1 Spiral Bevel Gearboxes Type BG General Spiral bevel gearboxes BG incorporate the most modern advances in bevel gearbox design and construction. These gearboxes offer an extensive range of ratios together with an excellent power to size relationship as well as low noise levels even at high speed operation. 1. Construction Features - The gearbox, which is made in cast iron, is of cuboid design with all external faces machined and with threaded fixing positions on each face (useable depth of threaded hole = twice the diameter). - Input and output covers and housings are supplied with two location spigot diameters (h7) together with threaded fixing holes (except size BG75) for possible co-axial fixing. - The alloy steel spiral bevel gears are cut in the GLEASON system, case hardened, tempered and lapped to the exact mounting position. - Input and output shafts are manufactured in hardened and tempered steel with all surfaces ground. - Input and output shaft tolerance (j6). Hollow shaft tolerance (H7). - All shafts supplied with threaded end to UNI DIN Keyways to UNI DIN On request and dependent upon speed type BG spiral bevel gearboxes may be assembled with minimum backlash. Due to the quality of the gears and machining tolerances, an overall efficiency of between 94 & 97% can be expected. The modular construction of BG spiral bevel gearboxes permits up to six input/output shafts (except ratio 1:1). 2. Lubrication BG spiral bevel gearboxes are supplied grease lubricated for input speeds up to 1000rpm, for higher speeds or on request oil lubrication is available. In this case the gearboxes will be supplied with a filler/breather plug, level indicator and drain plug. Filler, level and drain positions are indicated as follows: Filler/breather plug Level indicator plug Drain plug Motorised spiral bevel gearboxes, reversing bevel gearboxes and disengaging bevel gearboxes are usually oil lubricated. For high speed and/or high ambient temperature conditions it may be necessary to apply external cooling. Please consult T.E.A. 68

44 Reversing Spiral Bevel Gearbox Type I0 90 Degree Reversing Spiral Gearboxes 90 degree reversing spiral bevel gearboxes are available with ratio 1:1 and 2: 1 only. By moving the control lever from fully engaged through neutral to fully engaged in the opposite direction the 90 degree shaft will change rotation. Operation of the lever is normally carried out by hand and should only be done when the unit is stationary. Engaging position is usually indifferent, and reversing spiral bevel gearbox is called FP (Full Position). On request these gearboxes can be supplied with the option SP (Single Position) which means a single engaging position on 360 degrees. Reversing bevel gearboxes are produced in sizes BG32, BG42 and BG55 only. Selection corresponds to input kw and output torque as shown on pages 70-71, reduced by 30%. Dimensions and mounting positions are the same as for Type A (Pages 78-79) and Type DR (pages 90-91) 110

45 Disengaging Spiral Bevel Gearboxes Type D0 Disengaging spiral bevel gearboxes are manufactured in ratios 1:1, 2:1, & 3:1 only. Operation of the lever disengages the 90 degree shaft. This is normally carried out by hand and should only be done when the unit is stationary. Disengaging spiral bevel gearboxes are produced in sizes BG32, BG42 and BG55 only. Selection corresponds to input kw and output torque as shown on pages 70-71, reduced by 15%. Dimensions and mounting positions are the same as for Type A (Pages 78-79) and Type DR (pages 90-91). 111

46 Co-Axial Reversing Spiral Bevel Gearboxes Type IC Co-axial spiral bevel gearboxes are manufactured in ratios 1:1 only. By moving the control lever from fully engaged through neutral to fully engaged in the opposite direction the co-axial shaft will change rotation. On request co-axial reversing spiral bevel gearboxes can be supplied with a third projection shaft at 90 degrees. Operation of the lever is normally carried out by hand and should only be done when the unit is stationary. Co-axial reversing bevel gearboxes are produced in sizes BG32, BG42 and BG55 only. Selection corresponds to input kw and output torque as shown on pages 70-71, reduced by 30%. Dimensions and mounting positions are the same as for Type A (Pages 78-79) and Type DR (pages 90-91). 112

47 Mounting Flange - Type FC (Male Spigot) The mounting flange can be supplied with female spigot D, leaving dimension M unchanged
