The hard tooth surface gear reducer must be located under the flat propulsion base, and the anchor bolts must be driven and frozen.TRANSMISSION - HARDENED SURFACE REDUCER - Each connecting shaft of the working machine, machine equipment must be precisely directed to the main working limit of the center line shaft end and the output end of the reducer manufactured according to h6.The internal threads of transmission components, such as couplings, pulleys and sprocket chains, must be manufactured in accordance with the corresponding public service restrictions to avoid installation.Too tight will destroy the rolling bearings, too loose a fit will jeopardize all normal drive transmission.When the transmission parts such as sprocket chain and transmission gear are installed on the shaft, the rolling bearings should be as close as possible to reduce the bending stress of the shaft.When installing the motor on the hardened gear reducer, unsalted butter should be modified on the hole wall and keyway at the top of the worm to avoid over-tight installation and long-term rusting of the hole shaft.When ordering various hard tooth surface reducers, if the electric Read More

Cylindrical gear reducer is one of many reducers.For it, we must first analyze its structure.We may not yet know that its structural features can be divided into several levels.Let's take a look at it in detail.(1) According to the structural characteristics, it is divided into 1-stage reducer, 2-stage reducer, 3-stage reducer and multi-stage gear reducer.(2) The cylindrical gear reducer is mainly composed of parallel shaft gears, cylindrical gears, sealing rings, transmission shafts and boxes.(3) The first-stage transmission ratio is generally 8-10, mainly to avoid excessive contour.If I is required to be greater than 10 (I represents the transmission ratio), a two-stage cylindrical gear reducer is used.(4) The 2-stage gear reducer is suitable for the case where the transmission ratio is 8-50, and the total intermediate distance between the high and low speed stages is 250-400mm (5) The 3-stage is used for the use requirements that require larger transmission.cylinder Read More

Hard tooth surface reducers are widely used in industrial and large-scale transmission-related equipment, and parts that have not been inspected, accepted by the technical and inspection department, unprinted and wet-painted are prohibited from being equipped.The assembly, partial assembly and final assembly of the hardened gear reducer must be carried out in accordance with the equipped process sequence without process intervention.The parts of the hard tooth surface reducer should be cleaned before being equipped. The rolling bearings should be cleaned with gasoline or high-quality cleaning agent, and then dried with compressed air.When equipped, each mating surface shall not be corrected when equipped.Matching parts are required, except for repairing keys and keyways.Before the rolling bearing is installed on the shaft, the paint should be preheated and the thermal expansion should be calculated.The hard tooth surface reducer should be debugged after being equipped, and the debugging speed should be close to the rated working speed of the reducer.It is strictly forbidden to add abrasives and impurities to the lubricating oil during debugging, and the contact ratio of the tooth surface should meet the requirements.After passing the hard tooth surface reducer, the skill assessment part will be printed and identified.

Oil leakage of cycloid reducer is one of the common faults of cycloid reducer, and it is a headache. How to effectively control oil leakage is of concern to people.Whether the oil return of the cycloid reducer is smooth is also an important factor for the oil leakage of the cycloid reducer.The smooth flow of oil return is to make the oil that may leak outside flow back into the tank relatively smoothly.For example, the oil splashed on the inner wall of the box needs to be made to flow back to the oil pool in the box as soon as possible, so the inner wall of the cycloid reducer box cover is made into an arc shape, in order to prevent the oil from staying at the shaft head sealing device , in order to prevent the oil from gradually leaking out of the box along the shaft head, the oil groove type sealing device is adopted at the shaft head, and there is an oil return essence at the lower end of the oil groove, so that the oil accumulated in the oil groove can flow back into the box to prevent leakage.The oil return tank with a rectangular section on the seat surface of the cycloidal pinwheel reducer box can make the oil splashed on the inner wall of the box cover drip along the inner wall, collect into the oil return tank, and then flow back to the oil pool.The size of the reflux tank is large Read More

Everyone is quite familiar with the servo planetary reducer. Many users do not know the operation process when using the reducer, which leads to failure. Today, the servo planetary reducer manufacturer will give you a brief introduction based on years of experience: the servo planetary reducer is installed. In principle, the model of the reducer bracket is determined according to the size of the output shaft diameter of the servo planetary reducer. As long as the interface form and size match, the size of the output shaft of the servo planetary reducer can be adjusted up and down within a certain range for the model of the servo planetary reducer bracket. branch.If the servo planetary reducer bracket with connection plate is selected, if the installation size of the servo planetary reducer does not match the reducer bracket, within a certain range, our company can adjust the connection between the speed connection plate and the servo planetary reducer to meet user requirements.Bapman introduced the operating procedures of the servo planetary reducer: 1. Inspection before starting ①, the reliability of the fastening of each fastener; ②, whether the oil level of the lubricating oil meets the requirements; ③, whether the wiring of the oil supply pump is correct; Read More

(1) Choice of vibration measurement method: There are two measurement methods for the vibration of the planetary reducer gear unit, one is to measure the vibration of the box and the other is to measure the vibration of the shaft.It is also often more effective to combine these two measurement methods to obtain the absolute movement of the shaft in the gear unit.For planetary reducer gear units supported by rolling bearings, the radial clearance of the bearings is small, and the relative movement between the bearings and the box is also small, so the vibration measurement of the box should be used.For gear units supported by ordinary sliding bearings, shaft vibration measurement or box vibration measurement can be used.However, when the frequency is in the range of 0-500Hz, it is not easy to measure small vibrations due to the insensitivity of the box vibration measurement, and the shaft vibration measurement should be used.The vibration measurement of the box can obtain a wide frequency range and its dynamic characteristics, which can provide the necessary basis for the analysis of the meshing frequency of the gear teeth.(2) Shaft vibration measurement: http://www Read More
