7.1 Type overview Type HDV – Hygiene-design bevel gearboxes Gear ratios: i = 1:1 to 6:1 Maximum output torque: 430 Nm 4 gearbox sizes with edge lengths of 065 to 140 mm Low-backlash construction < 10 angular minutes possible All outside parts made of VA steel

The HDV-series gearboxes are intended for the use in food and pharmaceutical industries (including offshore and rough conditions). They are based on our proven standard gearboxes from the range of single-stage bevel gearboxes (V series) and have therefore the same external dimensions. They vary in the following features: • All outside parts are made of high-quality stainless steel. • The shaft seal rings installed in the type have an additional dust lip. • The housing and the flanges do not contain any bores or other dust pockets. • Required mounting bores will be drilled application-specifically...

7 Hygiene-design gearboxes The standard version of the mounting / fastening has the order code 0. Example of order code: HDV 090 1:1D0 1.1 500/0000 The size and the position of the threaded mounting holes correspond to those of the type V (page 29 and following) HDV 065 Thread size The gearboxes can be used in all installation positions. The recommended installation position is the position in which the shafts are horizontal. These are the installation positions 1 and 2. The installation position is defined by the gearbox side directed downwards during operation and will be indicated by the corresponding...

7.2.11 Low-backlash construction For low-friction running, the tooth space in the gear set is manufactured larger than the tooth. When the direction of rotation is changed, this results in a rotation angle until the counter-rotating tooth flanks contact each other. This rotation angle is called circumferential backlash. Circumferential backlash, measuring method The circumferential backlash is measured after the drive shaft (N1) has been fixed. A force of around 2% of the nominal torque is applied to the output shaft (N2) in both rotational directions. A tooth backlash will result between the...

The mass of the gearbox may deviate depending on the gear ratio. The permissible radial forces depend on torque, rotational speed and direction. They must be calculated for the respective case of application. Please enquire these. Permissible radial force Fr2 and axial force Fa2 on shaft N2 < 12 The mass of the gearbox may deviate depending on the gear ratio.

Implementation VV The dimensions of the Models not shown can be figured by mirroring available dimensions.
