The preventive maintenance and maintenance of elevator, in time discovery and elimination accident potential.
Wherein, reducing the common method of parts wear is exactly to lubricate components, but lubricating oil types in the market are numerous
More, oiling mode is also had nothing in common with each other, and people is allowed to be difficult to select, so that maintenance personnel do not have the maintenance of mine hoist
It targetedly safeguards in place；Therefore how suitable lubricating oil targetedly to be selected to the difference position easy to wear of mine hoist
And daily maintenance and maintenance are carried out to mine hoist using suitable oiling mode, to extend mine hoist service life
It is mine hoist user of service's problem to be solved.
Summary of the invention
In order to make up for the deficiencies of the prior art, a kind of method extending mine hoist service life proposed by the present invention,
The present invention extends mine hoist service life by the use of low speed heavy load roller sliding bearing；Meanwhile the present invention passes through
Suitable lubricating oil targetedly is selected to the different positions easy to wear of mine hoist and is lubricated in a manner of suitable oiling, is had
The degree of wear for reducing mine hoist many places position easy to wear of effect reduces mine hoist part damage in position easy to wear
Bad probability is improved the service life of mine hoist.
The technical solution adopted by the present invention to solve the technical problems is：A kind of extension mine hoist of the present invention
The method of service life, the mine hoist include that main shaft bearing, rope-adjusting clutch, retarder, gear coupling, depth refer to
Show device cabinet, lead screw and nut, it is characterised in that：The method following steps of the extension mine hoist service life：
Step 1：Mine hoisting mainshaft bearing is changed to low speed heavy load roller sliding bearing；
Step 2：The side that the low speed heavy load roller grease for sliding bearing more finished changing in step 1 is squeezed into oil gun
Formula is oily, and lubrication is primary within every two days；
Step 3：After the completion of low speed heavy load roller sliding bearing lubricating in step 2, rope-adjusting clutch is lubricated
Rouge is oily in such a way that oil gun is squeezed into, and lubrication is primary daily；
Step 4：After the completion of step 3 is to rope-adjusting clutch lubrication, to retarder with EP gear oil in No. 220 to fly
The mode for splashing lubrication is oily, and every shift lubrication is primary；
Step 5：After the completion of step 4 is to retarder lubrication, splashed with HL-30 gear oil profit to gear coupling
Sliding mode is oily, and every shift lubrication is primary；
Step 6：After the completion of step 5 is to gear coupling lubrication, to No. 30 machinery of depth indicator box house
Oil is oily in a manner of lubrication of splashing, and every shift lubrication is primary；
Step 7：After the completion of step 6 is to depth indicator box house lubrication, to No. 30 machinery of lead screw and nut
Oil is oily in a manner of smearing, and the every shift lubrication of lead screw is primary, and nut lubricates once daily；Wherein,
In step 1 used low speed heavy load roller sliding bearing include inner ring, it is outer ring, roller one, roller two, close
Seal and screw, the outer ring are set on inner ring；The diameter of the roller one is greater than the diameter of roller two, and roller one is located at interior
Between circle and outer ring, and roller one is adapted with inner ring；The roller two is between inner ring and outer ring, and roller two and roller
One arranged for interval；The sealing ring is sealed in the end face of inner ring and outer ring, and sealing ring is fixedly connected with inner ring by screw, sealing
Circle and inner ring are rotatablely connected with respect to outer ring.
Naturally recessed formation recess portion is provided between toothed projections and toothed projections on the outer wall of the inner ring；The tooth form
The top setting fluted one of protrusion；The roller one is located at recess portion and roller one and recess portion linear contact；The roller two
In groove one at the top of toothed projections, and roller two is in rolling contact with groove one.When work, roller one and recess portion roll and connect
It connects, roller one and recess portion linear contact, the bottom of recess portion are not contacted with roller one, and recess portion is suitable for the different roller of a variety of internal diameters
One；Roller two is in rolling contact with groove one, and the bottom of groove one is not contacted with roller one, and it is different that groove one is suitable for a variety of internal diameters
Roller two；Entire low speed heavy load roller sliding axle can be changed by changing different roller one and roller two and outer ring
The interchangeability of the outer diameter held, inner ring is strong.
