Abstract
The utility model relates to a rotor bearing dismantles frock, including a centre gripping section of thick bamboo, locking bolt and ejector pin, a centre gripping section of thick bamboo is cylindricly, a centre gripping section of thick bamboo center has been link up along the axial and has been seted up the ejector pin hole, the ejector pin sets up downthehole and can the downthehole precession of ejector pin is unscrewed, a centre gripping section of thick bamboo one end has been seted up the bearing and has been placed the counter bore side and has been seted up the locking bolt hole, the locking bolt sets up downthehole and can the downthehole precession of locking bolt is unscrewed to locking or loosening waits to dismantle the bearing, this rotor bearing dismantles frock, and it is convenient to dismantle, suitable for the occasion extensively, the commonality is strong, need.
Description
The technical field is as follows:
the utility model relates to a motor assembly fixture technical field especially relates to a rotor bearing dismantles frock.
Background art:
at electric motor rotor's axle head, all can be connected with the bearing usually, for guaranteeing bearing operating stability, the cooperation of bearing and rotor axle head is interference fit usually, and the bearing size is less usually, and this has brought certain difficulty to the dismantlement of bearing.
The existing rotor bearing dismounting mode is large in limitation, when the distance between the bearing and the rotor is very close, the tool is not inserted in enough space, and dismounting is very complicated.
The utility model has the following contents:
the utility model aims at the defect to prior art, provide a dismantle convenient, the wide, the strong rotor bearing of applicable occasion dismantles frock.
The utility model discloses a realize through following technical scheme:
the utility model provides a frock is dismantled to rotor bearing, for the dismantlement of bearing when realizing not having the frock space of dismantling between rotor and bearing, this frock is dismantled to rotor bearing includes a centre gripping section of thick bamboo, locking bolt and ejector pin.
A centre gripping section of thick bamboo is cylindricly, a centre gripping section of thick bamboo center has link up along the axial has seted up the ejector pin hole, the ejector pin sets up the ejector pin is downthehole and can the downthehole precession screw-out of ejector pin to ejecting rotor shaft, a centre gripping section of thick bamboo one end has been seted up the bearing and has been placed the counter bore, be used for location and clamping to treat to dismantle the bearing, the bearing is placed the counter bore side and has been seted up the locking bolt hole, the locking bolt sets up the locking bolt is downthehole and can the downthehole precession screw-out of locking bolt to locking or loosening treat to dismantle the bearing, because adopt the locking bolt structure, the bearing is placed the counter bore and.
In order to save more labor and improve the disassembly convenience, one end of the ejector rod, which is far away from the clamping cylinder, is provided with a rotating handle.
The utility model has the advantages that: according to the rotor bearing dismounting tool, the bearing clamping barrel with the spiral ejector rod is designed, so that the bearing is dismounted when no dismounting tool space exists between the rotor and the bearing, and the convenience of dismounting the rotor bearing is greatly improved; the locking bolt structure matched with the counter bore is placed through the designed bearing, the clamping and the dismounting of rotor bearings of various sizes are realized, the universality of the tool is improved, and the tool is dismounted by the rotor bearings, and the structure is simple, convenient and labor-saving.
Drawings
Fig. 1 is the utility model discloses a rotor bearing dismantles frock's schematic structure view.
The specific implementation mode is as follows:
the following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be clearly and clearly defined. In the present invention, directional terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc. refer to directions of the attached drawings only. Accordingly, the directional terms used are used for describing and understanding the present invention, and are not used for limiting the present invention.
As shown in fig. 1, a rotor bearing dismantles frock, including a centre gripping section of thick bamboo 1, locking bolt 2 and ejector pin 3, a centre gripping section of thick bamboo 1 is cylindricly, a centre gripping section of thick bamboo 1 center has link up along the axial and has seted up ejector pin hole 11, ejector pin 3 is kept away from a centre gripping section of thick bamboo 1 one end is equipped with twist grip 4, ejector pin 3 sets up in the ejector pin hole 11, through rotating twist grip 4, the ejector pin can the interior precession of ejector pin hole 11 is unscrewed, a centre gripping section of thick bamboo 1 one end has been seted up the bearing and has been placed counter bore 12, the bearing is placed counter bore 12 side and has been seted up locking bolt hole 13, locking bolt 2 sets up in locking bolt hole 13 and can the precession is unscrewed in locking bolt.
When the tool for disassembling the rotor bearing is used for disassembling the bearing on the shaft end of the rotor, the bearing on the clamping cylinder 1 is firstly used for placing the counter bore 12 to sleeve the bearing to be disassembled, then the locking bolt 2 is rotated to lock the bearing to be disassembled, and finally the rotating handle 4 on the ejector rod 3 is rotated to drive the ejector rod 3 to move towards the bearing to be disassembled, gradually prop against the rotor shaft, further rotate the rotating handle 4, eject the rotor shaft and the rotor assembly, thereby completing the disassembly of the bearing.
The above-mentioned embodiments only represent one embodiment of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
