Production Process of 320t Overhead Crane for Casting Use

Brake - Crane Accessory

1. Application scope: Moving parts deceleration.

2. There are two types: friction brake and non-friction brake.

3. Crane brake is mainly constituted by brake pad, brake arm, brake wheel and brake releaser.

4. To reduce the braking torque and the size of brake frame, the brake is usually installed on the high-speed shaft. To meet the needs of high safety for large machinery, like mine hoist and elevator, the brake should be installed on the low-speed shaft which next to the working parts the large machinery.

Bearings used on Cranes

Bearings used on Cranes

1. There are two types: rolling bearing and sliding bearing. Rolling bearing has various standards and series, but its radial dimension, vibration and noise is bigger and its price is higher than the sliding bearing.

2. Rolling bearing is mainly constituted by outer ring, inner ring, rolling elements, bearing cage, seal and lubricant. Basing on the shape of rolling elements, rolling bearing is divided into two kinds: ball bearing and roller bearing.

Coupling on Crane

Pairs of Gear Coupling

1. Application scope:  Connecting different mechanism

2. It’s constituted by two parts. One connects the drive shaft, another connects the driven shaft.

3.  It’s the most used connecting components in shafting transmission of machinery.

4. There are two types: Fixed coupling and movable coupling.

5. In high-speed and heavy-load power transmission, some couplings could buffer and absorb shock to improve the dynamic performance of shafting.
