In the reducer, the planetary gear reducer has the characteristics of light weight, small size, wide range of transmission ratio, high efficiency, stable operation, low noise and strong adaptability, so it is widely used in metallurgy, mining, lifting transportation, electric power , energy, building materials, light industry, transportation and other industrial sectors.However, the planetary reducer must be installed before use.Improper installation may cause the output shaft of the reducer to break, causing unnecessary economic losses to the enterprise.In order to let everyone better understand the installation steps and reduce unnecessary economic losses, today Jiangsu Juzhili will take you to understand the installation steps and precautions of the planetary reducer.1. Installation 1. Step 1: Before installation, confirm whether the motor and reducer are in good condition, and strictly check whether the dimensions of the components connected to the motor and reducer match.The following are the dimensions and fit tolerances of the motor positioning boss, input shaft, and reducer slot.2. Step 2: Unscrew the outer flange of the reducer Read More

The torque of the reducer is the output torque of the motor, which is one of the basic parameters of the motor.The torque of the reducer is inseparable from the motor speed, power and other factors.Today Jiangsu Juzhili will take you to understand the commonly used torque formula and the calculation of servo motor torque.Hope the knowledge we share can help you.1. Formula: T=9550P/n The formula commonly used in engineering: torque; power; calculation formula for the relationship between speed.Among them: t-torque; 9550-constant (no need to investigate its source); p-motor power (kw); n-output speed (rev/min) Note: It should be noted that the gear transmission should be considered when calculating the torque through the reducer factor of efficiency loss.4. The torque calculation formula of the servo motor is: T=F*R*reduction ratio.Example: Driving a 100kg object, R=50mm, reduction ratio: 1: 50, 3. Regarding the reduction ratio: Read More

The entire transmission device of the cycloid reducer can be divided into three parts: input part, deceleration part and output part.Installation steps: 1. Check whether the two cycloidal wheels are a pair. The production of the cycloidal wheel is based on a pair, that is to say, the two pieces of the cycloidal wheel are not separated during the production process.When installing, the concept of a pair is that the two cycloidal wheels can completely overlap.Including the bearing hole, the ten holes (shaft pin hole) and the external tooth shape are safe coincidence at the same time, and it looks like one piece from the front. If they can overlap, it proves to be a pair. If they cannot overlap, it proves that they are not a pair and cannot be used.Note that cycloidal wheels have pros and cons, and there are marks on the cycloidal wheels, and the marks of each pair of cycloidal wheels are also different.2. Rotate one of the cycloid wheels by 180°, that is, when the middle bearing holes are completely overlapped, the outer tooth shape is just misaligned, and the heel position of the upper piece is exactly the tooth top position of the lower piece.Note that the relative positions of these two wheels must be remembered.

How to prevent reducer gear damage?1. Analysis of tooth breakage elements: gear breakage is divided into fatigue breakage and overload breakage.During the working of the gear transmission, the gear teeth are subjected to alternating loads for many times, and the bending fatigue stress acts on the risk section of the tooth root, and fatigue cracks occur at the tooth root. Under the action of the alternating bending fatigue stress, the fatigue cracks gradually Widening, after all, will cause the teeth to bend and break due to fatigue; during the gear transmission, if the gear is subjected to short-term overload, or impact load, or the teeth are severely worn and thinned, overload and breakage will occur. Treatment method: increase the transition circle of the tooth root Corner radius, reducing the value of the surface roughness to be processed as much as possible can reduce the influence of stress convergence, increase the stiffness of the shaft and support, and ease the load on the tooth surface; make the center of the gear tooth have sufficient toughness; Appropriate strengthening treatment at the root can improve the fracture resistance of the gear teeth.2 Analysis of gear pitting and dropout factors: pitting corrosion and dropout on the gear surface Read More

What are the factors that reducer oil temperature is too high?Factor analysis: a. Lubricating oil is unqualified or used for too long.At present, most of the lubricating oil used in our group's reducer is 320# extreme pressure gear oil. If you add expired or inconsistent oil with this type of lubricating oil and the lubricating oil has not been replaced for a long time, the oil temperature of the reducer may be too high; b. Too much lubricating oil.When the height of the oil level is higher than the oil dipstick or the upper and lower limits of the visible hole, the oil temperature of the reducer will be too high; c. The parts are damaged.Damage to mechanical parts includes severe pitting of gears, broken teeth, damage to bearing cages, inner and outer rings, balls, and bearing lockup or serious shaft deformation; d. The outside of the box is covered by debris or dust.When things are piled up around the reducer or the surface of the body has not been cleaned for a long time, the heat dissipation of the reducer may not be complete due to the coverage of debris or dust, resulting in an increase in oil temperature; e. The cooling device is blocked or fails.The cooling equipment is placed in the dusty workshop like the reducer Read More

What should I do if the bearing part of the reducer is overheated and noisy?a. Lack of lubricating oil.When the lubricated oil level is insufficient or cannot reach a reasonable height due to oil leakage from the reducer, it may cause high temperature or noise in the bearing part of the reducer; b. The bearing cover may have some conflicts in the seal.When the bearing is worn due to improper installation, irregular bearing cover or long-term use, the bearing cover or sealing part and the connecting part may cause high temperature or noise in the bearing of the reducer; c. Bearing damage or wear.The main content of this item is that the bearing cage is damaged, the inner and outer rings are worn or deformed, and the balls are worn or dropped out. These factors will make the reducer unable to work normally; d. The bearing gap is too large or too small.The above symptoms may occur when the gap between the ball and the inner and outer rings of the reducer bearing or the gap between the inner ring of the bearing and the shaft and the gap between the bearing and the end cover become larger due to long-term use; e. helical gear The key handle is loose.Looseness of the key handle of the helical gear will cause the gear Read More
