Water cooling: The oil pan of the cycloid reducer is equipped with a curved water pipe. View the popular products of reducer manufacturers: gear reducer. The pipeline is equipped with cooling water, which can eliminate the heat of the air in the oil.
The working temperature of the lubricating oil of the cycloid reducer should generally not exceed 90 degrees Celsius. The serpentine tube is usually made of copper or brass. If the temperature is too high, the Wholesale gear reducers physical and chemical properties of the oil will change. Fan cooling: If the case is not suitable for natural cooling, you can use a fan for cooling.
Common methods for reducing the temperature of the cycloidal pinwheel gear reducer: 1. Natural cooling: If a typical cabinet does not meet your heat dissipation requirements, you can add a radiator outside the cabinet and place it in natural air. 2. 3. For example, reducing the viscosity of the varnish will reduce the load-bearing capacity of the varnish film, which may eventually lead to direct contact between the working tooth surface and the side rubber

When the reducer was disassembled and repaired, it was found that there were many cracks, wear and blockage on the second-stage cycloid pin wheel of the reducer. When repairing welding cracks, the roots must be thoroughly cleaned with a grinder before welding on the back to expose the metallic luster. Because this part requires good wear resistance and high precision, but poor weldability, stainless steel electrodes with good crack resistance, wear resistance and good machinability are selected as filler materials.
The welding machine is AX-320, reverse connection. After welding, the whole part is kept warm and slowly cooled after welding. According to the shape, depth and length of the crack, a grinder is used to eliminate shallow and short cracks first, and then to eliminate long and deep cracks. The repair welding sequence is to weld short and shallow cracks first, then weld through cracks, and finally surfacing the defective Wholesale Cycloidal Gear Reducer parts to the original shape.22mm, it is heated to 350 ℃ and bake for 2h, the welding current is 90-l00A, the welding voltage is 20-22V, and the welding input energy is 8-12kJ/cm.
During the construction of the tower crane, the tower body suddenly failed to rotate. When repairing short and shallow cracks, pay attention to starting the arc from the tail of the crack first to prevent cracks from appearing in the welding process, weld point by point, and observe while welding. Weldability analysis shows that the material of the cycloid pin wheel is GCr15, which has high carbon content, high hardening tendency, cracks and S and P segregation, high thermal cracking sensitivity, and poor weldability. The cycloidal needle wheel can be used for more than 5 years after self-repair.
It has good performance, fully meets the requirements of use, and saves maintenance costs. Because there are no spare parts in stock, it was decided to repair by welding. For uncracked cracks, smooth transition at the bottom of the groove to reduce stress concentration; for cracks with cracks, a single V-shaped groove is opened. The grinding sequence starts from the end of the crack until the crack disappears to prevent the crack from spreading, while grinding the groove. The brand is A307, the specification is ¢3.
After cooling to room temperature, the two planes are processed on the lathe, and the excess surfacing metal on the edge is trimmed with a file until the cycloid pin wheel returns to its original geometric size. Correct the crack to make its surface in a plane, and fix it by spot welding. For worn and defective parts, oil stains and rust should be removed before repair welding. Through the observation of the first crack repair welding, no cracks appeared, and no new cracks appeared, which proved that the welding process was feasible.

The following editor briefly introduces several commonly used Wholesale planetary gear reducers cooling methods for reducers: The first one is to use a cooling fan.
The second type is the cooling coil.There are several cooling methods for industrial gearboxes. The fourth type is to use an external lubricating oil cooling device for cooling. This is easy to understand, is to use a combination of the above two. One thing to say here, there are two lengths of L3, the one we see now is with a fan, the length is longer, and the other is without a fan.
In this case, a cooling coil is placed in the gear box, and water is fed in while water is discharged at the same time. When the gearbox is in operation, use an oil pump to pump out the oil inside the gearbox for cooling, and at the same time add oil at room temperature to the gearbox, and use lubricating oil for cooling.. The third type is cooling fan + cooling coil.
The temperature of the lubricating oil in the gear box is lowered through the flow method. This method is suitable for equipment with large load and high heat generation. When installing, install a cooling fan at the end of the input shaft and blow it against the housing of the gearbox
