j. Motor data and additional data:

– When ordering the gearbox and el. motor specify the size, el. motor output and the number of poles, (e.g. 0,75 kW/4p) or a special type of motor.
– Gearbox additional data – e.g. hue, lubricant, stainless design.

Example of type identification:

e) gear ratio i =104.1,
f) horizontal working position (lugs downwards),
g) hollow input shaft for el. motor, size 80,
h) input flange, pitch Ć 130mm (Ć 130/ Ć 110/ Ć 160)
i) basic model without big input flange,
j) 80, 0,75kW/4p – gearbox fitted with a 4-pole, three-phase induction el. motor 0,75 kW, 50 Hz, 230 V / 400VY.

Gearbox selection

Gearbox selections

The following data are necessary to specify proper size of the gearbox: required output torque M₂, gearbox output speed n₂, the way of gearbox loading and the corresponding operating factor S_m. Based on these data suitable size, gearbox performance and gear ratio i can be specified.

Relations for the calculation of individual values

Output torque M_k

Torque M_k is given by the required load of the gearbox. It can be formulated as force F₂, acting in a certain distance on the arm r₂.

M_k [Nm] = F₂ [N] x r₂ [m]

Operating factor S_m

To guarantee working safety with various load and operating conditions the gearbox (motor) type is specified with respect to the operating factor S_m. The table specifies the operating factor S_m values considering the kind of load, average working hours per day and the number of starts per an hour. These values apply to a gearbox driven by a usual motor. When a brake el. motor is used, it is necessary to multiply the operating factor S_m by coefficient 1,15.

Kind of load	Number of starts per hour	Average daily operation [hour]
Kind of load	Number of starts per hour	<2	2÷8	9÷16	17÷24
Normal shock-free operation, small inertia (fans, gear pumps, assembly lines, conveyer screws, liquid mixers, filling machines and wrapping machines)	<10	0,9	1	1,2	1,5
	>10	1	1.1	1.2	1.3
Light jolts at starting, irregular operation, medium inertia (conveyer belts, hoists, winches, kneading-, mixing-, woodworking-, printing- and textile machines)	<10	1,0	1,3	1,5	1,6
	10÷50	1,2	1,4	1,7	1,9
	50÷100	1,3	1,6	2,0	2,1
	100÷200	1,5	1,9	2,3	2,4
Heavy shock irregular operation, high inertia (concrete mixers, suction pumps, compressors, rams, rolling mills, heavy goods conveyer belts, bending machines, presses, nmachines with irregular load and motion)	<10	1,2	1,5	1,8	2,0
	10÷50	1,4	1,7	2,1	2,2
	50÷100	1,6	2,0	2,3	2,5
	100÷200	1,8	2,3	2,7	2,9

When a gearbox is selected, pay care the operating factor S_m to be lower than the gearbox service factor S_f, or increase the required torque M_k acc. to the formula:

M₂ = M_k x S_m

Service factor S_f

The gearbox service factor S_f specifies the ratio between max. torque at the gearbox outlet which can load the gearbox and actual output torque which can be provided by the selected el. motor.

M_2max
S_f = ————————— [-]
M₂

Max. torque M_2max has been specified for the operating factor S_m = 1.
The values of service factors for individual variants of sizes, gears and el. motors are shown in the table 6.1.

El. motor P₁output

The following relation specifies the el. motor P₁ required output:

M₂[Nm] x n₂ [min^-1] x 100
P₁ = ————————————————- [kW]
9590 x η [%]

Radial and axial load of the shaft

At output shaft with cylindrical journal. The values of allowable radial and axial load are shown in the table of max. performances. Allowable load of the shaft is specified for input speed n₁ = 1400 [min^-1].

Radial load F_r

When specifying this value, consider a half length of the shaft free end (see the figure) as the radial force F_r application point.

The calculated F_r shall not exceed max. allowable load specified in the table of max. performances.
If radial force acts at the shaft within a large distance, max. allowable load shall be reduced. For example – only 80 % value shown in the table is allowed for the load at the point of 75 % length of the journal. The allowable load can be higher by 25 % for the load at the point of 30 % of the journal length. If a pulley, sprocket wheel, gear wheel, etc. is fitted on the output shaft, the following formula can specify the radial load:

M₂ x k x 2000
F_r = ——————————– [N]
D

M₂ – output torque [Nm]
D   – design diameter (pitch circle) of a pulley (gear wheel) at the outlet [mm]
k    – load factor
        1,10 sprocket wheels
        1,25 spur wheels
        1,50 pulley

It means that radial load of the shaft can be decreased by increasing the pulley diameter if possible. If the radial load keeps to be high or force acts on the shaft journal in a large distance, external supporting on bearings shall be used in order to absorb these forces.

Axial load F_{a max}

F_r
F_{a max} = ————————— [N]
3

Allowable axial load of a shaft is described by the equation

F_{a max}[N] – max. allowable axial force
F_r[N] – value of allowable radial load according in the table of max. performances

Radial load of shaft with simultaneous acting of axial force

When axial and radial forces act simultaneously, the shaft load shall not exceed

F_ra = F_r – 3 x F_a [N]

F_a[N] – axial load of shaft
F_r[N] – value of allowable radial load specified in the table of max. performances
F_ra[N] – max. allowable radial force with simultaneous acting axial force F_a[N]

Max. values

Max. values of MTC..A gearboxes

The tables show max. values of performances and the corresponding values of output torque which can be transmitted by the gearboxes. These values have been specified for uniform load of the gearbox without jolts – for operating factor S_m = 1 with nominal speed
n₁ = 1400 min^-1.

Lubricants

Gearboxes, MTC..A series, are lubricated by gear bath in oil combined with oil splashing. When performed under normal conditions, it secures proper function, life and performance of the gearbox. Only the position, for which the gearbox has been designed, is permissible with respect to the deaerating plug location. When the operating position is changed, adjust the lubrication quantity for 0–5 gearboxes according to the table. The P2 position cannot be used with gearboxes of sizes 6 and 8. The gearbox shall be arranged at site for this position.

The MTC..A gearboxes are standard delivered with Shell Spirax ASX 75 W-90 oil filling; it is a synthetic oil which under normal conditions provides gearbox operation requiring no maintenance and oil exchange during its life. If a different lubricant is required, e.g. due to more difficult conditions (higher operating temperature, high speed), additives included in the lubricant shall be prevented from attacking the oil packing. Synthetic oils are recommended, they secure longterm life, stability and gear transmission efficiency. When mineral oil filling is used, replacement is necessary after a certain period. When grease is used, it is necessary to consider worse heat removal, lower efficiency, worse lubrication of all components resulting in higher wear. Recommended lubricants are specified in the table called Equivalent Lubricants. Oil quantity for individual types and size of gearboxes is specified in the table called Lubricant Quantity. It is not advised to mix lubricant from various producers. Mixing of synthetic and mineral lubricant is inadmissible.

Standard location of the terminal board is in position 1. Different position shall be specified in the order as a special requirement.

The chapter on el. motors provides basic technical and dimensional data of motors with axis height 56 to 200 delivered by the producer of el. motors – Siemens. As for suplementary or detail technical information ask the producer for separate catalogue of motors.
