<h2>Product Description</h2>
Joint bearing: It is a spherical sliding bearing, which is composed of inner and outer rings with spherical sliding spherical contact surfaces. Joint bearings are mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, which can withstand large loads. According to its different types and structures, it can withstand radial loads, axial loads, or combined loads that exist both radially and axially. Due to the composite material embedded on the outer spherical surface of the inner ring, this bearing can generate self-lubricating during operation. It is generally used for swinging movements with lower speeds, and can also be tilted within a certain angle range. When the support shaft and the shaft shell hole are not concentric, it can still work normally. Self lubricating joint support is applied in industries such as water conservancy and professional machinery. Due to the large spherical sliding contact area and inclination angle of joint bearings, as well as the fact that most joint bearings adopt special processing methods such as surface phosphating, galvanizing, chrome plating, or external sliding surface lining, pad insertion, spraying, etc. Therefore, it has a large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self centering, good lubrication or self-lubricating without lubricating dirt pollution. Even if installed incorrectly, it can work normally. Therefore, joint bearings are widely used for lower speed swing, tilt, and rotation movements.
Universal joint: By utilizing the characteristics of its mechanism, the two shafts can rotate continuously and reliably transmit torque and motion when they are not on the same axis and there is an angle between the axes. The biggest feature of a universal joint is that its structure has a large angular compensation ability, a compact structure, and high transmission efficiency. The angle between the two axes of different structural types of universal couplings is not the same, generally between 5 ° -45 °.
The cross shaft universal joint is a widely used universal joint, and the bearing is a vulnerable part of the cross shaft universal joint. The main difference between several large cross shaft universal couplings lies in the changes in the bearing seat and cross head, forming different structural forms. To ensure the synchronization of the main and driven shafts, a double connection form is adopted in practical applications. The double connection method is nothing more than welding or flange plate connection through bolts, and there can be various forms of changes in the length of the middle. Both heavy-duty and small-sized cross shaft universal couplings are universal types, and different models in the automotive industry have their own dedicated cross shaft universal couplings or other types of universal couplings. In addition, agricultural machinery, industrial machinery and other sports machinery products also have dedicated universal couplings, and most of them use cross shaft universal couplings.
