Damage of universal joint of Xuzhou INA bearing is a common problem in rotary tiller operation. In most cases, bearing fatigue damage will lead to bearing fatigue damage. Generally speaking, only one third of the damage caused by bearing fatigue damage comes from poor lubrication, and one third comes from the incorrect entry of pollutants into the bearing or the improper installation and treatment. However, these types of damages are precise * compact parts unrelated to industrial bearings, so be careful when using high-performance bearings, even if used improperly, can not achieve the desired performance results, and easy to cause bearing damage. According to the investigation, the main reas*** for the damage of the universal joints of rotary tillers are: improper use, incorrect installation, improper selection of universal joints axles and sleeves, failure to maintain in time according to regulati***, turning the knife head or not rising while waiting for lifting and forced rotation.
Measures to prevent damage of cardan joint of Xuzhou INA bearing rotary tiller are as follows:
Rotary tillers should not be used on stony land. The rest of the farm tools should be used.
Firstly, the power combination is adopted, then the farm tools are slowly lowered, so that the blades of the rotary tiller fall into the soil slowly in advance.
The square axis and sleeve length of universal joint should be matched with the type of farm tools. If it is too long, tran***ission parts will be damaged in use. If it is too short, the farm tools will come out when they are lifted.
When the universal joint is installed, the opening of the dialing fork should be on the same * plane to ensure that the rotation force of the Xuzhou INA bearing of the cutter shaft is uniform, otherwise the tran***ission parts will be easily damaged.
Lubrication maintenance should be carried out on time as required. In order to prevent early damage caused by dry friction, oil injection and grease injection should not be omitted at all lubrication points.
The lifting height of farm tools is controlled by hydraulic pressure, and the lifting height of rotary tiller is not more than 20.
When turning, the INA bearing in Xuzhou must be lifted first, otherwise the tran***ission parts will be damaged easily.
In the work, the angle between the universal joint square shaft and the tran***ission plane should not exceed 10 degrees, otherwise the tran***ission efficiency will be reduced. The angle of farm tools should not exceed 30 degrees after hoisting, otherwise the universal joint will be easily damaged. Bearing has the advantages of high rated load, low noise, greatly reducing maintenance costs and prolonging machine operation time. When recognizing the authenticity of bearings, it is faster and more accurate to recognize the authenticity of bearings by touching the steel stamps on bearings. This stamp has no contact if it is touched by hand, but it can be felt by touching Xuzhou INA bearing gently with a nail.
