If you want to obtain a larger gear reduction ratio, you need to use a worm gear. The gear reduction ratio of the worm gear is generally , and sometimes even as high or greater.
Many worm gears have an interesting property not found in other gear sets. The worm can easily turn the gear, but the gear cannot turn the worm. This is because the angular angle on the screw is very shallow, and when the gear tries to rotate the screw, the friction between the gear and the screw keeps the screw in place. Module, pressure angle, worm diameter coefficient, lead angle, number of worm heads, number of worm gear teeth, addendum coefficient (taken) and top clearance coefficient (taken.). Among them, the module and pressure angle refer to the module and pressure angle of the worm shaft surface, that is, the module and pressure angle of the worm gear end face, and they are both standard values. The worm diameter coefficient is the ratio of the worm graduation circle diameter to its module.
Worm
Worm refers to a gear that has one or several helical teeth and meshes with the worm gear to form a staggered shaft gear pair. Its indexing surface can be a cylindrical surface, a conical surface or a torus surface.
Worm transmission is composed of a worm and a worm gear and is used to transmit motion and power between staggered shafts. Usually the staggered angle of the two shafts is. In general worm transmission, the worm is used as the driving part. In appearance, the worm is similar to a bolt, and the worm gear is much like a helical cylindrical gear. During operation, the worm gear teeth slide and roll along the helical surface of the worm. In order to improve the contact between the gear teeth, the worm gear is made into an arc shape along the tooth width direction so that it partially covers the worm. In this way, when the worm and worm gear mesh, there is line contact instead of point contact.
Worm gear
Worm gear mechanism is often used to transmit motion and power between two staggered shafts. Worm gears and worms are equivalent to gears and racks in their mid-plane, and worms are similar in shape to screws. Worm gears and worm mechanisms are often used in situations where two axes are staggered, the transmission ratio is large, the transmission power is small, or the work is intermittent.
Transmission characteristics
It can obtain a large transmission ratio and is more compact than the staggered shaft helical gear mechanism.
There is line contact between the meshing tooth surfaces of the two wheels, and its load-bearing capacity is much higher than that of the staggered-axis helical gear mechanism.
Worm transmission is equivalent to screw transmission and is a multi-tooth meshing transmission, so the transmission is stable and the noise is small.
, self-locking. When the lead angle of the worm is less than the equivalent friction angle between the meshing gear teeth, the mechanism is self-locking and can achieve reverse self-locking, that is, the worm can only drive the worm gear, but not the worm gear. For example, the self-locking worm mechanism used in lifting machinery has a reverse self-locking function that can provide safety protection.
, the transmission efficiency is low and the wear is serious. When the worm gear is engaged in transmission, the relative sliding speed between the meshing gear teeth is large, so the friction loss is large and the efficiency is low. On the other hand, the relative sliding speed increases the tooth surface wear and heat seriously. In order to dissipate heat and reduce wear, more expensive materials with good friction reduction and anti-wear properties and good lubrication devices are often used, so the cost is high. .
, the axial force of the worm is relatively large.
