Abstract
The utility model discloses a kind of variable speed fluid coupling main shaft oil enveloping structure of good airproof performance, it includes the main shaft being arranged on by rolling bearing on casing, it is characterized in that sealing shroud is provided with by jump ring on main shaft, sealing shroud is provided with O-ring seal close to rolling bearing one end, and gland is sleeved on sealing shroud and is bolted on casing；The utility model is simple in construction; good sealing effect, solve outside framework oil seal abrasion and aging etc. and oil leak problem occur, decrease user because variable speed fluid coupling often wants the time of maintenance shut-downs and changes the increased expense of spare part institute; cost is reduced, there is preferable economic benefit.
Description
Technical field
A kind of variable speed fluid coupling is the utility model is related to, specifically a kind of variable speed fluid coupling main shaft
Oil enveloping structure, more particularly to a kind of variable speed fluid coupling main shaft oil enveloping structure of good airproof performance.
Background technology
The main shaft oil enveloping structure generally use gland of existing variable speed fluid coupling adds the mode of outside framework oil seal to seal
For lubricating the lubricating oil of rolling bearing, after a period of time, due to the work on the spot environment ratio of variable speed fluid coupling
Relatively severe, often dust is more, the reasons such as corrosive gas is more, causes outside framework oil seal easily to wear simultaneously aging, meanwhile, main shaft and bone
The matching part of frame oil sealing is also often worn out seriously, and oil leakage phenomenon happens occasionally.And such as to change outside framework oil seal or repairing abrasion
Main shaft, it is necessary to variable speed fluid coupling complete machine is hung out, could be changed or be repaired.
The content of the invention
The purpose of this utility model is to provide a kind of variable speed fluid coupling main shaft oil enveloping structure of good airproof performance.
The utility model, which adopts the following technical scheme that, realizes its goal of the invention, a kind of variable speed fluid coupling main shaft
Oil enveloping structure, it includes the main shaft being arranged on by rolling bearing on casing, is provided with sealing shroud by jump ring on main shaft, seals
Set is provided with O-ring seal close to rolling bearing one end, and gland is sleeved on sealing shroud and is bolted on casing.
At least provided with a ring packing teeth on sealing shroud described in the utility model.
Due to preferably realizing goal of the invention using above-mentioned technical proposal, the utility model, its is simple in construction, sealing effect
Fruit is good, solves outside framework oil seal abrasion and aging etc. and oil leak problem occurs, decreases user because variable speed fluid coupling passes through
Often want the time of maintenance shut-downs and change the increased expense of spare part institute, reduce cost, there is preferable economic benefit.
Brief description of the drawings
Fig. 1 is the structural representation of prior art；
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
As shown in Figure 1, the oil enveloping structure generally use gland 7 of main shaft 1 of existing variable speed fluid coupling plus skeleton oil
The mode of envelope 11 seals the lubricating oil for lubricating rolling bearing 2, after a period of time, due to variable speed fluid coupling
Work on the spot environment it is more severe, often dust is more, the reasons such as corrosive gas is more, and causing outside framework oil seal 11, easily abrasion is simultaneously
Aging, meanwhile, the matching part of main shaft 1 and outside framework oil seal 11 is also often worn out seriously, and oil leakage phenomenon happens occasionally.And such as will be more
Change outside framework oil seal 11 or repairing abrasion main shaft 1, it is necessary to variable speed fluid coupling complete machine is hung out, could be changed or
Repairing.
As shown in Figure 2, a kind of variable speed fluid coupling main shaft oil enveloping structure, it includes being arranged on by rolling bearing 2
Main shaft 1 on casing 3, is provided with sealing shroud 6 on main shaft 1 by jump ring 8, and sealing shroud 6 is provided with O-shaped close to the one end of rolling bearing 2
Sealing ring 5, gland 7 are sleeved on sealing shroud 6 and are fixed on by bolt 4 on casing 3.
At least provided with a ring packing teeth 10 on sealing shroud 6 described in the utility model.
The present embodiment is provided with sealing shroud 6 on main shaft 1, and O-ring seal 5, sealing shroud are provided with close to the one end of rolling bearing 2
6 other ends are provided with jump ring 8, and sealing shroud 6 is provided with 2 ring packing teeths 10.Gland 7 is sleeved on sealing shroud 6 and by bolt 4
It is fixed on casing 3.During utility model works, sealing shroud 6 is rotated with the superhigh speed of main shaft 1 one, and lubricating oil is got rid of to gland 7
Inwall；Due to the effect of ring packing teeth 10, the structure in a similar labyrinth is formed between gland 7 and sealing shroud 6, to prevent to moisten
Lubricating oil leaks, and finally, lubricating oil flows back to casing 3 through the oil discharge outlet 9 on casing 3.
The utility model is simple in construction, good sealing effect, solves outside framework oil seal abrasion and aging etc. and oil leak problem occurs,
User is decreased because variable speed fluid coupling often wants the time of maintenance shut-downs and changes the increased expense of spare part institute, is reduced
Cost, has a preferable economic benefit.
