Bevel gear box SB, FB and TB Series miter gears

Answering your needs with a rich product lineup and a record of success

These bevel gear boxes have been successful throughout the power transmission field as a result of flexible combinations of attachment configurations, shaft layouts and rotation directions as well as in combination with other machinery such as screw jacks.

Bevel gear box SB, FB and TB Series miter gears

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.
[SB Series]

[SB Series]


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.

FB Series bevel gear box

Features
Tough design This design is strong enough to provide the durability required for industrial machinery subjected to severe usage.
Compact and light weight This design has been optimized to be lightweight and compact.
A wide variety of options - Shaft layout: 6 varieties
- Models: 5 varieties
- Speed ratios: 3 varieties including 1:1, 1.5:1, 2:1
Select the optimal model for each application.
Applications - Agricultural machinery
(Often used in working equipment for tractors in particular)
- Industrial machines
(Used for changing shaft direction and splitting power)
[FB Series]

[FB Series]


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.
[TB Series]

[TB Series]


Structure
