Description
Technical field
The utility model is related to equipment technology field of transport, more particularly to a kind of novel load-carrying universal wheel.
Background technology
It is transported in factory, transhipment large-scale workpiece is realized often by simple trailer and fork truck class dynamic power machine.In order to
It turns to and conveniently usually uses one group（2-4）Universal wheel does weight carrying.General common universal wheel bearing capacity is less than 1 ton,
Need to transport the universal wheel that larger or heavy objects user wishes to bigger bearing capacity for some.
Invention content
The utility model provides a kind of novel load-carrying universal wheel, can not be carried out for existing universal wheel larger or heavier
The problem of object carries.
To achieve the goals above, the technical solution of the utility model is specific as follows：
A kind of novel load-carrying universal wheel, including two web, wheel shaft, wheel hub, bearing I, the wheel rims being oppositely arranged, described two
Wheel shaft is installed in cooperation on a web being oppositely arranged, and is coordinated by bearing I on the wheel shaft and is installed wheel hub, set outside the wheel hub
Set wheel rim, described two web top setting load carriers being oppositely arranged.
The bearing I is deep groove ball bearings.
The outside of bearing I on the wheel shaft is both provided with washer I.
Described two opposite set is fixed in described wheel shaft one end by mounting gasket II, spring lock washer, hex nut
On the web set.
The load carrier includes bearing block, base flange, pin, bearing II, bearing III, nut, the bearing block
Bearing II is set in upper groove, bearing III is set in the lower groove of the bearing block, base flange is arranged in the bearing block top,
The base flange is connect with bearing block by pin.
The pin bottom cooperation installation nut, the pin bottom is provided with pin hole, nut is provided on the nut
Slot, split pin are inserted by the nut groove in the pin hole.
The bearing II is thrust ball bearing, and the bearing III is taper roll bearing.
The wheel shaft is 60mm with pin centre-to-centre spacing.
The utility model has the beneficial effects that：The failure mode of universal wheel occurs mainly in the support base position of wheel, this
Using pin, bevel welds patent up and down with base flange, enhances the bending resistance of pin, bearing II selects thrust ball axis
Hold, bearing III select taper roll bearing, axial direction and Radial resistant force can be overcome, due between inner hole of bearing seat and pin there are
Enough gaps will not make lower plane weld seam have an impact the rotation of bearing block, and wheel shaft is 60mm with pin centre-to-centre spacing, preferably
Ground is realized flexibly turns to ability under heavy duty（More than this eccentricity, universal train bears bigger bending moment, and is unfavorable for the load-carrying of train
Ability is less than this eccentricity, and influence train flexibly turns to ability）, the design overall dimension is proper, does not show too fat to move, opposite bank
Product is smaller, and bearing capacity is strong, and the lower rotation of heavy duty is flexible, and service life is long.

Specific implementation mode
As shown in Figure 1 to Figure 3, a kind of novel load-carrying universal wheel, including two web 3, wheel shaft 5, the wheel hubs being oppositely arranged
4, bearing I 10, wheel rim 11, bearing I 10 are deep groove ball bearings, and 5 one end of wheel shaft passes through mounting gasket II 13, spring lock washer
14, hex nut 15 is fixed on two webs being oppositely arranged 3, coordinates installation wheel hub 4, wheel hub by bearing I 10 on wheel shaft 5
Wheel rim 11 is arranged in 4 outsides, and load carriers are arranged in two 3 tops of web being oppositely arranged, and the outside of the bearing I 10 on wheel shaft 5 is equal
It is provided with washer I 12, load carrier includes bearing block 1, base flange 2, pin 6, bearing II 7, bearing III 8, nut 9, described
Bearing II 7 is set in the upper groove of bearing block 1, bearing III 8,1 top of the bearing block are set in the lower groove of the bearing block 1
Base flange 2 is set, and the base flange 2 is connect with bearing block 1 by pin 6,6 bottom of pin cooperation installation nut 9, described
6 bottom of pin is provided with pin hole, and nut groove is provided on the nut 9, and split pin is inserted into the pin hole by the nut groove
Interior, bearing II 7 is thrust ball bearing, and the bearing III 8 is taper roll bearing, and the wheel shaft 5 is with 6 centre-to-centre spacing of pin
60mm。
The failure mode of universal wheel occurs mainly in the support base position of wheel, and this patent is using pin 6 and base flange 2
Upper and lower bevel welding, enhances the bending resistance of pin 6, and bearing II 7 selects thrust ball bearing, bearing III 8 to select circular cone rolling
Sub- bearing can overcome axial direction and Radial resistant force, since there are enough gaps between 1 endoporus of bearing block and pin 6, will not make
Lower plane weld seam has an impact the rotation of bearing block 1, and the width of web 3 is more than wheel hub 4, and 4 both sides of wheel hub respectively add 10.5mm to pad
I 12 are enclosed, being freely rotated between web 3 of wheel hub 4, the bearing load of all of above selection is kept to be held by mechanical handbook dynamic loading
2 tons of abilities are carried to select, 2 thickness of base flange uses 30mm steel plates, when retain between ensureing about 6 weld seam of pin centainly away from
From（Distance is bigger, and bending resistance effect is better, and bearing capacity is bigger）, second is that ensureing and reliable bonding strength, wheel shaft 5 under heavy duty
With 6 center deviation 60mm of pin, preferably realizes and flexibly turn to ability under heavy duty（More than this eccentricity, universal train is born more
Big moment of flexure is unfavorable for the lifting capacity of train；Less than this eccentricity, influence train flexibly turns to ability）, the design due to
It is that practice transformation for many years is formed, overall dimension is proper, and not aobvious too fat to move, relative volume is smaller, and bearing capacity is strong, the lower rotation spirit of heavy duty
Living, service life is long.
