Product Overview:
Steering box, also known as commutator or steering gear, is a type of power transmission mechanism and a series of reducers, which has a wide range of applications in the industrial field. The steering box has now achieved standardization and diversified specifications. The steering box has single axis, double horizontal axis, single vertical axis, and double vertical axis options. Speed ratios of 1:1, 1.5:1, 2:1, 2.5:1, 3:1, 4:1, and 5:1 are all actual transmission ratios. The steering box can operate in both forward and reverse directions, with smooth low-speed or high-speed transmission. When the speed ratio of the steering box is not 1:1, the horizontal axis input and vertical axis output are deceleration, and the vertical axis input and horizontal axis output are acceleration.
Product Structure:
1. Shell: Made of high rigidity FC-25 cast iron;
2. Gear: Made of high-purity alloy steel 50CrMnT through quenching and tempering, carburizing and quenching treatment, and grinding;
3. Spindle: Made of high-purity alloy steel 40Cr quenched and tempered, with high suspension load capacity.
4. Bearing: equipped with tapered roller bearings with heavy load capacity;
5. Oil seal: Adopting imported double lip oil seal, it has the ability to prevent dust and oil leakage.
Performance characteristics:
1. The T series spiral umbrella gear steering box is standardized, comes in multiple varieties, and all speed ratios are based on actual transmission ratios, with an average efficiency of 98%.
2. The spiral bevel gear steering box is available in single axis, double horizontal axis, single vertical axis, and double vertical axis options.
3. The gear steering box can operate in both forward and reverse directions, with smooth low-speed or high-speed transmission, low noise, low vibration, and high bearing capacity.
4. When the speed ratio is not 1:1, the horizontal axis input and vertical axis output are deceleration, and the vertical axis input and horizontal axis output are acceleration.
Technical parameters:
Speed ratio range: 1:1 1.5:1 2:1 2.5:1 3:14:1 5:1
Torque range: 11.2-5713 Nm
Power range: 0.014-335 kW

Precautions before installation:
1. Before using the steering box, the installation shaft should be cleaned and checked for any scratches or dirt. If there are any, they should be completely removed.
2. The operating temperature of the steering box is 0-40 ℃.
3. Check if the fit size of the hole connected to the steering box meets the requirements, and the tolerance of the hole should be H7.
4. Before use, the blockage at the high position should be replaced with an exhaust plug to ensure that the gas inside the steering box is discharged during operation.

Installation and maintenance:
1. The steering box can only be installed on flat, shock-absorbing, and torsion resistant support structures.
2. Under no circumstances should a hammer be used to knock pulleys, couplings, small gears, or sprockets into the output shaft, as this can damage the bearings and shaft.
3. After installing the steering box, check if it is flexible. Please conduct a no-load test for formal use, and gradually load and operate under normal operation.
4. The steering box is strictly prohibited from being used beyond its rated load.
5. The oil level of the steering box should be checked before use and during operation to ensure it is normal.

Lubrication:
1. The initial period of use is two weeks or 100-200 hours, which is the initial wear period. During this time, there may be a small amount of metal wear powder particles. Please be sure to clean the interior and replace with new lubricating oil.
2. When used for a long time, replace the lubricating oil every six months to one year or 1000-2000 hours.
3. The lubricating oil for the steering box uses China Petroleum gear oil at 90-120 degrees Celsius. For low-speed and light load conditions, it is recommended to use gear oil at 90 degrees Celsius. For heavy load and high temperature conditions, it is recommended to use gear oil at 120 degrees Celsius.
