover 10. The half-type structure is convenient for reforming the existing equipment transmission shaft and additionally installing the outer cover 10, is convenient and quick, and avoids the situation that more equipment is dismantled and the outer cover 10 can be installed.
An annular half flat gland 20 is fixedly arranged between the outer cover 10 and the shell 3, an annular sealing belt 21 is arranged between an inner ring of the half flat gland 20 and the transmission shaft 1, and sealing rings 40 are arranged on binding surfaces of the half flat gland 20, the outer cover 10 and the shell 3. The arrangement of the half flat gland 20 ensures the sealing between the outer cover 10 and the shell 3, prevents lubricating oil from flowing out of the outer cover 10 from a gap, and simultaneously the sealing belt 21 further enhances the sealing effect and reduces the oil leakage at the framework oil seal 2.
The outer cover 10 is internally provided with a half type oil blocking sleeve 30 which is sleeved on the transmission shaft 1, one end of the oil blocking sleeve 30 is fixedly connected with the half flat gland 20, the other end of the oil blocking sleeve 30 is spaced from the outer end cover 12 of the outer cover 10, and a sealing ring 40 is arranged between the end surface of the oil blocking sleeve 30 and the plate surface of the half flat gland 20. Lubricating grease can contact with oil baffle sleeve 30 earlier when flowing along transmission shaft 1, then falls to the dustcoat 10 below from oil baffle sleeve, and oil baffle sleeve 30's setting has avoided lubricating grease to flow out to the external world along transmission shaft 1.
At least two annular oil absorption felts 31 are arranged between the oil blocking sleeve 30 and the transmission shaft 1, and oil leakage holes 32 are formed in the lower end of the oil blocking sleeve 30 between the adjacent oil absorption felts 31. The lubricating grease flowing to the gap between the oil baffle sleeve 30 and the transmission shaft 1 can be absorbed by the oil-absorbing felt 31, so that the lubricating grease is prevented from flowing further along the transmission shaft 1, and the lubricating grease can also flow out of the oil leakage hole 32 when the oil-absorbing felt 31 absorbs excessive oil.
The outer cover 10 is a conical cover with a small outer end and a large inner end. This facilitates the collection and outflow of the lubricating grease.
A sealing ring 13 is arranged between the outer end cover 12 of the outer cover 10 and the transmission shaft 1. This further seals the housing 10 to prevent the grease from splashing into the environment and contaminating the surrounding environment.
