Technical Field

The utility model relates to a monitoring technology of mechanical parts, in particular to a bearing monitoring device.

Background

The rolling bearing is one of the most common parts in mechanical equipment, and the operation state of the rolling bearing is related to the safety, reliability and maintainability of a mechanical transmission system and the operation of the whole machine. The bearing is in failure, the efficiency of the system can be reduced, the shutdown is caused, the accident is serious, the economic loss is caused, and even the casualties are caused. Because the bearing has bad working conditions and higher failure probability, the early warning of the early failure of the bearing is realized by monitoring the real-time state of the bearing, and the early warning has social and economic benefits.

With the rise of intelligent diagnosis technology and the development of sensors for mechanical equipment, the concept of intelligent bearings is also proposed. The intelligent bearing is typically formed by integrating sensing devices with different purposes on the basis of a traditional bearing, combining the sensing devices into a whole to form a unique structural unit (referred to as a bearing monitoring module for short), and processing information through a microcomputer to achieve the purpose of real-time online monitoring.

The automobile axle is connected with the frame through the suspension, and wheels are arranged at two ends of the automobile axle. The axle is used for bearing the load of the automobile and maintaining the normal running of the automobile on the road. Wheel hubs are arranged at two ends of the axle, the wheel hubs are connected with the axle body through bearings, and wheels are mounted on the wheel hubs. Monitoring this bearing requires mounting a bearing monitoring module on the hub. If adopt the battery to supply power to bearing monitoring module, although simple to operate, battery life can't satisfy the requirement of long-term monitoring and need change the battery, can not realize continuous monitoring.

SUMMERY OF THE UTILITY MODEL

The technical problems solved by the utility model are as follows: how to enable the bearing monitoring module to continuously monitor the automobile axle bearing.

In order to solve the technical problems, the utility model provides the following technical scheme: the bearing monitoring device with inductive power supply comprises a bearing monitoring module and an inductive power supply module, wherein the inductive power supply module comprises an electromagnetic induction head and a coil, the bearing monitoring module and the coil are positioned on a wheel hub, and the electromagnetic induction head is positioned on an axle body; the bearing monitoring module is installed on the tool, the tool is in an annular shape and wraps on the hub, and the coil wraps on the hub and is close to the tool.

The axle body is connected with the automobile body and keeps static in the running process of the automobile, the wheel hub rotates relative to the axle body, the coil on the wheel hub rotates relative to the electromagnetic induction head, the magnetic flux from the electromagnetic induction head changes in the coil, and the coil generates electricity to supply power to the bearing monitoring module.

The bearing monitoring module runs normally due to the power supply of the coil, monitors vibration and temperature, and provides signals to an external main control unit in a wireless communication mode.

A frock for installing bearing monitoring module is the annular form, wraps on wheel hub, makes things convenient for bearing monitoring module to set up on wheel hub. Moreover, the bearing monitoring module can be arranged on the inner wall of the tool, and the tool provides protection for the bearing monitoring module; and the frock can wrap up the coil, fixes and protects the coil.

The utility model can realize that the bearing monitoring module can continuously monitor the automobile axle bearing and can effectively maintain the continuous monitoring.

Detailed Description

With reference to fig. 1 and 2, the inductively powered bearing monitoring device includes a bearing monitoring module (not shown in the drawings) and an inductively powered module, where the inductively powered module includes an electromagnetic induction head 10 and a coil (not shown in the drawings), the bearing monitoring module and the coil are located on a hub 20, and the electromagnetic induction head is located on an axle body 30; bearing monitoring module installs on frock 40, and the frock is the annular form, wraps on wheel hub, and the coil winding is on wheel hub and be close the frock.

The axle body 30 is connected with the automobile body and keeps static during the running of the automobile, the wheel and the hub 20 rotate relative to the axle body, the coil on the hub rotates relative to the electromagnetic induction head, the magnetic flux in the coil changes, the coil induces electricity, the bearing monitoring module connected with the coil is electrified, and the automobile can normally run.

The bearing monitoring module comprises a shell, a PCB and a battery, wherein the PCB and the battery are arranged in the shell, the shell is provided with a mounting pin, and the mounting pin can be fixedly connected with the tool 40. The PCB is integrated with a sensing device and a wireless communication device, the sensing device comprises a sensor for monitoring vibration and a sensor for monitoring temperature, the sensor is used for monitoring vibration and temperature of the bearing, and the wireless communication device transmits signals monitored by the sensing device to an external main control unit.
