  •       ZHAOWEI Tiny Plastic Gear
      ZHAOWEI Tiny Plastic Gear

      A gear is a toothed wheel designed to transmit force to another gear or toothed component. The teeth of a gear can be shaped to minimize wear, vibration and noise, and to maximize the efficiency of power transmission.

      Gears of differing size are often used in pairs for a mechanical advantage, allowing the torque of the driving gear to produce a larger torque in the driven gear at lower speed, or a smaller torque at higher speed.

      The Advantages of ZHAOWEI tiny plastic gear:

      1. Plastic gears are easily molded into various shapes so they have wider range of configuration.

      2. Plastic gears are less expensive and are lighter in weight.

      3. Plastic gears are chemical and corrosion resistant.

      4. Plastic gears have quieter and smoother operation and offer more efficient drive geometry.

      5. Plastic gears are with inherent self lubricating.

      While plastic gears offer these many advantages over metal gears, their effective use requires proper design and engineering to account for possible dimensional and property variations over the expected range of operating conditions.

  •       Main structure of miniature planetary gearbox
      Main structure of miniature planetary gearbox

      Shenzhen ZHAOWEI Machinery & Electronics Co., Ltd was established in April 1997 which is State High-Tech enterprise for gear transmission design and manufacture. It provides the total drive solution for customers from design, tooling fabrication, components manufacturing and assembly. Then i will introduce main structure of miniature planetary gearbox.

      Micro planetary gearbox is mainly composed of box, gear, bearing and other additional equipment. We all know that each part has its own important work mission. But what exactly does these parts do in tiny planetary gearboxes. ZhaoWei collected some introductions about the main parts in the micro planetary gearbox. Here we learn about them together. The general structure can be divided into three parts as follows:

      1.Box: box is also an important component of high-power gear reducer. It is very important, all parts are installed on the box, all cases should have sufficient strength sealing and stiffness to ensure that the machine is stable and free of oil leakage. Gray cast iron has been used as the material for making box because of its good casting property and vibration absorption property. In order to facilitate the installation and removal of components, the box is mostly made of horizontal partition along the axis line. The upper cover and the lower box are bolted into one body.

      2.Gear, shaft and bearing combination: the most important component of a micro planetary gearbox, consisting of gears of varying sizes and the mutual bite of bearings, which, according to a certain combination, acts as a deceleration and is fixed through shafts to the interior of the box. Gears and shafts, bearings are forged from high hardness and wear resistant materials, this is the core, so the choice of a good gear for more than a decade there will be no quality problems.

      3.Gear box accessories: in order to ensure the normal operation and other functions of the micro planetary gearbox, in addition to giving adequate attention to the structural design of the gears, bearing combinations and case bodies, there must be other accessories. Generally, fans are used to dissipate heat. There are brake emergencies to stop the operation of the mini planetary gearbox and so on, these are the components of gear reducer indispensable.

  •       ZHAOWEI brushless gear motor
      ZHAOWEI brushless gear motor

      Brushless gear motor has some advantages as same as DC brush motor and remove brush and commeuetor to make no mechanical contacts. Magnets are rotate instead of motor coil.
      Semiconductor (hall elements or hall IC) and driver board detect rotor position then changes current to the motor coil to run the brushless motor.
      Technical theory and construction of brushless gear motor.

      Technical theory of brushless gear motor is as same as DC brush motor up to BLI and Law of left hand of Fleming then. The basic characteristics are same but just different rotate magnet or coil.
      Brushless motor is classified two type from the view point of construction, one is inner rotor type (magnet is located inside of coils) which has better mobility and the other is outer rotor (magnet is located outside of coils) which is better to make thinner type motors.It is necessary to choose for each application from both types of brushless motors.

      ZHAOWEI develops many kinds of custom made brushless motors except standard ones.

  •       What are the factors affecting gear life?



      1.Number of gear teeth: too many teeth are not conducive to gear processing, If it have too few teeth, gear teeth meshing times will increase,so it will reduce gear life.
      2.Gear width coefficient: gear width coefficient determines the size of tooth width, and increasing tooth width can improve the bearing capacity, but the larger the tooth width, the more uneven the load distribution along the tooth width. Therefore, a suitable tooth width coefficient should be selected.
      3.Pressure angle: the general standard pressure angle is 20 degrees.If increase the pressure angle.,the bending strength and contact strength of gear will be increased.
      4.Module: for general drive module > 2mm.
      5.Material of gear:
        A.Gear surface should have sufficient hardness and wear resistance to avoid pitting, gluing and plastic deformation as far as possible.
        B.The core of the gear should be of sufficient strength and toughness to withstand the breaking of the gear heel and the impact load.
        C.There should be good processing and heat treatment properties to make it easy to process and improve its mechanical properties.

  •       Common troubles and reasons of micro gear reducer


      As we know,The longer the working time, the more serious the wear of the internal transmission device, and then a variety of troubles appear.The next content are some troubles about micro gear reducers and their reasons.

      1.Abnormal heating of micro gear reducer
      Abnormal heating of the reducer means that the bearing or shell parts of the reducer have a serious heat, which exceeds the normal temperature range. The bearing is heated,which is seen commonly.
      Possible reasons:
      Overloaded operation of reducer;improper assembly of bearings,gears, shafts;bearing wear and so on;short time start and stop too much;too high or too low voltage;poor lubrication,etc.

      2.Abnormal vibration and sound of micro gear reducer
      The meaning is that vibration and sound of micro gear reducer apparently increase and beyond the normal allowable range,or vibration and sound of gear reducer are abnormal.
      Possible reasons:
      Gear and shaft damage;gear meshing part has foreign matter stuck;gear meshing has matter;micro gear reducer and motor coaxiality error is large;fixed not firm;bolt loose;lubricating oil is not clean and impurity,etc.

      3.Oil leak
      Mainly the position of the bearing end cover of the speed reducer , the sealing surface or the combination surface of the casing and other parts have lubricating oil leakage .
      Possible reasons:
      Poor sealing, box deformation, shell damage and so on;it may also be in the gear transmission,friction heat,resulting in oil temperature rise,oil thinning and easy to leak.

  •       How to calculate transmission ratio?


      1. i=n1/n2=D2/D1 ,i=n1/n2=z2/z1.
      i represents transmission ratio or gear ratio
      n1 represents the speed of drive gear
      n2 represents the speed of driven gear
      D2 represents the diameter of driven gear
      D1 represents the diameter of driving gear
      Z2 represents the tooth number of driven gear
      Z1 represents the tooth number of driving gear

      2.Multistage gear transmission : the transmission ratio between each two shafts is calculated according to the above formula 2: the total transmission ratio from the first axis to the n-axis is calculated according to the following formula: total transmission ratio = (Z2/Z1)×(Z4/Z3)×(Z6/Z5) = (n1/n2)×(n3/n4)×(n5/n6).
