Features and Application

H Series Right Angle Pump Drive can transmit the prime mover horizontal axis power to the vertical pump axis, which is economical, efficient, space-saving and suitable for various climatic conditions. 


H Series Right Angle Pump Drive is directly matched with diesel engine, horizontal motor or steam turbine, which can be used for transmission and speed change of various vertical pumps such as long-axis pump, deep well pump, diagonal flow pump, axial flow pump and submerged pump as well as the right angle transmission and speed change of various vertical axis machines. The H-series right angle gearbox can directly support the axial forces that may exist in the machine and simplify the structure of the machine. Can be widely used in farmland irrigation, water conservancy engineering, municipal engineering, metallurgical mine, petrochemical engineering, fire control and marine engineering, etc. 


A variety of models and transmission ratios can meet the requirements of high and low speed prime movers and pumps.

Selection of Parameter

When it is used to drive deep well pumps, the parameters in Table 2 already contain suitable load factors, which can be directly selected by the user. For other situations, please consult our company. 

The American Gear Manufacturing Association stipulates that the spiral bevel gear load factor shall be greater than or equal to 1.5, and the load factor values shall be different for different applications. In addition, other factors affecting the rated power of the gearbox include bearing, axis, temperature and lubrication, which have been taken into account in Table 2. 

The selection of oil cooling method should take factors such as thrust, speed, ventilation environment and operating conditions into account. For a gearbox equipped with an oil cooler, it shall be operated with a coolant of about 20 ℃. 


Selection of Thrust Bearing Form

The upper part of the vertical axis (hollow axis) is made of bearings that can withstand large thrusts, which can meet the requirements of most pumps and different heads. In most cases, the thrust of the gearbox itself is mainly used to reduce the load that the pump acts on the "thrust bearing" of the vertical axis, so there is a minimum downward thrust to prevent the vertical axis "thrust bearing" from separating. 

Unless otherwise noted, H-series gearbox is generally arranged in the DT format shown in the figure, corresponding to the "standard" thrust shown in Table 2. 

If there is insufficient "upward thrust" or "downward thrust", it can be arranged in the DF format shown in the figure, corresponding to the "two-way" thrust shown in Table 2. 

If the "downward thrust" exceeds the standard thrust value shown in Table 2, it can be selected by heavy type, corresponding to the DT/DT arrangement format shown in the figure. 

The heavy type can also be arranged according to the DF/DT format shown in the figure. At this time, the downward thrust corresponds to the "standard, thrust value" in Table 2, and the upward thrust is selected according to "two-way" in Table 2.
