The model "TJQ9-B7" should be "TJQ9" (compatible with B7 reducer, output shaft diameter 110 mm). Core parameters (TJQ9) Compatible reducer: B7 Output shaft diameter: 110 mm Input interface: 650 × 590 × 520, bolt 12-M22 (22 × 12) Output interface: 560 × 650 × 700, bolt 12-M27 (28 × 10) Installation related: H ≈ 955, H1 ≈ 210, H2 ≈ 420; Keyway 160 × 200, key 12 × 100 (common) Sele
When selecting the appropriate number of gearbox stages for a specific application scenario, it is important to evaluate the following load characteristics: 1、 Load type and impact characteristics Constant load Uniform loads such as fans, water pumps, etc. can be met by single-stage reducers with high transmission efficiency (95% -98%) Attention should be paid to controlling the load rat
The optimization of the operating state of gear reducers is the core means to improve their efficiency, extend their lifespan, and reduce the risk of failure. It requires systematic measures from five dimensions: design matching, lubrication management, structural improvement, operation monitoring, and maintenance. Specific measures can be broken down as follows: 1、 Optimizing design and selectio
To determine whether the alignment of a multi-stage reducer is good, the core is to detect the relative positional deviation (including parallelism and coaxiality) of the input shaft, intermediate shafts, and output shaft axes, as well as the alignment between the shaft and the coupling (or motor shaft) - poor alignment can lead to gear misalignment, bearing overheating, abnormal vibration, and lo
Compared to standard reducers, non-standard reducers can enhance low-temperature adaptability through targeted design, optimizing operational performance from the source: Material customization: The shell is made of "low-temperature toughness materials" (such as Q345D low-alloy high-strength steel, with an impact toughness of -40 ℃ ≥ 34J, which is better than the 18J of ordinary Q235 steel) to

CJY250-5.2-22KW Shaft mounted Reducer Maintenance Guide 1. Daily inspection and operation monitoring Lubrication status: Check the oil level daily (at the centerline of the oil gauge window) to ensure that ISO VG 220-320 extreme pressure gear oil is used and the oil temperature is ≤ 85 ℃. Vibration and noise: The vibration value during operation should be ≤ 4.5mm/s (RMS value), and abnormal
The bearing replacement of CJY400-66-37 shaft mounted reducer (37kW high-power model, with high load and speed) needs to be comprehensively judged based on the operating status, detection data, and wear degree. When the following situations occur, it must be replaced in a timely manner to avoid the locking damage of core components such as gears and shaft systems caused by bearing failure: 1、 Jud
