: |
Available 50 different shaft arrangement for many different kind of mountings. Also,two ratios, 1/1 and 1/2 for suitable applications.
|
|
Specially selected material is used for spiral bevel gear.Gear is rapping finish after heat treatment to ensure the quality.
|
|
Material of shaft is heat-treated carbon steel to resist strong bending moment.
|
|
Using tapered roller bearing to resist radial and thrust load on each shafts.
|
|
"A" shaft is single support and "B" shaft is both end support (In case of model with bearing housing, "B" and "C" shaft are single support)
|
|
Housing made of cast steel.
|
|
Lubrication is oil bath lubrication system, splash sufficient oil to the gear and bearing.
|
|
For sealing, used oil seal for rolling parts and O-Ring with liquid packing for opening area to ensure preventing leakage.

SB Series bevel gear box
Features
| Quiet operation |
The SB Series offers high-speed rotation and smooth operation. |
|---|
| Compact and light weight |
Take advantage of large capacity in a compact and light weight design. |
|---|
| Powerful and tough |
In addition to the gears and bearings, sufficient care has also been taken to provide strength and ensure enough power and toughness to provide many years of durability. |
|---|
| A wide range of uses |
50 different shaft layouts are available to respond to any possible mounting scenario. Gear ratios can be selected to match the application with 1/1 and 1/2 available. |
|---|
Structure
This series uses a spiral bevel gear. After a special steel is heat treated, it is finished with lapping to improve accuracy.
The shaft is made of heat-treated carbon steel in order to provide sufficient durability versus bending force.
A tapered roller bearing is used to receive the radial load and thrust load of each shaft.
The shaft layout is such that shaft "A" is supported with cantilever support while shaft "B" is supported from both sides. (However, in units with bearing housings, both shafts "B" and "C" are supported with cantilever support.)
The housing is a strong cast steel box.
Bevel gear boxes are lubricated with oil bath lubrication. The bottom of the gear case is an oil reservoir and as a part of the gear rotates through the oil, small droplets of oil are splashed throughout the inside of the gear case and lubricate the gear and bearing.
Bevel gear boxes use an oil sheet to seal the rotating parts and an O-ring or liquid packing for fixed parts to ensure that liquids do not leak outside.

Structure
This series uses a straight bevel gear. A special steel is heat treated, ensuring sufficient durability for high transmission capacity.
The shaft is made of carbon steel or a specialty steel in order to provide sufficient durability versus bending force.
A tapered roller bearing is used. Cantilever support is provided for shaft "A" and double-sided support is provided for shaft "B." The bearings receive the thrust and radial load of each shaft.
The housing is manufactured from gray cast iron.
This series uses oil bath lubrication.
TB Series bevel gear box
Features
| Light weight and durable |
The case is manufactured from a corrosion resistant aluminum alloy with a baked finish for superior durability combined with light weight. |
|---|
| Flexible installation direction |
It is possible to install the unit in any direction and installation is easy. |
|---|
| Low noise and high efficiency |
A spiral bevel gear is used that is heat-treated before lapping to produce smooth operation. |
|---|
| Maintenance free design |
Long-term use is possible because the unit is filled with high-grade grease. |
|---|
| Usable with special products |
When an application requires corrosion resistance, Makishinko can also use stainless steel for the shaft. |
