how do you measure the root clearance between a girth gear and a pinion of a grinding ball mill and what is the recommended root clearance. this ball mill uses helical gears(i.e. 284 teeth girth gear with a 24 teeth pinion).
therefore, the ball mill gear and pinion materials are required to have sufficient strength, high wear resistance and good processing performance. when manufacturing ball mill girth gear: 1. chaeng arranges lineation process several times to ensure the machining accuracy and position accuracy of girth gear. 2.
1. detection of ball mill girth gear. after the girth gear is installed, its radial runout and end face runout should be detected. the radial runout f is based on the gear axis and has a value equal to the algebraic difference between the maximum and minimum values of the radial deviation.

Girth gear is an important transmission part of rotary kiln and ball mill equipment. the motor drives the pinion and pinion drives the girth gear mounted on the cylinder shell, because of this, the ball mill start driving. the girth gear is connected to the cylinder shell by bolt.
Girth gear is to be fitted to the mill body in the same position with respect to radial run-out, as it had for finish tooth cutting on the machine. in practice this is not usually attainable. after instal- lation, the teeth of a girth gear of 7.5 diameter, for example, can be expected to have a .
Girth gears (gear wheels) are large ring gears which are normally fitted to the outside of ball mills or rotary kilns to provide the primary rotational drive,which is required to be operated in a long time so, the quality requirements during the actual production for the big gear ring are very high girth gears are applied in the mining, cement, minerals industries used in various types of .
Goirid tuairisgeul: gear ring weight: 10~35t applicable devices: rotary kiln, ball mill, tube mill application: cement, building material, metallurgy etc. customizable or not: yes product introduction gear ring is the main part of rotary kiln and ball mill which has to run for a long time, therefore, there is high quality requirement for gear ring in production.
High efficiency level as no coupling required on the mill side; the choice is yours. girth gear and pinion drives are sufficient for up to 4,500kw. our integral drive is suitable for up to 6,500kw. for mills with a drive power of between 5,000 and 10,000kw, we recommend a classic central drive with fixed planetary gears.

the girth gear(big ring gear) and pinion are the key of the edge transmission device. their reliable operation is directly related to the stable production of the mill. in order to ensure their reliable operation, in addition to strengthening the daily maintenance and regular maintenance, the installation and alignment of the girth gear and pinion are also important.
gears (girth gear and pinions - double drive) are new and from other manufacturer. compared with the previous gears on this mill, new gears have a larger modulus and different number of the teeth but with the similar gearmesh - now 61.8hz instead of 57hz before.
Large girth gears are installed around the cylinder to rotate the horizontal ball mill cylinders. a pinion connects these directly to the industrial gear unit. sew-eurodrive does not just provide industrial gear units, we provide the complete drive package with specially segmented girth gears.
