The composition and characteristics of worm gear reducers, including locking characteristics, are analyzed and explained in a small series. In fact, for many large equipment, planetary gear reducers are often used.If there is a worm in the reducer, there will be a worm gear, so the worm reducer is just a common name for the worm reducer.However, generally speaking, we prefer to refer to the worm gear reducer as the worm gear reducer. The following is a brief introduction to some characteristics of the worm gear reducer: In order to obtain a larger transmission ratio, the closely connected tooth flanks of the two wheels are in overlapping contact with respect to the helical gear arrangement of the staggered axes, so that the load can exceed the helical gear arrangement of the staggered axes. The worm transmission of the worm gear reducer is a simple screw transmission, which is a multi-tooth meshing transmission, so the transmission is stable, the noise is relatively small, and it has self-locking ability.When the lead angle of the worm is less than the equivalent between the meshing teeth and conflict occurs, this arrangement also has self-locking capability, which can complete reverse self-locking, and the worm wheel can only be driven by the worm, not through the worm wheel.Just like the self-locking worm gear used in heavy machinery, its reverse self-locking ability can complete the effectiveness of maintenance. When the transmission efficiency of the worm gear reducer is low, the friction is serious.During the transmission process, the worm gear slides relatively fast, so the loss is relatively large and the energy efficiency is relatively weak. In addition, relatively high sliding speeds lead to severe tooth flank friction and constant heating.In order to prevent heat generation and reduce losses caused by friction, materials with higher prices, better anti-friction performance, better anti-friction ability and materials with lubricating advantages are often selected, but the cost is higher. The characteristics and locking analysis of the worm gear reducer are roughly as above.For the reducer, we also need to understand its characteristics before we can start using it.
