Description

Gear is a common part, which is often used in mechanical transmission. The gear is made of high-quality high-strength alloy steel, carburized and hardened on the surface, with strong bearing capacity and durability. In practical applications, due to the smooth transmission of helical gears, there are many types of gear transmissions for shock, vibration and noise. Among them, the efficiency of helical cylindrical gears is very high, for example, the efficiency of straight cylindrical gear transmission is lower than that of helical cylindrical gear transmission. The helical cylindrical gear is the same as the straight cylindrical gear mechanism. The helical cylindrical gear can use the method of reducing the center distance a so as to improve the bearing capacity of the transmission and can be used at high speed. The helical gear reducer is a novel reduction transmission. The helical gear reducer has the characteristics of small size and light weight, and good economy and small size, so it is widely used in high-speed and heavy-load occasions.

Helix angle: it refers to the angle between the teeth of the helical gear and the axis.

Helix angle is a unique feature of helical gears and does not exist in spur gears, that is, straight gears. Generally speaking, the helical angle of the helical gear we usually refer to the helical angle on the indexing cylindrical surface. The larger the helix angle, the greater the degree of coincidence, the more conducive to the smooth movement and the reduction of noise. Everything is two-sided. Although increasing the helix angle brings many advantages, the axial force generated during work also increases, so the size should depend on the quality requirements and processing accuracy of the work. Generally, 8-25 is used. If there are special requirements for noise, a larger value can be adopted according to the situation.

Determination of the spiral direction: first, we make the axis of the gear vertical. If the right side of the spiral is high, it is right-handed; otherwise, the left side of the spiral is high, it is left-handed.

Disadvantages and Corrections

The manufacturing of double helical gears is troublesome. The axial component force is harmful to gear transmission, it increases the friction between the devices, and makes the devices easy to wear or damage. The main disadvantage of helical gears is that they produce axial component forces when the gears mesh. The axial force is caused by the helix angle. The larger the helix angle, the greater the axial force. In order to prevent the helical gear from generating excessive axial force, it is generally taken as 8 to 15 when designing. The double helical gear can reduce the influence of axial force component, but the manufacturing of double helical gear is more troublesome. The uneconomical helical gear transmission is composed of two helical gears meshing.

Usage: To transfer the motion between two phases in the wrong axis in space.
