The following by the gear reducer manufacturers interactive multimedia machine to introduce the differences between the two
1、 Basic concept of transmission: gear reducer - the key is to drive the driven transmission gear by the tooth profile of the active transmission gear. Worm gear reducer - it uses the rolling friction caused by the tooth surface when the active worm gear is engaged, and then causes the relative movement of the surface of the worm gear to drive.
2、 Advantages of gear reducer: the gear reducer housing can transmit the driving force of indoor space design three-phase gear reducer motor random bevel gear fitness exercise, that is, the shaft can be parallel, cross or coincidence; the multi-level transmission with smooth rotation and large transmission range is designed, with wide application field, long life and high efficiency (90% ~ 99%), and the housing is dominated by cast iron raw materials The design is beautiful and compact.
3、 Disadvantages of gear reducer: more stringent regulations on transmission gear, cover production line equipment, production, cutting and installation process of transmission gear, resulting in high manufacturing cost. Transmission gear transmission has no over-voltage protection and no self-locking characteristics. Therefore, the brake pedal and brake system machinery and equipment must be upgraded and renovated to have the characteristics of high noise correlation and small single-stage transmission gear transmission ratio (generally no more than 1:7). Liquid grease must be added.
4、 Worm gear reducer advantages: single stage reducer can get a very large transmission ratio (generally 5 ~ 100), compact structure, can add grease or grease use. The disadvantages of worm gear reducer are as follows: the higher the transmission ratio, the lower the efficiency. There are only orthogonal and vertical output methods, limited application site, complicated manufacturing process of raw materials for worm gear copper casting, and the cost of small-scale products. RV worm gear hard journal reducer gear reducer can not be self-locking, and the front one allows long-term operation, the rear one does not allow long-term operation of the transmission reducer brand. The front one has higher transmission efficiency, while the rear one has lower transmission efficiency, which means that the front one has less heat and the rear one has more heat, which requires a lot of lubrication.
