Description

Technical Field

[0001] The present invention relates to the technical field of permanent magnet synchronous motors, and in particular to a high-voltage permanent magnet synchronous variable frequency speed regulating integrated machine. Background Art

[0002] Permanent magnet synchronous motors have become an indispensable part of modern electric drive systems due to their high efficiency, low noise and good control characteristics. With the development of technology, their application scope is constantly expanding; for example, in CNC machine tools, robots and other equipment, they provide high-precision position and speed control; to ensure that permanent magnet synchronous motors can operate safely, stably and efficiently, the following aspects need to be paid attention to during operation. Temperature management and lubrication are a part that cannot be ignored.

[0003] After searching, it is found that the prior art does not pay enough attention to lubrication. The machine cover is often removed to lubricate the internal rotating mechanical parts only during regular maintenance, or lubrication is only considered when obvious wear and tear or harsh sounds occur. Therefore, we propose a lubrication mechanism that can be removed without removal to reduce the difficulty of lubrication, improve production safety, and increase the service life of the device. Summary of the invention

[0004] In view of the technical problem in the prior art that the lubrication of the permanent magnet synchronous motor is inconvenient and parts are easily worn, the present invention adopts the following technical solution:

[0006] By setting up an intermittent oil outlet device and the oil collecting tank semi-enclosing the second bearing, the second bearing can be in contact with the lubricating oil for a long time during use. Even if the maintenance and oiling are forgotten for a long time, the lubricating oil in the oil collecting tank can act on the parts that need lubrication under the vibration of the machine, thereby prolonging the service life of the device.

[0007] A further configuration is that a plurality of spiral ribs distributed in a spiral shape are fixed to the circumferential outer wall of the main body outer frame, and the distance between two adjacent spiral ribs is the same; an auxiliary mounting frame is fixed to the outer wall of the main body outer frame near the mounting plane, and through the arranged spiral ribs, the length of the heat sink can be increased under the same surface area, thereby improving the heat dissipation effect.

[0008] A further configuration is that a plurality of heat dissipation holes 2 are opened on the output end rotary cover near the bearing, and a spring stopper is fixed on the side of the output end rotary cover near the coil winding structure, the spring stopper corresponds to the position of each heat dissipation hole 2 one by one, each of the spring stops is fixed with a reset spring inserted into the heat dissipation hole 2, and a light cover is fixed on the end of the reset spring away from the spring stopper; a heat dissipation fan is fixed on the end of the rotating shaft rod near the rear cover seat; through the provided heat dissipation fan and the light cover tightened by the tension spring, the heat dissipation hole 2 is kept tightly closed when the machine is normally shut down, and once the heat dissipation fan is started and the heat is dissipated, the hot air can be discharged from the heat dissipation hole 2 through the light cover.

[0009] A further configuration is that the middle reserved diameter of the rear cover seat is an annular raised portion whose outer diameter is larger than the outer diameter of the main body frame, and a heat dissipation hole matched with the position of the spiral rib plate is opened on one side of the annular raised portion close to the spiral rib plate.

[0010] A further configuration is that the heat dissipation hole 1 is located near the edge of the spiral rib plate, and a dust cover is provided at one end of the rear cover seat away from the main body outer frame, so that the blown wind can quickly act on the surface of the spiral rib plate, and then quickly take away the heat generated on the surface.

[0011] A further configuration is that a magnet sheet fixing unit is reserved near the middle of the circumferential outer wall of the rotating shaft rod, and the magnet sheet fixing unit includes a plurality of anti-slip slots symmetrically distributed in the center, a permanent magnet plate is inserted in each of the anti-slip slots, and a fastening piece is fixed to one end of the circumferential outer wall of the rotating shaft rod near the heat dissipation fan; by setting up the plug-in fixed permanent magnet plate, the installation and maintenance efficiency is improved, and it is more convenient when the cleaning device needs to be replaced.

