BEVEL HELICAL GEARBOX

Product catalog summary

Characteristics
The bevel helical gearbox is available in multiple sizes with options for 2 or 3 reduction stages. It offers three input types: projecting input shaft, pre-engineered motor coupling, and compact motor coupling, with exceptions for sizes 56 and 63. The casing is made from aluminum alloy or cast iron, providing rigidity and ease of positioning. Gears are crafted from case-hardened steel, and high-quality tapered roller bearings support high radial and axial loads. A standard hollow output shaft and optional output flange enhance versatility.

Designation
The designation system includes various parameters such as gearbox type, input type, size, gearing, ratio, motor coupling, execution, mounting position, output flange, backstop device, shrink disk, and additional input.

Direction of Shaft Rotation
For horizontal gearboxes, reversing the output rotation direction is possible by rotating the gearbox 180° around the input shaft. Vertical units can be ordered with a specified rotation direction.

Additional Input
The input shaft can be mounted horizontally or vertically, except for sizes 56 and 63. A second input can be added with options TA, TC, or TF.

Efficiency
Efficiency is estimated based on the number of reduction stages, with minor variations due to size and ratio being negligible.

Input Speed
Performance calculations are based on an input speed of 1400 min-1, with permissible speeds up to 3000 min-1. It is advisable to keep speeds below 1400 min-1.

Thermal Power
Thermal power values are provided for each gearbox size, considering synthetic oil ISO 320. Corrective coefficients are available in chapter 1.4.

Technical Data
Detailed technical data includes size, ratio, and other performance metrics.

Specifications and Calculations
The document outlines the calculation of permissible loads on shafts, focusing on radial loads. If loads act at a different point than the protruding shaft, the permissible load should be calculated using the Fry1-2 formula. Values for a, b, and Fr1-2 are from the radial load table. For double-sided output shafts, the load applicable at each end is 2/3 of the table value, provided the loads have the same strength and direction. Otherwise, consultation with the technical office is required.

Radial Load Tables
The tables provide radial load values for various shaft types and sizes, indicating the loads applied at the midpoint of the shaft projection. These values are relevant for gear units operating with a service factor of 1. The tables list input and output shaft specifications, including dimensions and load capacities.

Spare Parts List
The document includes a detailed spare parts list for various models (TA/TF 56B, TA/TF 63B, etc.), specifying bearings, oil seals, and free wheels. It emphasizes the importance of specifying the spare part number, date, article number, and variant number when ordering.

Ordering Instructions
When ordering spare parts, it is crucial to provide the spare part number, date, article number, and variant number, as indicated on the product plate.

Additional Information
The document also includes information on backstop devices and reduction ratios, providing article codes and descriptions for different models.

Sensi di rotazione alberi Nei riduttori esecuzione orizzontale, per ottenere il senso di rotazione contrario al catalogo dell’albero lento mantenendo invariato il senso di rotazione dell’ albero veloce, è sufficiente ruotare il riduttore di 180° attorno all’ asse dell’albero veloce, utilizzando in pratica il piano di fissaggio opposto. Nei riduttori esecuzione verticale è possibile fornire il senso di rotazione contrario al catalogo specificandolo al momento dell’ ordine. Direction of shaft rotation With regard to horizontal mounted gearboxes, in order to get output rotation in a direction opposite...

Tutte le prestazioni dei riduttori sono calcolate in base ad una velocità in entrata di 1400 min-1. Tutti i riduttori ammettono velocità fino a 3000 min-1 anche se è consigliabile, dove l’applicazione lo permette, utilizzare valori inferiori a 1400 min-1. Nella tabella sottostante riportiamo I coefficienti correttivi della potenza in entrata P alle varie velocità riferita ad Fs =1 Input speed All calculations of gear unit performance are based on an input speed of 1400 min-1. All gear units permit speed up to 3000 min-1, nevertheless it is advisable to keep below 1400 min-1, depending on application....
