- Comparison of helical planetary reducer and straight planetary reducerThe helical planetary reducer can be regarded as a set of cylindrical gears with misaligned thin gears, so the contact points of each part are located at different parts of the tooth profile, thereby producing the effect of compensating the error of each thin gear.The elasticity of the teeth is very efficient, so a tooth with an error of less than 10 mm can average out, and under load, run as smoothly as a tooth with an error of 1 mm.Since at a given moment approximately half of the time (assuming a certain degree of overlap of 1.5) there will be two teeth, this has an added benefit in terms of strength.Therefore, the stress can be based on 1.5 times the tooth width instead of one tooth width.The main disadvantage of spur planetary gear units is that they generate vibration.Whether due to design, manufacturing, or deformation, some variation in the involute profile may occur simultaneously along the entire tooth flank.This will result in periodic one-shot firing of each tooth, which is usually quite intense.The resulting vibrations cause large loads on the gears and noise

- Basic requirements for gear reducer safety factorOne of the basic requirements for the safety factor of a gear reducer is to make the gears have sufficient load-bearing capacity.Recently, although there are recognized (standard) calculation methods for the load-carrying capacity of the tooth surface, tooth root and gluing, there are many factors (commonly used coefficients or parameters) that affect the load-carrying capacity of gears, and some influencing factors are contradictory and mutually inconsistent. Therefore, for a general engineer who is initially involved in gear design, it may be difficult to complete the gear transmission design satisfactorily.newgear clearly pointed out in IS06336: 1996 the calculation method of the bearing capacity of involute cylindrical spur gears and helical gears: ISO6336 is not used to guarantee the performance of the installed gear device, nor can it be used by general engineers. provided by experienced gear designers.These designers can reasonably choose the values of the coefficients in the formula based on similar design experience, and have a clear understanding of
- The principle and maintenance method of the reducerThe working principle of the reducer and the working principle of using the planetary reducer in life: The reducer is a device that transmits power and movement. The main function is to reduce speed and increase torque. The key application method is also the conversion of speed and torque. Pathways include power transmission events, load adjustments, and precise angle transmissions.The principle of the reducer is to inject new oil of the same brand.The principle of the reducer is to check the viscosity index of the oil. If the oil is obviously dirty, it is recommended to replace it as soon as possible.There are many ways for the reducer to achieve the purpose of deceleration, and the most common one is to use the speed conversion effect of the gear to achieve the deceleration. The advantages of using the gear are that the structure of the reducer can be compact, the volume is reduced, and it can have a high efficiency. Economical, this is why many people call the reducer a gearbox.Remove all oil.The position of the oil level plug, oil drain plug and breather is determined by the installation position.Since the reducer is only a power transmission mechanism, it does not have the driving ability itself
- Correct installation steps of planetary gear reducerThe correct installation, use and maintenance of the reducer is an important link to ensure the normal operation of mechanical equipment.Therefore, when installing the planetary reducer, please be sure to assemble and use it in strict accordance with the following installation and use related matters.The first step is to confirm whether the motor and reducer are intact before installation, and strictly check whether the dimensions of the parts connected to the motor and reducer match. Here are the dimensions and fit tolerances of the positioning boss of the motor, the input shaft and the groove of the reducer .The second step is to unscrew the screw on the dust-proof hole outside the flange of the reducer, adjust the PCS system clamping ring to align the side hole with the dust-proof hole, insert the inner hexagon and tighten.After that, remove the motor shaft key.The third step is to naturally connect the motor with the reducer.When connecting, it must be ensured that the concentricity of the output shaft of the reducer is consistent with that of the input shaft of the motor, and that the outer flanges of the two are parallel.If the concentricity is inconsistent, it will cause the motor shaft to break or the reducer
