RX97-2.64-22KW-M1 emergency treatment steps for reducer grease failure, core principles: first stop the machine to stop damage and prevent the fault from expanding, then perform emergency measures to ensure temporary operation, and finally make thorough rectifications to prevent recurrence, adapting to on-site sudden lubrication failure handling. 1. Immediately stop the machine and stop the loss (the first step is to prevent core components from being scrapped) 1. Emergency shutdown and power outage, hang 'No closing' Warning sign to prevent mis-starting; if accompanied by abnormal noise, high temperature, or stuck, forced start and stop is strictly prohibited to avoid broken gear teeth and bearing sintering. 2. Let it cool down until the temperature of the reducer shell drops below 40°C (to prevent hot oil burns and oil splashing) before carrying out subsequent operations. High temperature conditions Disassembly is strictly prohibited 3. Preliminary inspection of failure symptoms: observe whether there is oil or grease leakage, whether there are cracks in the casing, whether the feet are loose, listen to see if the cranking is stuck after stopping, record the fault phenomenon (abnormal noise, temperature, vibration) to provide a basis for subsequent processing 2.

The core of selecting reducer lubricating oil is to determine the ISO VG viscosity grade according to the ambient temperature and operating temperature rise, match the oil type and additives, and follow the manufacturer's manual; low temperature gives priority to fluidity and low pour point, high temperature gives priority to oil film stability and oxidation resistance, and heavy load/impact requires an extreme pressure (EP) formula. 1. Temperature range and viscosity matching (ISO VG, mainly industrial gear oil) 2. Oil type and additive selection Normal working conditions (indoor, medium load, 10℃~40℃): Priority is given to CLP/LCKD extreme pressure industrial gear oil, mineral oil is sufficient, and it is cost-effective. Low temperature/large temperature difference (≤-10℃ or significant temperature difference between winter and summer): Choose PAO/ester synthetic gear oil with high viscosity index, low pour point, smooth start and stop, and stable oil film. High temperature/long-term continuous operation (≥40℃ or box temperature rise ≥80℃): Use high-temperature anti-oxidation and anti-coke synthetic oil or high-grade mineral oil to inhibit oxygen Read More

The wear of the output shaft will cause the noise of the BWD09-87-0.37KW cycloidal pinwheel reducer to become louder, and this is usually one of the common causes of abnormal noise. This is especially true when the journal, keyway, spline or mating surface with the bearing/coupling is worn. 1. The mechanism and performance of wear and noise caused by increased fit clearance: journal wear causes the fit between the inner ring of the bearing and the shaft to loosen, causing radial runout, impact and abnormal noise during operation; keyway/spline wear causes the coupling/sprocket to loosen, causing periodic impact sounds or slipping noises. Coaxiality and force imbalance: shaft bending or uneven wear destroys the meshing and support accuracy, and the cycloidal wheel and pin teeth are not meshed well, resulting in high-frequency whistling or knocking sounds; at the same time, bearing wear is aggravated, forming a vicious cycle. Typical noise: It is mostly a 'clang' impact sound at low speed, and it is a sharp whistling or irregular buzzing sound at high speed, often accompanied by increased vibration and abnormal temperature rise. 2. Investigation and treatment suggestions (1) Stop Read More

The power input end of the B13-43-5.5KW cycloidal pinwheel reducer is usually equipped with a three-phase asynchronous motor (5.5KW is commonly used for 380V three-phase electricity, and a few are customized for 220V single-phase, which must be subject to the motor nameplate). The power connection must comply with electrical safety regulations and motor wiring requirements. The specific steps are as follows: 1. Preparation before connection 1. Confirm that the parameters match and check the motor nameplate: focus on confirming the rated voltage (such as 380V/50Hz), rated current, and wiring method (△-shaped or Y-shaped). 5.5KW motors mostly have △-shaped wiring, which must be consistent with the power supply voltage. Check the power supply line: it needs to be equipped with a circuit breaker that matches the motor (16–20A recommended), a thermal overload relay (the setting current is set at 1.1 times the rated current of the motor), and a contactor. The line path should be no less than 2.5mm² copper core wire to ensure load-bearing capacity. 2. Tools and materials Preparation tools: Read More

BLD10-17-0.75KW Fixing steps after leveling the base of the cycloidal pinwheel reducer BLD10 is a horizontal cycloidal pinwheel reducer (B stands for cycloidal pinwheel, L stands for vertical installation and is derived from horizontal type, D stands for motor direct connection, 10 is the frame number), 0.75KW The power model has a smaller load. The core of fixing is to ensure that the anchor bolts are evenly stressed, that the machine base has no stress deformation, and that anti-loosening measures are in place. The specific operations are as follows: 1. Confirm the leveling status and clean the fitting surface. Before fixing, use a level to re-test the longitudinal and transverse leveling of the machine base to ensure the error is ≤0.05mm/m; clean the oil stains and iron filings between the bottom surface of the reducer base, the installation foundation, and the pads to ensure that there is no gap in the joint surface to avoid warping of the machine base after tightening. 2. Anchor bolt pre-tightening (diagonal tightening method) adopts the principle of diagonal step-by-step tightening, and operates in the order of 'upper left - lower right - upper right - lower left' to avoid unilateral stress.

BWED3322-121-5.5KW is a medium-power two-stage horizontal cycloidal pinwheel reducer. Its internal transmission structure, sealing system, and lubrication cycle are all designed for the specified steering. Motor steering errors will accelerate component deterioration from multiple dimensions and greatly shorten the service life of the reducer. The specific effects are as follows: 1. The core transmission components accelerate wear and failure, and the service life is reduced by 50%. The meshing transmission of the above cycloidal pinwheel reducer relies on the directional surface contact between the cycloidal wheel and the pin teeth. The contact stress is designed to be evenly distributed under steering and the wear rate is controllable. When the steering is wrong, the direction of the meshing force is reversed, the contact area is transferred from the designed load-bearing surface to the non-load-bearing surface, and the local contact stress will exceed the design threshold. 1.2-1.8 times, resulting in pitting and spalling on the cycloidal gear tooth surface in a short period of time, increased wear of the needle roller bearing raceway, and deformation of the cage. For 5.5KW model, wrong steering runs 100-200 小 Read More
