Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below. The embodiments of the present invention, and all other embodiments obtained by a person of ordinary skill in the art without any inventive work, belong to the scope of protection of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: the utility model provides a crane main motor car wheelset, includes speed reducer 1, mandrel 2, wheel 3 and

track

4, and 3 framves of wheel are on track 4, and mandrel 2 is installed to the centre of wheel 3, and speed reducer 1 is installed to the one end of mandrel 2, and circular groove 5 has been seted up respectively to the both sides of wheel 3, and the both sides of wheel 3 are equipped with wheel balancing unit, and wheel balancing unit comprises erection column 6, lantern ring 7, first roller bearing 8, mounting groove 9, mount pad 10, threaded rod 11 and second roller bearing 12.

The upper end of the mounting column 6 is welded with a lantern ring 7, the lantern ring 7 is sleeved on the mandrel 2 through a key, a first roller 8 is movably mounted in the middle of the mounting column 6, the first roller 8 is positioned in the circular groove 5, the lower end of the mounting column 6 is provided with a mounting groove 9, a mounting seat 10 is inserted in the mounting groove 9, the upper surface of one end, close to the track 4, of the mounting seat 10 is provided with a second roller 12, the lower end of the mounting column 6 is provided with a threaded rod 11, the threaded part and the thread of the threaded rod 11 are arranged in a threaded hole formed in the mounting seat 10, the lower end of the threaded rod 11 is provided with a rotating ring, thus, the lifting of the mounting base 10 can be controlled by the rotation of the threaded rod 12, so that the second roller 12 on the mounting base 10 is close to the track 4, therefore, the second roller 12 and the first roller 8 can balance the wheel 3, and the serious abrasion and the damage of parts such as an internal bearing and the like caused by uneven load on one side of the wheel 3 are avoided.

The bottom of threaded rod 11 is equipped with anti-rotation structure, anti-rotation structure is by ear piece 15, inserted bar 16, spring 17 and fixture block 18 are constituteed, ear piece 15 welds in the bottom both sides of erection column 6, it has inserted bar 16 to peg graft on ear piece 15, the upper end of inserted bar 16 is seted up screw thread and is installed the nut, it has spring 17 to peg graft in the upper end of inserted bar 16, the lower extreme fixed mounting of inserted bar 16 has fixture block 18, through the rotation of nut like this, can make inserted bar 16 drive the rotatory ring chucking of fixture block 18 with threaded rod 11.
