  •       Correct methods of maintaining brushless dc gear motor
      Correct methods of maintaining brushless dc gear motor

      This paper briefly introduces the maintenance method of brushless DC gear motor.

      (1)Before disassembly, with compressed air blow off the motor surface dust,and wipe the surface dirt thoroughly.
      (2)Selection of workplace for motor break-up,clean up the environment at the scene.
      (3)Be familiar with the structure features and technical maintenance requirements.
      (4) Ready to collapse the required tools and equipment (including special tools).
      (5)In order to further understand the defects in motor operation, made a check test before disassembly. For this reason, test the motor at rate load, checking the temperature, sound and vibration of each part of the motor in detail, and testing the voltage, current, rotational speed, etc., then disconnect the load, and do a single no-load inspection test. Measure the no-load current and no-load loss and make a record.
      (6)Cut off the power supply, demolish deceleration motor wiring and record.
      (7)The absorption ratio K.When the absorption ratio is greater than 1.33, it shows that the insulation of the motor is not dampened or the degree of dampness is not serious. In order to compare with previous data, at any temperature must also be converted to the same temperature,then measure the absorption ratio.

      Shenzhen ZHAOWEI Machinery &Electronics Co.,Ltd was established in April 1997 which is State High-Tech enterprise for gear transmission design and manufacturing.It provide the total drive solution for customers from design,tooling fabrication,components manufacturing and assembly.We mainly engaged in micro gear motor,planetary gear box,brushless dc gear motor,and other products.Meanwhile we can customize as requirement.

  •       Various possible factors affecting the cleanliness of micro gearbox and its harm
      Various possible factors affecting the cleanliness of gearbox and its harm
      Various possible factors affecting the cleanliness of gearbox and its harm.

      (1)The poor cleanliness of the lubricating oil used is a direct cause of poor cleanliness. When the gearbox starts running, the lubricating oil enters the lubricating line and distributes to the lubrication points (usually the gear meshing area and bearing area), meanwhile the impurities also reach the gearbox area and the bearing, thus affecting their service life.

      (2)The iron chips produced when the parts are machined have not been cleaned up. On the one hand, when the next working procedure is added, the defects such as pits or scratches on the surface of the parts are caused by carelessness not cleaning up the iron chips of the parts. On the other hand, iron scraps in some positions are not easy to be cleaned, such as iron chips in oil holes, which will be brought into the working area by lubricating oil in the gearbox, thus causing damage to the parts.

      (3)After pickling, the oil route will be welded and other processing.In fact,no further welding is allowed after pickling, otherwise the impurities from the welding will enter the pipeline and enter the gearbox with the circulation of lubricating oil.

      (4)Processing some parts on the assembled finished product. Reasons for the same

      (5)Spare parts after cleaning do not preserve well, placed at will. Such as dust and other impurities cover the important surface of the part, affecting the size of the match.

      (6)The sealing effect is poor. In terms of design, v-type dust-proof sealing ring can be used on the input and output shaft, and the surface roughness of the shaft can be improved by processing.

      (7)Paint cannot withstand high temperature. When the gearbox is running at high temperature, the inner wall of the case cannot withstand the high temperature,so the paint desquamate falls into the lubricating oil, and the outer wall of the box affects the appearance of the paint.

      (8)The sealant fell into the box. When too much sealant is applied on the face of the gear box or other joint, the sealant will squeeze into the box and enter the lubricating oil after closing the box or closing the cover.

  •       How to disassemble a micro planetary gearbox?
      How to disassemble a micro planetary gearbox?

      Step1.Unscrew the oil screw plug and drain the oil in the micro planetary gearbox.

      Step2.Unscrew the fastening screw of the gearbox cover and lift the cover plate,Then screw down the fastening screw of the pulley and take the pulley down.

      Step3.The disassembly order of each axis and related parts is: disassemble from one axis, two axis to three axis in turn, put it in order when disassembling, do not mess up, lest misfit cause accident.

      1.Disassembly of one-axis and related parts:Unscrew the bearing cover at both ends of the shaft, screw in the disassembly hole of the two bearing cover respectively with four screws, lift the bearing seat from the box body, let it loose, and remove the two bearing covers. Then remove the gear ring and then remove the shaft and the upper gear from the box (because the shaft is connected to the gear).

      2.Disassembly of two-shaft and related parts:Unscrew bearing cap screw at both ends of shaft and remove gear ring at both ends. Then the box is set sideways and the outer edge of the bearing seat hole on one side of the two-axis pinion is pressed with a circular sleeve, and the shaft is gently knocked out. Remember not to press hard to avoid damage shaft neck, gear or box. Because the gear is mounted on the shaft, it should be removed from the box cover window.

      3.Disassembly of three-axis and related parts: same as two-axis disassembly method. But the triaxial shaft should be removed from the end of the shaft neck where the drive wheel is mounted, otherwise it will not come out.
