Hydraulic axial piston motors

Product catalog summary
Overview: The document provides comprehensive details on explosion-protected axial piston motors compliant with the ATEX Directive 94/9/EC. These motors are designed for high-performance applications, offering high starting torque, efficiency, and adaptability for various industrial uses.
Specifications: The motors operate with high starting torques across a speed range of 1 rpm to 2,000 rpm without cogging. They can handle axial and radial loads directly and are suitable for demanding applications with potential high shocks, such as centrifuges and marine applications. They are fully ATEX certified for hazardous environments, including Zone 1 and Zone 21 (dust) and underground mining applications.
Performance and Efficiency: These motors achieve efficiencies up to 94% and are designed for low maintenance with robust construction. They feature low moment of inertia, are immediately reversible, and maintain full torque across the speed range. They are suitable for use with fire-resistant fluids and do not require counterpressure when operated as a motor.
Applications: Suitable for nuclear power plants, rolling mills, test benches, CNC machines, smelting and rolling mill equipment, shipbuilding, environmental technology, and materials handling equipment.
Technical Data: Detailed specifications for various motor series, such as AE3 to AE180, include information on displacement, torque, speed range, and pressure. The motors withstand high radial and axial forces and feature low leakage with built-in wear compensation.
Additional Features: Equipped with IEC electric motor interfaces for easy integration into existing systems. They offer energy recovery and storage capabilities and support control systems for feed and discharge operations.
Conclusion: The document highlights the motors' reliability, precision, and cost-effectiveness, making them suitable for demanding industrial applications. Their design and manufacturing precision ensure exceptional performance and reduced operational costs.
Functional Description: The motors operate on the wobble plate principle, converting hydraulic power into mechanical power. The speed is controlled by the hydraulic pump's volume flow, while the pressure difference adjusts to the required torque.
Advantages: Hydraulic drive concepts offer persistent motor cooling, high efficiency (up to 94%), energy recovery, low maintenance costs, and robust design. They provide stepless adjustable speed and torque, making them efficient and cost-saving solutions.
Graphical Analysis: Graphs illustrate torque curves, shaft strength calculations, and life expectancy of bearings based on load, gap, and pressure difference.
Procedures: Methodology for determining the service life of radial and axial bearings using life expectancy nomograms, with specifications and examples for calculating service life based on parameters such as radial load, gap, pressure difference, and speed.
Norms and Recommendations: Axial bearings cannot receive radial force. Ensure intercept points fall within permissible range for continuous or intermittent operation without flushing.
Company Overview: jbj Techniques Limited is known for strong relationships with customers and suppliers, indicative of high-quality service. They offer a wide range of products and are ISO certified, committed to international industrial standards, and provide ATEX certified products.

Due to the low amount of revolving mass, the rotational direction can be quickly changed, a feature very important in many test benches; when performing vibration tests on motorcycle forks or when testing the adjustment of wing flaps on aircraft. The components can perform up to 50 rotational direction changes persecond....

LSHT Hydraulic Motors AE3 - AE45 Series Axial Piston Motors Functional description All mentioned hydraulic motors in this catalogue are designed with a fixed displacement and work according to the wobble plate principle. The purpose of a hydraulic drive is to transfer hydraulic power in to mechanical power. Hydraulic power is created by the hydraulic volume flow as well as the pressure difference which is pending between the motors inlet and outlet. The mechanical power results from the speed, torque and efficiency of the motor which can be directly applied from the drive shaft. The required pressure...
