Shaft Mounted Gearboxes Manufacturer

We manufacture the shaft-mounted gearbox per the set international quality standards, which offers you speed reduction by directly mounting it onto the drive shaft. These proposed Shaft Mounted Gear Boxes are straightforward to install and remove.

Shaft-mounted gearboxes are fitted with electric motors, making them work faster than before. While manufacturing this Shaft Mounted Gear Box, we are driven by high-quality raw materials and complicated technology. The Shaft Mounted Speed Reducer Gearbox is facilitated with metallic double-lip oil seals. These help block out the dirt from the outside. All gear units are tested for gear cracks, noise, and leaks for a trouble-free operation. The gear units have an advanced tooth design to give a higher power-to-weight ratio for the same size gearbox.

TXT (SMRY/SMR) Series Shaft Mounted Gearbox

SMR series shaft-mounted gearbox, also called TXT series shaft-mounted gearbox or SMRY shaft-mounted speed reducer gearbox. The shaft-mounted gearbox can be directly fixed on the drive shaft of the equipment, and there is no need to fix the shaft-mounted gearbox on or on other foundations. This structure gearbox can also use one or two elastic couplings and the internal belt tensioning device; the screw buckle on the torsion arm can easily and quickly adjust the belt tension. The shaft-mounted gearbox can be lubricated with ordinary lubricating oil or equivalent synthetic oil.

DXG(ATA) Series Shaft Mounted Gearbox

The DXG series shaft-mounted gearbox is well-received by industries after becoming the best-selling mining gearbox. It is favored because its absolute reliability and low maintenance characteristics are critical factors in the mining and ore fields. The shaft-mounted speed reducer adopts a modular design that can be modified according to customer requirements. It can meet the needs of all industrial productions and is especially suitable for wind power products, couplings, gears, and other spare parts.

1. DXG(ATA) Series Shaft Mounted Gearbox Design Characteristics

The characteristics are as follows:
1). Uses low-carbon alloyed steel cementation processing completely.
2). The gear and the gear shaft precision is high.
3). The volume is small, and the torque is big.

2. Advantages of DXG(ATA) Series Shaft Mounted Gearbox

1. We use non-polluting sealed equipment to paint the housing. Thus the painting process will not pollute the environment.
2. The integrated high-temperature drying equipment improves painting efficiency and paint fastness. So in a violent collision, the appearance of the shaft-mounted gearbox will only suffer minimal damage.
3. Hardened reducer: high-quality forged steel materials, rigid cast iron box, high-frequency heat treatment on gear surface.
4. After precision machining, the assembled helical, bevel, or bevel-helical gear units are fitted with various motors to form mechanical and electrical integration, which fully guarantees the physical properties of the shaft mount reducer.
5. The shaft-mounted structure is easy to connection with working machinery.

3. Installation and Disassembly Gearbox

The following installation instructions must be followed.

1. Ensure that the gearbox is properly installed to prevent loosening. Install hydraulic couplings, torque limiters, etc., if necessary for use in situations of overload or vibration.

2. Before painting, there must be protective measures on the machining surface of parts and the outer surface of the oil seal to prevent the paint from drying on the rubber and damaging the sealing function.

3. Before the gearbox is used, it shall be ensured that the equipment connected with the gearbox shall comply with the relevant technical regulations.

4. Before starting the machine, ensure that the oil surface conforms to the assembly position specified by the gearbox, and the oil’s viscosity should be suitable for the gearbox. See Chart A4 for details.

5. For outdoor installation, Proper measures must be taken to protect the motor from rain or sun exposure.

6. Before assembly, each mounting surface must be cleaned and properly treated to prevent rust.
