Product Description

Product Description

I. Core definitions of AK and BK pulleys

1. AK pulleys-Structural features:

Shaft bore is conical (Conical Bore) Conical Bore: The internal bore of the pulley body is conical in design (usually used in conjunction with a conical sleeve) and needs to be connected to the shaft through the conical sleeve.

Installation method: rely on the taper sleeve to hold the shaft (similar to the 'tightening sleeve' principle), without machining the keyway, through the bolt to tighten the taper sleeve to achieve the fixation.

Applicable scenarios: equipment requiring quick installation, adaptation to various shaft diameters or frequent maintenance (e.g. mining machinery, fans).

Typical identification:

Example of model: AK 50 (indicates AK type pulley with a reference diameter of 50mm).

 

2. BK pulley-Structural features:

Cylindrical Bore: The internal bore of the wheel body is straight (smooth cylindrical bore). The shaft is connected to the pulley by means of a keyway and a key.

Mounting: key transmission of torque (similar to conventional pulleys), keyway in the shaft bore (e.g. DIN 6885 keyway).

Scenarios: Stationary equipment (e.g. motors, gearboxes) with a machined keyway in the shaft, or where high torque transmission is required.

Typical designation:

Example of model: BK 80 (indicates a BK type pulley with a reference diameter of 80 mm).

Comparison items  AK belt pulley BK belt pulley
Shaft hole shape  Conical (requires conical sleeve) Cylindrical (requires keyway)
Installation method  The conical sleeve clamps the shaft and does not require key slots Key connection, dependent on the keyway on the shaft
Axial diameter compatibility  It can be adapted to different shaft diameters by replacing the conical sleeve A custom belt pulley is required for the fixed shaft diameter
Maintenance convenience  Quick disassembly and assembly, suitable for frequent maintenance Assembly and disassembly require moving the shaft or removing adjacent components
Torque transmission  Depends on the friction force of the conical sleeve (requires correct tightening of bolts) Mechanical meshing dependent on the key (torque transmission is more direct)
Typical applications Used in mining machinery, fans, conveyor belts (needs to be flexibly adapted) Motor, reducer, fixed equipment (high torque scenarios)
Typical applications of AK pulleys  Typical applications of BK pulleys 
Mining crushers  Electric motors and reducers 
Fans / conveyor belts  High-torque equipment 
European standard cone sleeve system American standard / general equipment

Sprocket way to install
1.Before assembling the transmission device, check the sprocket groove to ensure there are no scratches or sharp edges, and all dimensions should comply with the standards.
2.Clean the dirt from the mating surfaces of the shaft, cone sleeve, and sprocket, and then attach the cone sleeve and sprocket onto the shaft.
3.The toothed half-hole on the sprocket matches the non-toothed half-hole on the cone sleeve (this hole is called the installation hole and is indicated in Figure 3, with 2 such holes on the 1008-3030 cone sleeve and 3 on the 3525-5050 cone sleeve). The non-toothed hole on the sprocket matches the toothed hole on the cone sleeve (this hole is called the disassembly hole and is indicated by· in the figure, with 1 such hole on the 1008-3030 cone sleeve and 2 on the 3525 cone sleeve).
4.Move the cone sleeve to the ideal position, gently pull the sprocket onto the cone sleeve, and insert the internal hexagonal bolt into the installation hole.
5.Use a hexagonal wrench to gradually tighten each bolt alternately until the torque shown in Table 1 is reached. (Note: To ensure a tight fit, each bolt must be evenly tightened.)
6.If a keyway is to be assembled, first place the key in the keyway of the shaft, and then assemble the cone sleeve.
7.After running the lower drive for a period of time, stop the machine and check the tightening degree of the bolts.

Disassembly 
1. Loosen all the bolts. Remove one or two bolts according to the number of the disassembly holes. Lubricate the bolt threads and the bolt tips with oil. Insert the bolts into the disassembly holes as shown in Figure 3.
2. Tighten the bolts alternately until the cone sleeve and the pulley are released.
3. Remove the cone sleeve and the pulley from the shaft (if the cone sleeve and the shaft are too tightly attached, use a flat screwdriver to gently enlarge the straight slot of the cone sleeve. Do not exert excessive force to prevent the cone sleeve from bursting.)
