Product Description
Bushing system that can be attached and detach from shaft with one spanner. To install the optional MB bushing is required.
[Features]
· Can be easily attached to the shaft of the pulley with a single spanner.
· Easy to detach, reducing man-hours.
· When installing on the shaft, insert smoothly and tighten bolt securely using the taper, with no fine movement wear at the fitting part during use, extending the life of the shaft.
· Since the bushing has machined shaft hole and keyway corresponding to the standard shaft diameter, addition machining at the time of use is not required.
· Labor-saving of shaft hole machining, machining accuracy inspection, transportation for machining, etc. helping to reduce man-hours and shorten the lead times.
· Changing the position of the rotating body such as the pulley on the shaft is smooth, and centering can be done easily.
· The boss width can be designed small, relative to the shaft hole, for reduced pulley weight.
· Even with castings, the material can be made uniform by decreasing the thickness of the boss part.
· The Mitsuboshi belt wedge pulley is a standardized pulley, employing a bushing system.
· The bushing system can also be horizontally deployed to couplings, gears, sprocket wheels, etc.
Product Specification
Principle Diagram and Structure of the MB Bushing System
To use the Maxstar wedge belt more effectively, the bushing system was adopted to standardize the pulley. Easy to install and remove on the shaft with just one wrench. The bushing system can also be horizontally deployed to couplings, gears, sprocket wheels, and more.
a: Insert the bushing along the keyway. Safely and reliably transmits torque.
b: Utilizing the taper provides a strong fit.
c: Securely attaches to the pulley with tightening bolts.
d: Adding a slot allows the shaft to be tightened more firmly.
e: Removing the bushing pulley from the shaft can be easily done by moving the tightening bolt to the tapped hole.
- 1.First, perform a simple clearance fit.
- 2.By tightening the tightening bolt, the same effect as an interference fit can be achieved.
There is no need for the various processing steps required in methods such as shaft hole processing; by tightening the tightening bolt with a clearance fit, the same effect as an interference fit can be obtained.
Mounting method from the shaft
Insert the bushing into the pulley and loosely thread the bolt by hand.
Mount the bushing pulley onto the shaft.
(The fit is smooth.)
Using a torque wrench, securely tighten the tightening bolt.
(This will achieve a complete fit.)
- 1. The tightening torque for the bolts should follow the table below.
- 2. When tightening the bolts, tighten them evenly to avoid uneven tightening.
- 3. Wear protective equipment such as gloves when installing or removing parts.
■ Bolt tightening torque table
| Bolt diameter | Bushing type | Tightening torque MAX |
|---|---|---|
| M6 | G, H | 9.8N⋅m |
| M8 | P1 | 18.6 N⋅m |
| M10 | Q1, Q2, R1, R2 | 32.3 N⋅m |
| M12 | S1 | 69.6N⋅m |
| M16 | U0·U1 | 138N⋅m |
| M20 | W1 | 240 N⋅m |
How to Remove from the Shaft
Remove the tightening bolt.
Thread the bolt into the removal tap on the flange section.
Remove the bushing pulley from the shaft.
