Gear Motor for Charging Station Electric Lock

-
Today, the concept of green energy, energy conservation and emission reduction is deeply rooted in people’s mind. The technological transformation of automobile energy power system has become the focus and core of automobile technology development. As an important part of new energy strategy and smart grid, electric vehicles will definitely occupy an important position in the future automobile industry development.

In practical use, for the purpose of safety, each DC charging gun is equipped with an electric lock (also called electronic lock) to prevent electric vehicles from having live guns drawn while charging. The gear motor for charging station electric lock is a kind of small power micro drive motor, whose main transmission structure is a piece of decelerating transmission equipment assembled by the integrated manufacturing of a driving motor (micro motor) and planetary gearhead (reducer). The driving motor can develop by adopting brush DC motor, BLDC motor, stepper motor, coreless motor and servo motor while the planetary gearhead can adopt satellite gearhead, cylindrical gearhead and worm gearhead as the reducer. The technical parameters of charging station electric lock drive are often customized for development including the output power, voltage, gear ratio, torque, transmission precision, transmission noise, etc.

ZHAOWEI Machinery & Electronics Co., Ltd provides the customized development service of gear motor for charging station electric lock. The customized technical parameters provided by ZHAOWEI are shown below:
Diameter: 3.4mm-38 mm
Voltage: below 24V
Output power: below 50 W
Output speed: 5rpm-1500 rpm
Speed ratio: 2-2000
Output torque: 1gfNaN-50KgNaN


Custom Development Service Case:


Project background: If the new-energy vehicle is equipped with the electric lock, the fee will be recorded once the electric lock locks, preventing the situation that the charging connection fails, but the fee continues to be recorded. After locking, it is unnecessary to manually support the charging gun and the electric lock can be regarded as the contact to record the fee. Once the electric lock is unlocked, the fee will stop to be recorded and the power will be disconnected. Also, the disconnection of electronic lock with precise induction for vehicle systems means the completion of charging, avoiding an electric shock. It contributes to the unattended automatic charging operation after swiping the card while professional personnel are not required.

Solution: ZHAOWEI gear motor scheme for charging station is suitable for the insertion and extraction force test among the plug of new-energy vehicles, locking devices between vehicle sockets and plug-socket connector.
In order to adapt to the compatibility with various charging stations and new energy technology, ZHAOWEI produces different specifications of gear motors (diameter: 3.4mm-45mm; voltage: 1.5V-36V). Moreover, the gear motor scheme can be customized for development according to the needs of charging station manufacturers.

Heat treatment method of planetary reducer

-
Choosing good material of planetary reducer is conducive to improving the bearing capacity and service life of gear reducer. In view of the structural characteristics of precision reducer and the load characteristics of gears, hard tooth face gears should be widely used. There are many heat treatment methods to obtain hard face gear. For example, surface quenching, whole quenching, carburizing quenching and nitriding should be selected according to the characteristics of gear reducer. 1. Surface hardening The common surface quenching methods are high frequency quenching (for small size gears) and flame quenching (for large size gears). When the hardened layer of surface hardening includes the bottom of the tooth root, the effect is the best. The hardness of tooth surface can reach 45-55HRC. 2. Nitriding The application of nitriding can ensure that the gear can achieve high hardness and wear resistance under the condition of minimum deformation. After heat treatment, ...

The DC Gear motor , consisting of a DC electric motor and a gearbox, is at the heart of several electrical and electronic applications. ZHAOWEI have been designing and developing such high quality mini DC gear motors in an easy-to-mount package for a range of products and equipment. Our miniature gear motor work smoothly and efficiently, supporting these electrical and electronic applications. These geared motors have reduction gear trains capable of providing high torque at relatively low shaft speed or revolutions per minute (RPM).  ZHAOWEI DC geared motors reduce the complexity and cost of designing and constructing applications such as industrial equipment, actuators, medical tools, and robotics. ZHAOWEI has engineered a range of planetary and spur gear motors (also known as mini-geared motors and micro-geared motors) suitable for many future and existing applications. The main characteristics of these gear motors are miniature form factors, offering significant strength...

How to solve the wear fault of gear reducer

-
Gear reducers are generally used in low-speed, high-torque transmission equipment, but in fact gear reducers are often used in high-speed mechanical environments, so it is inevitable to withstand multiple types of friction. If not protected, wear failures are likely to occur. Such problems often occur, so we should learn to deal with these wear and tear. There are three kinds of wear faults of the gear reducer. One is the wear of the bearing chamber of the gear reducer, which includes the wear of the bearing housing, the bearing housing of the housing, and the bearing housing of the transmission. The second is the shaft diameter of the gear reducer gear shaft wear, the main wear parts are in the shaft head, keyway and so on. The third is the bearing wear of the gear reducer drive shaft. For the wear failure of the gear reducer, the traditional solution is repairing after repair welding or brush plating, but both have certain drawbacks. Generally, the thermal stress generated by th...
