  1、 Overall transmission structure design 1. Transmission series and principle This model of reducer adopts a two-stage worm gear transmission structure, which achieves a large transmission ratio output of 1:400 through the meshing transmission between the two-stage worm gear and the worm wheel. The first stage is high-speed transmission, with the worm connected to the motor output shaft, res

  What impact does temperature change have on the tr

  26-02-05

  The influence of temperature changes on the transmission efficiency of ZQD750-121-4 gear reducer is mainly reflected through three core paths: changes in lubricating oil performance, thermal deformation of components, and changes in friction pair state. The specific effects and rules are as follows: 1. Negative effects of low temperature environment (ambient temperature<-10 ℃, oil temperature n

  How to choose the current and voltage when welding

  26-02-04

  The NGWD42-16-2.2 planetary gearbox base needs to bear the torque reaction force during operation, and it is required to have sufficient rigidity and crack resistance after welding. Its cast iron material is mostly gray cast iron (HT200/HT250) or ductile iron (mainstream compatible model material). The core principle of welding is to control heat input and reduce stress cracks. The selection of cu

  26-02-03

  The center distance deviation (including positive and negative deviations) of ZLY200-9-1 reducer gears can directly damage the normal meshing state of the gears and cause a series of transmission failures. The specific problems are as follows: 1. Serious and poor gear contact spots Positive deviation of center distance (actual distance greater than design value): When the gears mesh, the bac

  26-02-03

  The reasons for poor contact of gears in ZLY250-21.73-II reducer can be summarized into four categories: substandard manufacturing accuracy of components, assembly process deviation, improper lubrication and maintenance, and problems with working conditions and installation foundations, as follows: 1. Precision defects in component manufacturing Gear machining errors: Accumulated errors in t

  26-02-02

  CWU225-2F is a circular arc cylindrical worm gear reducer, with a housing mostly made of gray cast iron material. Cracks are often caused by overload impact, improper installation, casting defects, or long-term vibration. Inspection requires a comprehensive judgment from three dimensions: static inspection during shutdown, dynamic investigation during operation, and depth inspection during disasse

  26-01-30

  The quality level of lubricating oil has no direct impact on the theoretical output speed of S67-16.86-3KW reducer, but it has an indirect and significant impact on the effective output speed and speed stability in actual operation. The overall degree of impact needs to be judged based on the matching degree of quality level and the performance of the oil. If the matching rules are selected, the i
