According to the old wheel and axle, take care not to hurt the plastic fork of the wheel.
Install the new wheel and axle nails, with a brick pad, the hollow rivet-like place with round steel punch flat flare can be.
Universal wheel
Universal wheel is the so-called movable caster, its structure allows horizontal 360-degree rotation. Caster is a general term, including movable casters and fixed casters. Fixed casters have no swivel structure, can not rotate horizontally only vertical rotation. These two kinds of casters are generally used in conjunction with, for example, the structure of the cart is the front of the two fixed wheels, the back near the push handrail is two movable universal wheel. Universal wheel is installed in the caster wheel bracket can be in the dynamic load or static load horizontal 360 degrees rotation. There are many kinds of materials used to manufacture the universal wheel, the most common materials are: nylon, polyurethane, rubber, cast iron and other materials. They are widely used in many industries and various fields such as mining, mechanical equipment, electronic equipment, medical equipment, engineering decoration, textile, printing and dyeing, furniture, logistics equipment, storage, turnover trucks, chassis, cabinets, equipment, electromechanical, clean room, production lines, large supermarkets and so on. According to its different uses, the bearing is divided into iron core, aluminum core, plastic core, size 1 inch to 8 inch ranging. Among them, iron core, aluminum core is generally heavy-duty bearing wheel, the use of often equipped with brake apparatus.
1 classification
Universal wheel (mecanum wheels), which is a tradition with many roller circumferential wheel, roller plate in a plane parallel to the wheel rotation axis wheel at 45 ° axis of rotation. Universal wheels are able to move in any direction using standard chassis shapes. 100mm universal wheels (mecanum wheels)-W092 right
Mecanum wheels (Mecanum wheels) it can move in any direction.
It should be used with three other universal wheels (2 left, 1 right). Roller ball bearings are mounted for smooth rolling.
100mm universal wheel (mecanum wheels) - W087 left
100mm universal wheel (mecanum wheels) left should be used with three other universal wheels (1 right, 2 left). Roller ball bearings are mounted, making it roll out very fluidly.
203mm Mecanum wheels in a set of (4) 14128
The 203mm universal wheel (mecanum wheel) is a heavy duty wheel. A series of rollers make up each wheel, mounted so that their axis of rotation is 45 to the axis of the main wheel. synchronized with the rotation of the wheels, the rollers enable sideways movement in the vehicle moving forward or backward normally, but in the opposite direction of the wheel pairs by spinning. Put them together and can move laterally, diagonally, or turn in a circle.
203mm mecanum wheel (mecanum wheel) right-14127
The 203mm mecanum wheels are a heavy duty wheel.
203mm universal wheel (mecanum wheel) left-14126
203mm universal wheel (mecanum wheel) is a heavy duty wheel.
Set of 100mm cardan wheels (mecanum wheels)
Set of cardan wheels (mecanum wheels) including 4 wheels
152mm cardan wheels (mecanum wheels)-W099 right
152mm cardan wheels (mecanum wheels should be used in conjunction with three other universal wheels (2 left, 1 right).
152 mm mecanum wheels (4 pcs) W101
Set includes 4 152 mm mecanum wheels.
152mm Mecanum Wheels - W095 Left
152mm Mecanum Wheels should be used with the other three Mecanum Wheels (1 Left, 2 Right).
2Correct use
1The casters must be mounted in the position for which the manufacturer has indicated the design.
2, the installation of the caster bracket must have sufficient strength, to meet the use of the weight-bearing.
3, the function of the casters can not be changed, and is not affected by the mounting device.
4. The axle of the transit wheel must always be vertical.
5, fixed casters must be in a straight line with their axles.
6, if both use only swivel casters, they must be consistent.
7. If fixed casters are used in conjunction with swivel casters, then all casters must be compatible with each other and must be recommended by the manufacturer.
3 overhaul method
1, test the tire tread visible wear. Tire surface "wear point" can imply the accumulation of foreign matter, such as wire and other debris may be wrapped around the wheel, remove the wheel on the bolt and nut, clean up debris. Check whether the wheel bearing is broken, if the parts are not damaged can be reassembled to continue to use, if you often meet the phenomenon of the wheel is entangled in the debris suggested that the assembly of anti-entanglement cover to avoid.
2, universal wheel casters loose or wheel jamming can also cause "grinding point". Appropriate maintenance checks, especially check the tightness of the bolt, the amount of lubricant, replace the broken casters can enhance the rolling performance of the equipment and rotational flexibility.
3, rubber tires are seriously damaged or become slack may lead to rolling instability, air leakage, load abnormalities, and base plate damage, etc., the timely replacement of damaged tires and bearings can reduce the cost of downtime due to damage to the casters brought about by the loss of costs.
4, after checking and repairing the wheel, to determine whether the bolts and nuts are tightened, as far as possible, in all the bolts on the use of anti-loosening washers or anti-loosening nuts. If the bolts are loose, tighten them immediately. If the wheel mounted inside the bracket is loose it will cause the wheel to be damaged or not be able to turn.
