An electric pull-out bearing ejection device

Abstract

An electric pull-out type bearing ejection device, comprising a permanent magnet synchronous motor, the output shaft of the permanent magnet synchronous motor is connected through a planetary reducer and the power input of a transmission box, the transmission box is fixed on a support frame, the power output of the transmission box and The power input connection of the cylinder body, the power output of the cylinder body and the proximal end connection of the push rod, the cylinder body converts the output rotation of the permanent magnet synchronous motor into the linear motion of the push rod, and the middle part of the push rod matches the inner hole of the bearing on the carrier , a plugboard is installed at the far end of the push rod; move the support frame to a suitable position, tighten it on the carrier, start the permanent magnet synchronous motor, and control the push rod to push out through the planetary reducer, transmission box and cylinder body, and pass through the bearing Insert the inserting plate into the push rod; control the reverse rotation of the permanent magnet synchronous motor, so as to control the push rod to pull back. After the inserting plate contacts the bearing, the bearing will be pushed out gradually with the push rod, and finally the bearing will be disassembled ; The present invention has the advantages of high bearing removal efficiency and small bearing damage.

Description

technical field [0001] The invention belongs to the technical field of bearing dismounting, and in particular relates to an electric drawing type bearing ejection device. Background technique [0002] One of the important contents in mechanical maintenance is the disassembly of bearings. Since the bearings generally adopt interference fit, the fit is tight, and a large force is required to disassemble them. If the removal method is not selected properly, it is easy to cause damage to the bearing. The traditional knocking method is the simplest and crudest bearing disassembly method. With the help of the force of hammering, the parts that cooperate with each other are displaced and separated from each other to realize disassembly. The pull-out method uses a puller to disassemble the bearing. The pull-out method is used to uniformly force the bearing, and the magnitude and direction of the disassembly force are easy to control. This method has a low probability of damaging pa...

Problems solved by technology

[0003] Since some mechanical equipment needs to frequently disassemble the bearing from the carrier during maintenance, the traditional disassembly method is not only inefficient, but may even damage the bearing
