PBL has established its name as the most trusted and accepted name for its geared motors and inline gear reducers in all the industries since last more than thirty years. Originally started under technical collaboration from renowned German manufacturer Rudolf Muchan KG, Power Build has made a lot of improvements not only in the manufacturing process but also in materials and design technology. As a result of continous research and development in the field of mechanical power transmission equipment, understanding individual application and working out the most suitable and economical solution, PBL continues to maintain leadership in the market. Power Build is happy to release this new catalogue incorporating in it, the essence of its long experince and expertise in the field. The field. This catalogue supersedes all its earlier catalogues for helical geared motor PBL Helical inline geared motors are manufactured in a modern manufacturing plant of latest generation CNC machines conforming to all relevant standards under effective quality assurance system. Electric Motors and helical gear boxes are built as one unit to give a coaxial and compact construction. Power Build Helical Geared Motors and Gear Reducers are available in foot, flange, foot-cum-flange and hub type construction.
Features:
GEAR CASE
The reduction gear trains are housed in a sturdy gear case of one-piece construction cast integral with its pedestal and internal partition wall which serves as both reinforcement and bearing housing. Gear case is manfatured from close grained cast iron and has ample surface area for heat dissipation.
GEAR AND PINION
The reduction gear trains are housed in a sturdy gear case of one-piece construction cast integral with its pedestal and internal partition wall which serves as both reinforcement and bearing housing. Gear case is manfatured from close grained cast iron and has ample surface area for heat dissipation.
OUTPUT SHAFTS
Output shafts of both geared motors and gear reducers and input shaft inline gear reducers are manufactured from best quality medium carbon steel for high overhung load carrying capacities. For special applications, these shafts can also be heat treated
LUBRICATION
The lubrication of gears and bearings is fool-proof, being achieved automatically by splash of oil. Thus, no special are is required except occasional topping up of the oil to required level. A large oil filler-cum-breather, oil level indicator and drain plug are provided on the gearbox.
ELECTRICLAS
Electric motor provided with geared motor is TEFC squirrel cage induction motor suitable for operation on 415V, 3-Phase, 50 C/s AC supply as per IS : 325. All motors are provided in IP 55 enclosure and F/B class insulation. Geared motor fitted with electric motor of special design like flame proof, crane duty, extended shaft on NDE, brake etc, can also be offered.
MANUFACTURING STANDARDS
All output shafts are manufactured as per DIN 42948. Tolerance for shafts diameters may varyas per IS, k6 upto 50mm and m6 above 50mm. Keyways and keys are as per DIN 6885 with keyway tolerance P9. Key steel DIN 6880. Threading on output shafts is as per as DIN 332/1943. Output speed tolerance is ±3%
TESTING
All components are throughly inspected at various stages and assembled unit is tested on ‘no load’ for noise level, oil leakage, output speed and temperature rise.
