Battery maintenance and use should pay attention to what

Ensure that the battery is firmly fastened; keep the battery surface clean; ensure that the battery electrolyte level is normal.

(1) Ensure that the battery is fastened firmly The battery should be placed firmly on the vehicle to prevent the battery from disconnecting due to vibration during running, resulting in interruption of power supply.

(2) To keep the surface of the battery clean, dust, dirt, etc. on the battery cover should be cleaned regularly to avoid plugging of the vent hole in the fill hole cover or plug. If solid oxides are found on the poles, they should be flushed with hot water in time to remove them so as not to affect the continuity between the poles and the terminals. After cleaning, clean the surface of the battery and apply grease to the poles and terminals to ensure that the poles are not oxidized.

(3) Checking the height of the electrolyte level of the battery During the charge and discharge of the battery, the water in the electrolyte gradually decreases due to the electrolysis and evaporation, resulting in a drop in the electrolyte level. If it is not added in time, it will shorten the service life of the battery. When the owner finds the liquid level is too low, he should add distilled water in time.

(4) Recharging the battery in time The battery should be recharged immediately after it is discharged or before it is stopped, so as not to cause plate hardening and shorten the service life of the battery.

The Thrust Roller Bearing is used to bear axial and radial joint loads as the main axial load, but the radial load should not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has a lower friction factor, higher speed and a heart regulating performance.

The rod of the 29000 type bearing is an asymmetrical spherical roller, which can reduce the relative slipping of roller and raceway in operation, and has many advantages such as long roller diameter, large diameter, large number of rollers and high load capacity. Usually, oil lubrication is used, and grease can be lubricated at some low speed. In the design and selection, it should be selected first.
The 80000 type thrust Cylindrical Roller Bearing, the 90000 type thrust cone Roller Bearing and the AXK type thrust roller Needle Bearing can withstand the uniaxial axial load, which is much larger than the thrust ball bearing's axial load capacity, and has large rigidity and occupies small axial space.
Thrust cylindrical roller bearing and thrust cone roller bearing are suitable for low rotational speed, and thrust cone roller bearing speed is slightly higher than that of thrust cylindrical roller bearing. The thrust cylindrical roller bearing is a separable bearing. It can only withstand one-way axial load and slight impact, and can restrict the axial displacement of the shaft (or shell) in one direction, so it can be used for unidirectional axial positioning. But its bearing capacity is far greater than that of the thrust ball bearing. When roller is rolling, the roller will inevitably slide on the raceway because of the different speed of the two ends of the roller. Therefore, the limit speed of this kind of bearing is lower than that of the thrust ball bearing, which is usually suitable for low speed operation.
The standard design of thrust cylindrical roller bearing adopts a metal solid cage. According to the requirements of the user, other types or materials can be used. The thrust Tapered Roller Bearing can only bear one direction axial load, which can limit the unidirectional axial displacement of the bearing, so it can be used as a one-way axial orientation. Compared with the thrust cylindrical roller bearing, the bearing capacity is large and the relative sliding is small, but the limit speed is low.
