The tire changer is one of the devices included in the equipment of car workshops and vulcanization. It is used to take off and put (mount) car tires on rims. We distinguish between semi-automatic and automatic tire changers.
Tire changers can be equipped with a number of additional elements, for example:
• Leverless attachment (eliminates the need to use an assembly spoon) ,
• adapter for Run-Flat tires.
Balancing machine - a device for balancing rotating machine elements such as rotors, shafts, car and motorcycle wheels.
In the wheel balancer for car and motorcycle wheels, balancing the weight distribution of the wheel with respect to its axis of rotation is achieved by means of balancing weights. The weights are placed on the circumference of the rim at points indicated by the machine as places to be loaded to obtain the correct weight distribution in the wheel. Unbalanced or unbalanced wheels cause vibrations while driving, which translate into unpleasant vibrations of the steering wheel and stress on the suspension components.
Currently used balancers have a balancing accuracy of up to 1 gram, and the differences in individual devices come down to the degree of automation of the activities performed and the precision of indicating the place where the weight is to be attached.
There are also balancers for balancing drive shafts.
The following issues are related to balancing rotating machine parts:
• static balancing - allows to detect the position of the center of mass outside the axis of rotation, but not to determine the asymmetry along the axis of rotation. Can be carried out without setting the wheels in motion,
• dynamic balancing - allows you to correct the position of the mass along the axis. It is performed by analyzing the moments of forces generated by a rotating wheel.
