1. A Illustration 1 Gear installation positions 2 2 Mounting the gear Due to the principle of the functioning of the gear the output shaft as well as the input shaft are subjected to variable torques The following must therefore be observed The gear must be mounted a rigid machined surface e The fixing bolts must be secured and if possible the position of the gear should be additionally fixed by means of dowel pins e The connection between the gear and the driven load must be direct free of play and torsionally rigid This also applies to the drive side of the gear 2 3 Gear operation The following should be observed with regards to gear operation e Elasticity and play in the driven masses can result in vibration and must therefore be avoided A possibly installed overload protection should be mounted the output shaft BWV_H T SG_E 5 16 2 QUALIT T IN KURVEN AUTOMATIONS SYSTEME GMBH Lilienthalstrake 21 D 64625 Bensheim 3 Start up 3 1 Gear function HEINZ gears form a compact robust unit which through the use of accurately calculated globoidal cams enable the transformation of a constant input speed into an optimum precise and impact free intermittent output movement The cam rollers fitted in the turret are guided precisely in the globoidal curve by the hardened and ground cam path This cam path is formed with a variable slope and is divided into a dwell2.
