In a worm and worm gear transmission system, simply changing the transmission ratio of the worm and worm gear does not necessarily effectively reduce the wear of the worm gear if it wears out too quickly.
The problem of the relatively fast wear rate of the worm gear can be caused by a variety of complex factors. Unsuitable material selection is one of the common reasons. If the wear resistance of the materials of the worm gear and the worm is poor, it is easy to accelerate the wear during the transmission process. The quality of lubrication conditions is also crucial. Lack of sufficient and good lubrication, or the use of inappropriate lubricating oil and grease, as well as failure to replace and replenish them on time, will increase friction and lead to accelerated wear of the worm gear. In addition, excessive load exceeding the bearing capacity of the worm and worm gear, insufficient installation accuracy resulting in inaccurate matching of the worm and worm gear, and harsh working environment full of dust and impurities, etc., may all be factors causing rapid wear of the worm gear.
The change of the transmission ratio does affect related parameters such as torque and rotational speed, but this change does not necessarily directly reduce the wear. In some cases, if the adjustment of the transmission ratio leads to changes in the load characteristics, such as an increase in the load, it may even aggravate the wear of the worm gear.
To effectively reduce the wear of the worm gear, more targeted and comprehensive measures need to be taken. Firstly, more wear-resistant and suitable materials should be carefully selected to manufacture the worm gear and the worm to fundamentally improve their wear resistance. Secondly, it is necessary to ensure good lubrication effect, select the appropriate lubricating oil or grease, and strictly replace and replenish them regularly in accordance with the regulations. Furthermore, a comprehensive and reasonable assessment and strict control of the load should be carried out to resolutely avoid the transmission system operating under overload. In addition, during the installation process, efforts should be made to improve the accuracy to ensure that the worm and worm gear can be correctly assembled and precisely aligned. Finally, actively improve the working environment to minimize the adverse effects of external factors such as dust and impurities on the transmission system.
