Design News for Mechanical and Design Engineers

Protective covers for hydraulic hose assemblies are taking on a whole new meaning. They are still being used to protect hoses on mobile construction and mining equipment. However, with the need for higher-pressure systems and more compact machine designs, design engineers are increasingly looking for ways to safely protect machine operators and personnel from catastrophic hydraulic hose failure.

Any loss of power is a loss of money for users. To minimize losses and keep energy consumption in check, power transmission drives must operate at optimum efficiency.This paper compares the efficiency-related characteristics of two belt drives, V-belt drives and synchronous belt drives to show the potential for savings.

Leaking hydraulic couplings create headaches for industrial and mobile equipment manufacturers and users alike. Hydraulic leaks on new equipment mean costly rework or warranty claims. In the field, leaks pose environmental, safety and operational problems. Must we take leaks for granted on standard coupling designs? Not necessarily. New advances in technology have made the widely-used JIC hydraulic coupling much more leak free. The answer lies in the design of the Full-Torque Nut™ coupling.

New and Improved and Environmentally Friendly. Same Salt-Spray Resistance, Now Earth Safe Following up on our introduction of our industry leading TuffCoat plating in 2001, Gates is pleased to announce another important product enhancement - the elimination of hexavalent chrome from our TuffCoat plating process.

Gates introduced EnviroFluid hydraulic hose to the market three years ago. We will soon be consolidating our high pressure spiral wire hose line to the EnviroFluid construction. This FAQ will guide you and your customers through the innovations that Gates brings to the market with this new spiral product range.

Hydraulic system cleanliness is a term used to describe the level of solid and liquid contamination found in hydraulic systems. Contamination may be defined as any substance that is not part of the hydraulic system's working fluid. Several sources claim that over 70% of hydraulic system failures are due to contamination.

The vast number of hydraulic applications demand numerous sizes and constructions of hose to satisfy individual working requirements and conditions. Because of this, hydraulic hose varies in weight, size, temperature ratings, numbers and type of reinforcement layers, rated working pressure, flexibility and economics.

This program will enable you to answer basic airflow problems involving Gates hoses, involving air compressors. The equations used for this program are based on assumptions and average conditions. This should be used as a guide only.

The nomographic chart can be used as a guide in selecting the correct hose size for a given hydraulic system. The velocity of the fluid should not exceed the recommended ranges on the nomographic chart.  If velocity exceeds recommendations, turbulent conditions occur with an increase in pressure loss and heat. With the known flow and pressure range, this graph can help select the right hose size.