[0012] A further configuration is that a through hole is provided at the bottom of the oil collecting trough, and the through hole is matched with the width and thickness of the top end of the A-type support frame, ensuring that the top end of the A-type support frame can be covered until the whole is lower than the bearing clamping hole; the bottom of the oil collecting trough is located on both sides of the through hole and vertical and parallel bearing retaining rings are reserved respectively, and the second bearing is simultaneously clamped in the two bearing retaining rings and the bearing clamping hole; parallel baffles are fixed on both sides of the oil collecting trough; vertical oil leakage grooves are provided on the opposite sides of the two bearing retaining rings; through the provided oil leakage grooves, the lubrication in the oil collecting trough can be concentrated near the second bearing, which is then beneficial to the lubrication operation.

[0013] A further configuration is that a scraper strip is fixed to the top of the A-type support frame; and a vertical permanent magnet is embedded in the top section of the scraper strip; the intermittent oil outlet device includes an oil outlet pipe inserted into the circumferential outer wall of the oil storage tank away from the hinged ear plate, and a sliding bearing is fixed to the circumferential outer wall of the oil outlet pipe near the bottom end, and an oil outlet valve stem is slidably connected in the sliding bearing, and a valve ball and a magnet brush head are fixed to the upper and lower ends of the oil outlet valve stem respectively; a rubber retaining ring matching the shape of the valve ball is fixed to the circumferential inner wall of the oil outlet pipe near the top; a spring retaining ring is fixed to the circumferential outer wall of the oil outlet valve stem between the sliding bearing and the rubber retaining ring, and a reset compression spring is fixed between the top of the spring retaining ring and the lower surface of the rubber retaining ring, and the magnetic poles on the lower surface of the magnet brush head repel the magnetic poles on the upper surface of the permanent magnet.

[0014] With such an arrangement, when the oil storage tank swings as a whole, it will drive the magnetic brush head to intermittently pass over the scraper strip, i.e. the permanent magnet. At this time, it will drive the valve stem to push up, and then push open the valve ball that is blocked by the top outlet of the rubber ring, and oil can leak out for lubrication.

[0015] A further arrangement is that an annular slide rail is fixed to the end of the circumferential inner wall of the rear cover seat near the main body outer frame, and the internal rotation of the annular slide rail is connected to a driven gear ring; a planetary reduction gear set is arranged on the circumferential outer wall of the rotating shaft rod near the annular slide rail, and a rotating rod frame is fixed to the side of the annular slide rail near the side of the oil storage tank, a short shaft rod is rotatably connected in the middle of the rotating rod frame, and a driven rotating wheel and a small gear meshing with the driven gear ring are respectively fixed at both ends of the short shaft rod; a connecting rod is arranged between the surface of the driven rotating wheel near the circumferential edge and the side of the oil storage tank; an oil filling screw tube is inserted into the outer wall of the oil storage tank near the top hinged ear plate, and a balancing air hole is opened near the middle of the outer wall of the oil filling screw tube, and a plug is screwed in the oil filling screw tube; when the oil needs to be drained, the plug only needs to be loosened until the balancing air hole is exposed.

[0016] A further configuration is that bristles are fixed on the lower surface of the magnet brush head, and through the bristles, an oil filling hole is opened on the outer wall of the rear cover seat near the top of the oil filling screw tube, so that the oil accumulated at the bottom of the oil collecting tank can be picked up and applied to the top position of the second bearing.

[0017] The beneficial effects of the present invention are:

[0018] 1. By setting up an intermittent oil discharge device and the oil collecting tank to half surround the second bearing, the second bearing can be in contact with the lubricating oil for a long time during use. Even if the maintenance and oiling are forgotten for a long time, the lubricating oil in the oil collecting tank can act on the parts that need lubrication under the vibration of the machine, thereby prolonging the service life of the device.

[0019] 2. By setting a heat dissipation hole between the ends of two adjacent spiral rib plates, not only can the heat dissipation be accelerated, but also the heat generated by the spiral rib plates can be dissipated in time.

[0020] 3. By setting the oil outlet mechanism at the bottom of the oil storage tank in conjunction with the permanent magnet, when the oil storage tank swings as a whole, it will drive the magnet brush head to intermittently pass over the scraper bar, i.e. the permanent magnet. At this time, it will drive the valve stem to push up, and then push open the valve ball that is blocked by the top outlet of the rubber ring, and then the oil can leak for lubrication.
