The spline shaft is a kind of mechanical transmission. The flat key, half-circle key, and oblique key have the same function to transmit mechanical torque. There is a longitudinal keyway on the surface of the shaft, and the rotating part sleeved on the shaft also has a corresponding keyway, which can be retained. Rotate synchronously with the axis. While rotating, some can also slide longitudinally on the shaft, such as gearbox shift gears.

The stainless steel roller conveyor has a large conveying capacity; the traction chain has high strength and can be used for long-distance conveying; and the layout of the transmission line is flexible. Compared with the mesh belt conveyor, the stainless steel roller conveyor can convey under a larger skew angle and a smaller bending radius, so the flexibility of placement is greater. The angle of the stainless steel roller conveyor can reach 30°-35°, and the bending radius is generally about 5-8m; various processings such as sorting, drying, cooling or assembling can be carried out during the conveying process. The operation is stable and reliable; the structure of the stainless steel roller conveyor is varied. Stainless steel roller conveyors are generally classified as follows: according to the device form of the roller conveyor, it can be divided into fixed and mobile; according to the layout of the roller conveyor, it can be divided into horizontal, horizontal, skewed, horizontal skewed, etc. The material conveyed by the roller conveyor is in a closed state from the inlet to the outlet, and the outlet does not need to be equipped with a dust collector, which can ensure that no dust leaks into the environment during the conveying of the material. The material is smoothly conveyed along the roller conveyor, and there is no internal movement at all, so the conveyed material is less damaged, and the slow roller conveying causes very little damage to the conveyed material.

<p>The roller is an important part of the belt conveyor. There are many types and large quantities. It accounts for 35% of the total cost of a belt conveyor and bears more than 70% of the resistance, so the quality of the roller is particularly important. Now the support Roller manufacturers attach great importance to this aspect, and have invested a lot of money and equipment in the roller production line and roller production equipment. The role of the roller is to support the weight of the conveyor belt and the material. The roller must be flexible and reliable in operation. Reduce transportation The friction with the same roller and roller accessories plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. Although the roller is a small part in the belt conveyor, the structure is not complicated , But it is not easy to manufacture high-quality rollers and roller sets.</p>

<p>Construction process of roller encapsulation</p> <p><strong>1. Polishing the roller</strong></p> <p>Clean up the residual glue on the roller, then use a special grinder to polish a rough surface without rust on the roller, and finally use a fiber disc to lightly polish it. </p> <p><strong>2. Clean the noodles</strong></p> <p>Sweep the polished surface clean with a cleaning brush, and then clean it with a non-toxic flame-retardant cleaning agent to ensure that there is no residue on the surface of the roller. If there is water on the surface of the drum, let it dry. </p> <p><strong>3. Apply adhesive</strong></p> <p>First, apply the metal treatment agent thinly and evenly on the polished surface of the roller, and let it dry completely. Then mix the adhesive in a specific proportion evenly, apply forcefully and evenly on the cylinder once, wait for it to dry completely, and then paint a second time, and also paint on the surface of the rubber sheet. </p> <p><strong>4. Paste the rubber sheet</strong></p> <p>When the adhesive dries to slightly sticky but does not adhere to the back of the fingers, paste the rubber sheet, and roll it with a compaction roller, use a rubber hammer to beat the rubber sheet firmly to ensure that there are no bubbles inside, and finally fill it with a glue gun Seams, and polish the edges. </p>
