Detailed description of the invention

As Fig. 1 is to shown in 7, and conveying worm hanging axis, including connecting shaft 1, hanging axis body 2, logical lid 3 and support bar 6；

Hanging axis body 2 be shaped as annular, the outer wall at hanging axis body 2 extends a projection 21, is provided with first through hole 22, is provided with female thread in one end of the first through hole 22 in projection 21, and the first through hole 22 can be ladder hole；

Lead to lid 3 is shaped as annular, and has two panels, between the logical lid 3 of the held two panels of hanging axis body 2, is provided with a thicker annular groove 32 at logical lid 3 inner ring, is provided with an outside framework oil seal circle 5 in this groove 32；

Being set with a bearing 4 in the middle part of connecting shaft 1, connecting shaft 1 is arranged in hanging axis body 2 and two logical lids 3, and the bearing 4 being sleeved in connecting shaft 1 is positioned in the internal ring of hanging axis body 2, and outside framework oil seal circle 5 banding in logical lid 3 is outside connecting shaft 1；

Being provided with through hole 61 in the middle part of support bar 6, one end of support bar 6 is provided with external screw thread, and support bar 6 is connected on the female thread of projection 21 of hanging axis body 2 by external screw thread, and through hole 61 is connected with the first through hole 22 in projection 21.

By in Fig. 1 it can be seen that the connecting shaft 1 in bearing 4 both sides is by outside framework oil seal circle 5 banding so that bearing 4 and external environment, and then in can effectively preventing the bearing 4 that tiny granulometric impurity enters, prevent bearing 4 from wearing and tearing.

Can be threaded on the outer wall of support bar 6, by this screw thread, on the cross bar 8 support bar 6 can being threaded in conveying worm simultaneously.

Further, between logical lid 3 and hanging axis body 2, pad is placed with a circle graphite grazing pad 8, logical lid 3 can effectively be sealed by graphite grazing pad 8 with hanging axis body 2, prevent tiny granulometric impurity from entering in bearing 4 from the gap between logical lid 3 and hanging axis body 2, and graphite grazing pad 8 has length in service life, resistant to elevated temperatures effect so that this utility model goes for carrying high-temperature material.

Further, being provided with two circle groovings 11 in connecting shaft 1, be respectively clamped into a circlip for shaft 41 in two circle groovings 11, bearing 4 is entrapped between two circlips 41, this structure can effectively prevent bearing 4 from horizontally slipping in connecting shaft 1 so that device operating is more stable.

Further, described hanging axis body 2 is clamped in described in two panels between logical lid 3 by logical lid 3 described in two panels by a coupling part, described coupling part includes polylith the first wing 31 being installed on each logical lid 3 and polylith the second wing 24 being installed on hanging axis body 2, each the first wing 31 and each second wing 24 all offer second through hole 23, it is mounted on for clamping logical lid 3 and the screw and nut of hanging axis body 2 in each second through hole 23, just logical for two panels lid 3 and hanging axis body 2 can be connected into an entirety by screw and nut, when needs are dismantled, only need to unclamp screw and nut the most permissible, and then this utility model dismounting is simple, easy to maintenance.

Further, it is bolted with a butter filler mouth 7 communicated with through hole 61 at support bar 6 away from one end of projection 21, can very easily butter be circulated in bearing 4 by butter filler mouth 7.

Shown in sum up, this utility model uses outside framework oil seal circle 5 to substitute original labyrinth sealing, due to very close to each other between outside framework oil seal circle 5 and connecting shaft 1, in therefore can effectively stopping the middle hanging axis that fine dusts enters, alleviates the dust abrasion to main shaft；The most logical lid 3 and hanging axis body 2 use screw and nut to connect, and when needs are dismantled, only need to unclamp screw and nut the most permissible, and then make this utility model convenient disassembly；Butter can be filled in bearing 4 and outside framework oil seal circle 5 by butter filler mouth 7, after filling butter, lubrication can not only be provided for bearing 4 and connecting shaft 1, and the slight gap between each parts can be sealed up, further improve sealing effectiveness.
