Angle planetary reducer is a type of planetary reducer. Because the motor input of the angle planetary reducer is at a 90 degree angle to the output shaft of the reducer, it is called an angle planetary reducer, also known as a right angle planetary reducer or a 90 degree angle planetary reducer. Shangying will now take you to see how the angle planetary gearbox is actually like this.
Due to the 90 degree right angle relationship between the input shaft of the motor and the output shaft of the right angle planetary reducer, the motor is usually installed parallel to the equipment, closely attached to the equipment, unlike parallel axis planetary reducers where the motor is perpendicular to the equipment. Right angle planetary reducers can save a lot of space, and they are usually installed directly on the equipment, with a 360 degree installation angle without dead corners, making installation flexible and versatile.
The characteristic of this type of reducer is that the direction of the input shaft and the output shaft are different. Usually, the angle between the input and output of a corner reducer can be 90 degrees. According to the type of gearbox, the shaft can be tangent on one level or intersect on two parallel levels, thereby achieving shaft offset.
There are angle reducers with different types of gears or angle reducers composed of different types of gear combinations. The most common types of reducers are helical gear reducers and worm gear reducers. Worm gear reducers can achieve self-locking by increasing the single-stage transmission ratio and reducing efficiency. Similarly, in worm gear reducers, the output shaft can be designed as a hollow shaft. There are various types of helical gear reducers. A helical gear reducer with intersecting axes has spur, helical, or spiral bevel gears. The hypoid helical gear reducer has a spiral bevel gear, and the axis intersects with the gear to achieve axis offset. The technically significant transmission ratio range achieved by hypoid gear reducers through bevel gear grades is greater than that of traditional bevel gears.
Similarly, helical gear reducers can also be combined with other types of reducers. A common application scenario is when combined with a planetary gearbox, which can be front or rear mounted. Thus expanding the range of total transmission ratios and widely used in industrial applications.
Usually, the efficiency of helical gear reducers is lower than that of coaxial cylindrical gear reducers, especially when compared to planetary reducers. This is because bevel gear grades generate high axial and radial forces, which are received through appropriate bearings. This increases power loss, especially in the drive stage of the gearbox.
The smoothness of operation and the torque that can be transmitted of traditional bevel gears are also lower than those of cylindrical gears. The hypoid gear reducer operates extremely smoothly and can transmit extremely high torque, but high bearing loads are generated in bevel gear grades.
If the installation space of the application is limited or the program has requirements for the angle allocation of the input shaft and output shaft, a corner type reducer or helical gear reducer should be used. If the output shaft is used for threading pipelines or using clamping kits, it can be used as a hollow shaft.
The advantages of angle reducer: it can be used in limited structural space; Compact structure; Can be used in combination with other types of reducers; When using a hypoid helical gear reducer, it runs smoothly and has high torque; There are specifications with hollow shafts available
Disadvantages of angle reducer: complex structure; Efficiency lower than planetary gearbox; Poor operational stability; Within the range of single-stage transmission ratios, the torque is relatively low.
