The Reliance catalogue gearbox range includes planetary, bevel and hypoid gearboxes, which provide housed, modular solutions, as well as an epicyclic gear module, which can be used in single or multiple stacks to build a customised gearbox.
We also provide design, manufacturing, assembly and test services to create custom gearbox solutions, designed to specification.
Reliance Planetary Gearboxes are designed specifically to suit NEMA 17 and NEMA 23 motors. They are ideally suited to work with the Reliance Cool Muscle intelligent servo system in high torque applications where positional feedback is important.
Ratios from 3:1 to 512:1 with maximum output torques up to 123Nm. The RGPN70 low backlash unit offers less than 3 arc minutes of backlash.
Precision machined gear profiles, case hardened and honed for higher load capacity, low noise, minimum wear and consistent backlash.
A balanced motor shaft clamping ring allows high input speeds up to 18,000rpm
Reliance Bevel and Hypoid Gearboxes provide an economic, space saving solution for right angle motion in a restricted space envelope.
Bevel Gearboxes are available with either single or double output shaft configurations with either 1:1 or 2:1 ratios. The BE Series is a small, compact, anodised aluminium unit, with removable, plastic, clip-on cover. The BS Series is a one-piece, slim-line aluminium housing wiht a completely sealed casing providing a dust free and safe operation, with pre-tapped holes for alternative easy mounting. Using high quality bevel gears the backlash of an assembled gearbox is as low as <20 arc minutes. Lubricated with high quality grease giving lifetime lubrication and low maintenance.
Reliance Hypoid Gearboxes are suited to higher ratio requirements between 5:1 and 10:1. Fully sealed with an aluminium housing and carbon steel gears and shafting. Mounted in ball bearings the unit is fully lubricated and sealed for life.
Reliance Epicyclic Modules are available in ratios of 3:1, 4:1 and 5:1. Their unique design allows the units to be stacked together providing higher ratios.
Efficiencies of 98% per single unit and 95% for two units coupled together are achievable.
The inherent problem of load sharing with planetary gear systems is solved by the use of pitch disks which are designed to equalise the load of each planet gear.
