How to distinguish the quality of trolley wire?

Sliding line quality:

The quality of the trolley line directly affects the service life of the trolley line. Therefore, we must learn to distinguish the quality of the trolley line when using and purchasing the trolley line. The following is a specific method of differentiation introduced by our Shanghai security trolley line manufacturer. Hope to be helpful to everyone.

Sliding line quality distinction:

1, the overall design. This item does not seem to play much of a role. In fact, it also occupies a certain share. The overall design of the trolley line is in line with most engineering environments. Moreover, the exterior design is conducive to the protection of the trolley line, and it also highlights the aesthetic point of view. This will increase the competitiveness of the product in the trolley market.

2, conductor cross-sectional area, conductor thickness. It is clear that the larger the cross-sectional area of ​​the conductor is, the better is its heat dissipation; the thicker the conductor is, the stronger its conductivity is. When buying a trolley line, it is necessary to observe the cross-sectional area of ​​the trolley conductor, and also to observe the thickness of the conductor. Do not rule out that some manufacturers will pretend that the slip line with a small current flows into a slip line with a large current.

3, conductor aluminum alloy material quality and source. This factor is also the main factor determining the price of the trolley line. Aluminum alloy conductor materials are better and prices are higher, and vice versa.

Only by improving the quality of the safety trolley line can the trolley line be established in the market. Therefore, both the manufacturer and the purchaser must learn to identify the quality of the trolley line and let the trolley line serve us better.

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.
