Abstract
The utility model relates to a high rotating speed roller for measuring pressure or tension, and mainly aims to solve the technical problem that the existing bearings of pressure (tension) measuring rollers are easy to corrode by corrosive liquid such as acids, alkalis and the like due to severe working environments. The technical scheme includes that the high rotating speed roller for measuring the pressure or the tension comprises a roll shaft, a roll sleeve and a shaft sleeve, and is characterized in that an impeller end cover is additionally arranged in the roll sleeve outside the shaft sleeve and fixed with a roll shaft end through a locknut, and an air chamber is formed by a cavity between the impeller end cover and the shaft sleeve. The roll shaft end is provided with an air channel communicated with the air chamber so as to increase air inletting force during rotation. The high rotating speed roller for measuring pressure or tension is suitable for high rotating speed operations and severe working environments such as a cold rolling mill where the roller is easy to corrode by corrosive liquid such as acids, alkalis and the like.
Description
Technical field
The utility model relates to a kind of high rotating speed pressure measurement (opening) power roller
,Be applicable to that high rotating speed and work under bad environment are subject to the workplace that corrosive liquids such as soda acid corrodes, high rotating speed pressure measurement (opening) the power roller that corrodes at corrosive liquids such as being subject to soda acid like cold rolling mill.
Background technique
At present; High rotating speed pressure measurement (opening) power roller that each tradition of domestic metallurgy industry is used because: work under bad environment is after corrosive liquids such as receiving soda acid corrodes, and its bad seals lost efficacy, and causes corrosive liquids entering bearing; Cause damage of bearings, cause the equipment failure shutdown.
The main at present erosion that relies on seal arrangement to stop corrosive liquids.Real work during often because of the roller high speed rotating the fine and close envelope of corrosive liquids such as soda acid damage that the back of losing efficacy gets into bearing and roll body causes equipment failure to be shut down.
Summary of the invention
The utility model purpose provides a kind of corrosive liquids that can prevent to get into the high rotating speed measuring pressure or the tension roller of bearing, mainly solves the bearing of present pressure measurement (opening) power roller because work under bad environment is subject to the technical problem of corrosive liquids erosions such as soda acid.
The technological scheme of the utility model: a kind of high rotating speed measuring pressure or tension roller, comprise roll shaft, roller shell and axle sleeve,
It is characterized in that: in the roller shell in the axle sleeve outside, install the impeller end cap additional, the impeller end cap is fixed through locking nut and roll shaft termination, and impeller end cap and shaft room cavity form air compartment.For increasing rotation air intake power, the roll shaft termination is established the air channel and is fed air compartment.
The beneficial effect of the utility model: owing to be provided with the impeller end cap; High rotating speed pressure measurement (opening) the power roller blast that high speed rotating produces when work can effectively stop the erosion of corrosive liquids; Simultaneously because of good wind circulating system is arranged, can guarantee that cooled roller is warm with the fricative high temperature of axle sleeve, height when high speed rotating.Thereby improved working life, reduction spare parts consumption, the raising equipment availability efficient of roller, reduced the downtime, had remarkable economic efficiency.

Among the figure: 1, impeller end cap; 2, air channel; 3, locking nut; 4, air compartment; 5, axle sleeve; 6, roll shaft; 7, roller shell; 8, roll shaft termination.
Embodiment
With reference to Fig. 1,2; A kind of high rotating speed measuring pressure or tension roller comprise roll shaft 6, roller shell 7 and axle sleeve 5, in the roller shell 7 in axle sleeve 5 outsides, install impeller end cap 1 additional; Impeller end cap 1 is fixing with roll shaft termination 8 through locking nut 3, and the cavity between impeller end cap 1 and the axle sleeve 5 forms air compartment 4.For increasing rotation air intake power, roll shaft termination 8 is established air channel 2 and is fed air compartment 4.
During use; Produce blast through rotating roll shaft 6 impeller end caps 1 high speed rotating; Rely on blast to stop corrosive liquids to damage sealing; Simultaneously form wind circulating system by air channel 2, air compartment 4, impeller end cap 1, cooling air from the axle head air channel 2 air intakes to air compartment 4 and through 1 air-out of spiral shell impeller end cap to reach the circulation cooling effect.Can cool off reduction effectively because of roller shell 7, roll shaft 6 high speed rotating and axle sleeve 5 fricative high temperature, high heat.
Claims (2)
