ZL42.5-2 belongs to the ZL series two-stage cylindrical gear reducer (center distance 425mm, nominal transmission ratio 2). According to JB/T 8853-2015 standard, it has a total of 5 assembly forms (Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ). The core difference lies in the input/ The position, rotation and installation orientation of the output shaft are as follows: 1. Assembly form I input shaft and output shaft are in the same direction (both on the same side of the reducer box), with the input shaft at the top and the output shaft at the bottom; installation method: horizontal foot installation (fixed base), the input shaft can be clockwise/counterclockwise (according to motor rotation); applicable scenarios: equipment with compact space and input and output that need to be arranged on the same side (such as small conveyors and mixers). 2. Assembly form Ⅱ input shaft and output shaft are reversed (separated on both sides of the box), the input shaft is on top, and the output shaft is on the bottom; installation method: horizontal foot installation, input shaft and output shaft rotate in opposite directions; applicable field Read More

The working environment temperature of the ZL35-12-I gear reducer mainly changes the effective output power of the motor indirectly or directly by affecting the motor heat dissipation efficiency and the performance of the reducer lubricating oil. The specific effects are as follows: 1. The impact of high temperature environment (ambient temperature > 45°C) on motor power 1. The heat dissipation efficiency of the motor decreases and the effective power attenuates. The rated power of the motor is based on the standard ambient temperature (25°C) Calibrated, when the ambient temperature exceeds 45°C, the temperature difference between the motor shell and the environment decreases, the heat dissipation speed slows down, and the winding temperature rises rapidly. In order to prevent the winding insulation layer from aging due to high temperature, the allowable output power of the motor will be forced to be reduced. (1) Empirical rule: for every 10°C increase in ambient temperature, the effective output power of the motor will decrease by 8% to 12%; when the temperature reaches 60°C, the power attenuation can reach 20% to 30%. (2) Impact on ZL35-12-Ⅰ Read More

Adjust BLEY3922-5133-0.55kW The meshing gap between the cycloid wheel and the pin gear shell of the cycloidal pin wheel reducer is a key operation to ensure smooth transmission, reduce noise, and extend the service life. The standard range of the meshing gap of this model is 0.15~0.30mm. The specific adjustment steps are as follows: 1. Gap measurement and marking before disassembly. First, manually rotate the input shaft, feel the rotation resistance and record the abnormal position; then use a feeler gauge to measure the gap between the cycloidal wheel tooth top and the pin tooth pin, and mark the area where the gap is too large or too small to provide reference for subsequent adjustments. If the reducer has a double cycloid structure, alignment marks must be made on the two cycloid wheels, eccentric sleeve, and output flange to avoid assembly phase errors after disassembly and affecting the gap adjustment accuracy. 2. Disassemble the core components and clean and inspect them. Remove the motor, input shaft end cover, output flange, pin bushing and pins in sequence, and take out the two cycloid wheels. Please note that it is forbidden to knock the cycloidal wheel and pin teeth during disassembly. Read More

The core of controlling the start, stop and operating load of the motor supporting the BLEY4527-595-4kW cycloidal pinwheel reducer is to match the motor characteristics and the working condition requirements of the reducer to avoid start-stop impact damage to transmission components and overload operation to shorten the life of the equipment. Specifically, precise control can be achieved through the three dimensions of electrical control, mechanical protection, and working condition optimization. The operation method is as follows: 1. Smooth control of motor start and stop (reduce impact load). The reducer has a reduction ratio of 595. It is a large reduction ratio and low-speed model. The instantaneous impact when the motor starts and stops will be amplified, which can easily cause the cycloid wheel and pin tooth pin to break. The following electrical and operating methods need to be used to buffer the impact: 1. Electrical control scheme (preferred) (1) Install a frequency converter for speed control starting with a matching 4kW motor. Use a general-purpose frequency converter (adaptive motor power ≥5.5kW to avoid overload), and set a soft start/ Soft stop parameters: Set the start time to 5~10s and stop Read More

The core technical parameters of RF87-NA45-Y112-D340 reducer are as follows: 1. Model meaning Disassembly of RF87: R series helical gear hard tooth surface reducer, F = flange installation, 87 = frame size (medium size) NA45: hollow shaft output, shaft diameter φ45mm (with locking disc/expansion sleeve) Y112: adapted to IEC standard Y series motor, frame size 112 (common 4 pole, power about 4kW) D340: center distance/installation distance 340mm (or flange installation size code) 2.

RF67-11.54-2.2kW reducer belongs to R series hard tooth surface helical gear reducer, frame number 67, reduction ratio 11.54, adaptable to 2.2kW The motor, with its characteristics of small size, medium torque and impact resistance, is highly consistent with the working conditions of small and medium-sized auxiliary equipment in mining machinery. The specific adapting working conditions are as follows: 1. The power transmission of small mining conveying equipment is suitable for small belt conveyors, scraper conveyors, screw feeders and other equipment underground or on the ground, such as scattered material transfer in mine tunnels, quantitative feeding of powder in mineral processing plants, and material transportation at the discharge port of silos. The reduction ratio of 11.54 can convert the motor's high speed into medium and low speed output (when the input is 1450r/min, the output speed is about 125.6r/min). The 2.2kW power is enough to drive a small conveying mechanism. The hard tooth surface gear can cope with the slight impact load when conveying materials such as ore and coal powder. Read More
