What is the generator one-way pulley

"OAP" is short for one-way pulley
Unidirectional alternator pulley is also called alternator overrunning pulley, which is called overrunning alternator pulley in English
Commonly known as the generator belt clutch, in fact, it refers to the belt pulley of one-way alternator.
The one-way belt pulley of the generator is composed of an outer ring matching the cross-sectional shape of the multi-wedge belt, a clutch unit composed of a stamped inner ring, an outer ring and a double needle roller bearing, a shaft sleeve and two sealing rings. In order to prevent the influence of water and other dirt, a protective cover is installed on its outer end face.

What is the generator one-way pulley

Its function is to decouple the alternator from the front engine accessory belt drive train, because the alternator has the highest rotational moment of inertia in the front engine accessory belt drive train. This means that the generator one-way pulley is a V-belt and can only drive the alternator in one direction

What are the characteristics of the generator one-way pulley, what are the differences with the traditional generator pulley, and how to distinguish the true and false one-way pulley?

1. It has one-way slip performance, and its basic principle is similar to the one-way clutch gear on the starter

2. It can be divided into outer ring and inner ring. If the inner ring speed (i.e. rotor speed) exceeds the outer ring speed during operation, the pulley will slip immediately, and the inner ring and outer ring will be separated.

3. There is a plastic cover on the port to prevent dust from entering the interior, commonly known as dust cover.

4. Rotate directly on the rotor shaft by relying on the thread on the back. Therefore, there is no hexagon nut on the outer end face of the wheel

5. The ordinary pulley is triangular and the unidirectional pulley is wedge-shaped, so that the generator has good performance in operation

6. It must be fixed or removed with special tools: due to the particularity of the structure, the new pulley must be tightened or removed with special tools. The main part of the special tools is the mandrel matching the teeth in the pulley (the outer diameter of the mandrel is 19.99mm, and the number of teeth of the mandrel is 33 teeth)

7.Standard screwdriver head must be used: (1) optional Ф 10. 12 point bit, length 70mm. (2) Optional Ф 10. 6-point bit. The length is 70mm.
