Embodiment Construction

[0032] See now attached drawings especially figure 1 and 4 , an embodiment of a modular gear transmission system according to the present invention is generally indicated at 30 . A gear transmission system 30 transmits power from a motor 32 to a device 34 that requires power to perform work. In the illustrated embodiment, device 34 includes a pump. However, it should be understood that the device may be any powered device without departing from the scope of the present invention. A gear transmission system 30 is operatively connected between a rotational output shaft 36 of the motor and a rotational transmission shaft 38 of the pump. The gearing system regulates the speed and torque between the shafts such that the drive shaft 38 turns at a different speed and carries a different torque than the motor output shaft 36 . The gear transmission system 30 includes a gearbox 40 , a first gear set assembly 42 (eg, a planetary gear set assembly), and an optional second gear set as...

Abstract

A modular gear system for transmitting power from a motor to a device such as a pump which requires power to operate. The system includes a gearbox and first and second planetary gearset assemblies connectable between an output shaft of the motor and a drive shaft of the pump. The system may be configured as either a single-stage mode wherein the first gearset assembly is received in the gearbox to produce a rotational speed adjustment between the shafts, or a multi-stage mode wherein both the first and second gearset assemblies are received in the gearbox and are connected in series to produce a different rotational speed adjustment. The system provides flexibility for different speed and power requirements and is adaptable to a variety of motors.

Description

technical field [0001] The present invention relates generally to variable speed systems for varying the rotational speed of mechanisms, and more particularly to a modular gear transmission system for pumps that allows for flexible selection of gear reduction ratios and drive motors. Background technique [0002] Mechanical pumps for conveying fluids are used in a variety of applications that may require various sources of power to perform their work. For example, pumps in industrial plant production equipment can be efficiently powered by alternating current (AC) electric motors. Pumps mounted on mobile units or mining equipment may need to be powered by brushed direct current (DC) motors, brushless DC motors or hydraulic motors depending on the equipment available. Typically, these motors have different operating characteristics, especially the rotational speed at a given power. In addition, pumps must meet a wide range of power and torque conditions depending on the spe...
