Description
Technical Field
The utility model belongs to the technical field of auxiliary equipment of tobacco threshing machinery, and particularly relates to an auxiliary tool for disassembling an inner ring of a transmission bearing of a threshing machine.
Background
The threshing and redrying threshing machine uses two discs 6445 single-row tapered roller bearings to be installed in a support as a rotating support piece, after the bearings are damaged, due to the reason that the outer rings of the two discs 6445 single-row tapered roller bearings and the support are installed, the dismounting is difficult, the traditional method can only use copper bars to knock, the phenomenon that the inner rings are inclined is easy to happen due to single-side knocking, the dismounting is difficult, the surface of the inner hole of the support is damaged, and the precision is reduced.
Therefore, it is necessary to provide an auxiliary tool for detaching the inner ring of the transmission bearing of the threshing machine, which can easily detach the inner ring of the transmission bearing of the threshing machine, and can not damage the surface of the inner hole of the support, thereby ensuring the precision of the transmission bearing of the threshing machine.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems that the inner ring of the transmission bearing of the threshing machine is difficult to disassemble and the surface of the inner hole of the support is damaged, so that the precision of the transmission bearing of the threshing machine is reduced, the utility model provides an auxiliary tool for disassembling the inner ring of the transmission bearing of the threshing machine, which can easily disassemble the inner ring of the transmission bearing of the threshing machine, cannot damage the surface of the inner hole of the support and ensures the precision of the transmission bearing of the threshing machine.
In order to realize the purpose, the utility model is realized by the following technical scheme:
the utility model provides an auxiliary tool for disassembling an inner ring of a transmission bearing of a threshing machine, which comprises a middle ejector shaft 1, a split type ejector block 2 and a locking nut 3; well jackshaft 1 be solid cylinder, one end is equipped with the boss, the other end is equipped with the external screw thread, split type kicking block 2 is half-circular arc structure, one end is kicking block head 4, outer along being equipped with the boss, two split type kicking blocks 2 set up in the jackshaft 1, 2 inboard arcs of split type kicking block match with 1 radian of well jackshaft, 1 external screw thread one end of jackshaft in the kicking block head 4 orientation, lock nut 3 matches the installation with 1 external screw thread of well jackshaft, fixes split type kicking block 2.
The utility model has the beneficial effects that:
the inner ring of the transmission bearing of the threshing machine can be easily disassembled, the surface of the inner hole of the support cannot be damaged, and the precision of the transmission bearing of the threshing machine is ensured.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic illustration of an explosive structure of the present invention;
fig. 3 is a schematic view of the installation structure of the present invention.
In the figure, 1-a middle jacking shaft, 2-a split type jacking block, 3-a locking nut, 4-a jacking block head, 5-a bearing inner ring, 6-a drawing claw of a drawing machine and 7-a bearing mounting support.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in fig. 1-3, the auxiliary tool for detaching the inner ring of the transmission bearing of the threshing machine comprises a middle jacking shaft 1, a split type jacking block 2 and a locking nut 3; well jackshaft 1 be solid cylinder, one end is equipped with the boss, the other end is equipped with the external screw thread, split type kicking block 2 is half-circular arc structure, one end is kicking block head 4, outer along being equipped with the boss, two split type kicking blocks 2 set up in the jackshaft 1, 2 inboard arcs of split type kicking block match with 1 radian of well jackshaft, 1 external screw thread one end of jackshaft in the kicking block head 4 orientation, split type kicking block 2 designs into two mutually disconnected split type arc pieces, avoid the unable position that reaches the bearing inner circle 5 that need demolish of kicking block head 4, lock nut 3 matches the installation with 1 external screw thread of well jackshaft, fix split type kicking block 2.
The working process of the utility model is as follows:
during the use, at first put into the centre of two dish bearing inner races 5 with two split type kicking blocks 2, then will take the screwed well apical axis 1 to insert in the middle of two split type kicking blocks 2 to and connect as an organic whole with lock nut 3, use at last and draw the groove on the claw 6 colludes bearing erection support 7 outside face, utilize and draw the machine to draw behind the lead screw that claw 6 middle part was drawn in the machine exerted pressure, drive the inner race and dismantle appurtenance and ejecting with bearing inner race 5, accomplish the dismantlement of threshing machine transmission bearing inner race 5 promptly.
The inner ring 5 of the transmission bearing of the threshing machine can be easily disassembled, the surface of the inner hole of the support cannot be damaged, and the precision of the transmission bearing of the threshing machine is ensured.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the utility model as defined by the appended claims.
