Summary of Contents for Siemens MOTOX BA 2510

  • Page 3 WARNING Siemens products may only be used for the applications described in the catalog and in the relevant technical documentation. If products and components from other manufacturers are used, these must be recommended or approved by Siemens. Proper transport, storage, installation, assembly, commissioning, operation and maintenance are required to ensure that the products operate safely and without any problems.
  • Page 4 The described gearboxes correspond to the state-of-the-art at the time these operating instructions were printed. Siemens AG reserves the right to change individual components and accessory parts in the interest of further development. The changes serve to improve the performance and safety. The significant features are retained. The operating instructions are updated regularly with new contents.

  • Page 5: Intended Use

    The copyright to these operating instructions is held by Siemens AG. These operating instructions must not be wholly or partly reproduced for competitive purposes, used in any unauthorized way or made available to third parties without agreement of Siemens AG. Intended use ATEX version gearboxes The ATEX gearbox satisfies the requirements of the Explosion Protection Directive 2014/34/EU.

  • Page 6: Particular Types Of Hazards

    Replace damaged bolts with new bolts of the same type and strength class. Siemens AG accepts the warranty only for original spare parts. The manufacturer who installs the geared motors in a plant must include the regulations contained in the operating instructions in its own operating instructions.

    WARNING Risk of explosion when working with solvents Ensure adequate ventilation. Do not smoke! WARNING Risk of eye injury Rotating parts can throw off small foreign particles such as sand or dust. Wear protective eyewear! In addition to the prescribed personal protection gear, also wear suitable protective gloves and safety glasses. Agitator flange For helical gearbox DR/ZR sizes 68 to 168 Technical description...
  • Page 8 Lubrication In normal operating conditions and with low loads, the lubrication of the bearings is sufficient for approximately 25,000 to 30,000 operating hours. For higher loads due to speed and / or temperature, schedule regreasing at shorter intervals. 2.2.1 Regreasing intervals The regreasing interval is valid for a temperature of +70 °C, measured on the surface of the housing in the vicinity of the bearing.
  • Page 9 Maintenance of the output-side bearing in the agitator flange Note Change the grease filling of the roller bearing when you change the gearbox oil. For refilling, use lithium-saponified roller bearing grease NLGI 3/2. Procedure 1. Dismantle the output-side bearing unit. 2.
  • Page 10 The bevel helical gearbox and the parallel shaft gearbox can be supplied with an upstream mixer flange. With an upstream locating bearing, the bearing system is suitable for high external forces. The absorbed radial and axial loads are transmitted to the machine via the mixer flange. The bearings in the mixer flange are lubricated independently of their design.

    CAUTION Sharp-edged parts in the sealing area destroy the seal's coating The flushing medium must not damage the slide ring seal. The slide ring seal is designed according to DIN 24960. It is independent of the direction of rotation and is not balanced. The slide ring seal is particularly suitable for media containing solids, such as waste water.
