Description
Technical field
This utility model is related to a kind of wheel, more particularly to a kind of wheel for heavy carrying dolly, belongs to heavy
Load bearing equipment.
Background technology
, generally by the way of taper roll bearing rotation, this structure is for small-sized, light for the wheel mechanism carrying dolly
Carry, for the good situation of work condition environment can normal work, the service life of bearing also can reach operating limit, but for big
For the poor situation of type, heavy duty, work condition environment, the service life of bearing greatly shortens, and the lighter is the damage of bearing, severe one meeting
Injure wheel, thus leading to scrapping of a whole set of wheel.
Content of the invention
The purpose of this utility model is to provide that a kind of structure is simple, long service life, can self-lubricating, ensure that wheel is steady
Fixed, reliability service the wheel for heavy carrying dolly.
Technical solution：
This utility model includes：Wheel, the both sides of wheel inner holes are provided with bearing, and described bearing adopts self-lubricating copper sheathing axle
Hold, self-lubricating copper sheathing bearing carries the axle sleeve of ring flange for one end.
Described self-lubricating copper sheathing bearing adopts inserted graphite copper sheathing.
The assembling mode of the cylindrical and wheel inner holes of described self-lubricating copper sheathing bearing is interference fits.
The described endoporus of self-lubricating copper sheathing bearing is coordinated for gap with the assembling mode of rotating shaft.
This utility model adopts self-lubricating copper sheathing bearing to replace taper roll bearing.
This utility model using self-lubricating copper sheathing bearing compared with traditional taper roll bearing, self-lubricating copper sheathing bearing
Through actually used contrast, large carrying capacity, uniform force, find that taper roll bearing will damage for about three months about,
Self-lubricating copper sheathing bearing service life nearly 1 year；Taper roll bearing needs are often oily simultaneously, and self-lubricating copper sheathing
Bearing does not need extraneous intervention lubrication.
This utility model, due to the raising of service life, decreases the replacing of spare part, has not only saved cost, has also made simultaneously
Maintenance, the cycle stretch-out safeguarded, reduce labor intensity, improve production efficiency, simultaneously self-lubricating function of the present utility model,
Ensure that wheel reliably and securely runs.

Specific embodiment
This utility model includes:Wheel 1, rotating shaft 2, self-lubricating copper sheathing bearing 3.
This utility model bearing adopts self-lubricating copper sheathing bearing 3, and described self-lubricating copper sheathing bearing 3 carries ring flange for one end
Inserted graphite copper sheathing, self-lubricating copper sheathing bearing 3 is respectively placed in the both sides of wheel 1 endoporus, self-lubricating copper sheathing bearing 3 cylindrical
Assembling mode with wheel 1 endoporus is interference fits, and endoporus is coordinated for gap with the assembling mode of rotating shaft 2.
This utility model and car body assembling mode：
Rotating shaft 2 is passed through after the endoporus of self-lubricating copper sheathing bearing 3, one end is placed in the corresponding hole of car body 6, and the other end passes through
After the positioning sleeve 4 on car body 6, it is bolted, described two self-lubricatings fixing with car body 6 in the presence of baffle plate 5
The distance installation position corresponding with car body 6 between flange side surface after copper sheathing bearing 3 assembling coordinates for gap.
Wheel 1:
For heavy wall axle sleeve structure, its endoporus is assembled in the way of interference fits with self-lubricating copper sheathing bearing 3, accuracy class
K7, two end faces will ensure the perpendicularity with centrage, accuracy class 7-8 level.
Rotating shaft 2:
It is provided with the Length discrepancy multidiameter structure of retaining groove for one end, the middle part of axle is the big axle of multidiameter, with self-lubricating copper sheathing
Bearing 3 is assembled in the way of the cooperation of gap, accuracy class f6；The both sides of axle are little axle, its short-and-medium axle side and the car of multidiameter
Body 6 corresponding position assembles, precision h6, and major axis side is assembled with positioning sleeve 4, precision h6；Slot width is bigger than the thickness of baffle plate 5
0.5mm-1mm is advisable.
Self-lubricating copper sheathing bearing 3：
It is the axle sleeve structure with ring flange, there is inserted graphite, its cylindrical assembling mode with wheel 1 is joined for transition
Close, accuracy class h6, endoporus is coordinated for gap with the assembling mode of rotating shaft 2, accuracy class F7；The inside and outside end of ring flange to be ensured
Face and the perpendicularity of centrage, accuracy class 7-8 level.
Positioning sleeve 4：
For axle sleeve structure, cylindrical and car body 6 assembling mode is interference fit, accuracy class k6, endoporus and rotating shaft 2
Assembling mode is interference fits, accuracy class H7.
Baffle plate 5：
For plate structure, it is provided with the through hole corresponding to car body 6 upper screwed hole.
Use of the present utility model, improves the service life of wheel, extends the parts replacement cycle, decrease maintenance,
Maintenance time, eliminating the operation of hand oiling lubrication, thus reducing production cost, reducing labor intensity it is ensured that heavy type is held
Carry car safety, reliably run.
