Description

Roots blower embedded type bearing inner and outer ring puller

Technical Field

The utility model relates to an embedded bearing inner and outer ring puller of a Roots blower.

Background

The desulfurization system of the Xinjiang eight-iron and steel stock energy center thermal power branch factory mainly is used for providing disturbance wind for the desulfurization system, and is used for disturbing ash in an ash warehouse, wherein the ash warehouse is provided with a dry ash discharging and wet ash discharging opening, and the disturbance wind is used for enabling ash to be discharged more smoothly and not to be agglomerated. The ash warehouse fluidization fans used by the energy center thermal power distribution factory desulfurization system are all roots fans, the front end bearing and the rear end bearing of each roots fan are embedded bearings, when the new bearings are damaged and need to be replaced, the old bearings need to be detached and then installed, the embedded bearings are adopted, the original method is that pull rods are welded on the inner rings or the outer rings of the bearings to pull the bearings out, but the common pull rods are 20# steel, different from the high-carbon steel materials of the bearings, the welding performance is poor, and the bearings are easy to break from welding parts. The embedded bearing inner and outer ring puller is needed to be manufactured, so that the old bearing can be conveniently detached.

Disclosure of Invention

The utility model aims to provide a Roots blower embedded type bearing inner and outer ring puller which is manufactured according to the size and shape of the inner and outer rings of a bearing to pull Ma Kazhao, so that the inner and outer rings of the bearing are clamped, and the bearing can be conveniently pulled out directly.

The technical scheme includes that the embedded bearing inner and outer ring puller of the Roots blower comprises a puller disc and a hexagon head with a thimble rotating, three sliding grooves are symmetrically and uniformly distributed on the radial disc body of the puller disc in a central mode, a pull Ma Kazhao pull rod is respectively arranged in each sliding groove, the pull Ma Kazhao pull rod moves outwards or inwards along the sliding grooves to adapt to different working sizes, the pull Ma Kazhao pull rod is parallel to the hexagon head, arc clamping jaws are respectively arranged at the inner side ends of the pull Ma Kazhao pull rods in a threaded connection mode, the plane width of the clamping jaws is 15mm, the length of the arc surface is 30mm, and the thickness of the clamping jaws is 10mm.

And arc pull Ma Kazhao is manufactured according to the size and shape of the inner ring and the outer ring of the bearing, and the two ends of the manufactured claw are arc, so that the inner ring and the outer ring of the bearing can be clamped conveniently. The other two surfaces are plane surfaces and are narrower, so that the clamping jaw can be conveniently placed in the gap between the inner ring and the outer ring. After the clamping jaw is placed in the gap between the inner ring and the outer ring, the clamping jaw is rotated, so that the clamping jaw is attached to the inner ring and the outer ring of the bearing. The on-site Roots blower uses a deep groove ball bearing 6316, the jaw plane width is 15mm, the arc surface length is 30mm, and the jaw thickness is 10mm. The pull rod Ma Kazhao is internally threaded and externally threaded for threadably connecting the jaws to the pull rod Ma Lagan. After the pull Ma Kazhao is clamped on the inner ring and the outer ring of the bearing, the pull rod is connected with the clamping jaw, the thimble is tightened, and the bearing is pulled out by adopting a pulling method. The utility model greatly improves the maintenance efficiency, reduces the labor intensity, and has long disassembly time and high working intensity by adopting the welding pull rod for drawing. Other parts of the equipment are effectively protected from being damaged, and the bearing shell and the rotating shaft can be damaged by the original welding and dismounting method. The practicality is strong, has been used in the dismantlement work of the embedded bearing of roots fan of energy center heating power branch factory at present, and the result of use is showing.

fig. 2 is a working state diagram of the present utility model.

Description of the embodiments

The utility model provides a roots blower buries outer lane and draws horse in formula bearing, includes draw horse dish 3 and a thimble 7 pivoted hexagon head 4, and the hexagon head passes through screw fixed connection and installs in draw horse dish 3 center department. Three sliding grooves 2 are uniformly distributed on the radial disc body of the sliding disc 3 in a central symmetry mode, a pull Ma Kazhao pull rod 5 is respectively arranged in each sliding groove 2, the pull Ma Kazhao pull rod 5 moves outwards or inwards along the sliding grooves 2 to adapt to different working sizes, the pull Ma Kazhao pull rod is parallel to the hexagon head 4, the inner side ends of the pull Ma Kazhao pull rods are respectively provided with arc-shaped clamping claws 1 in a threaded connection mode, the plane width of each clamping claw 1 is 15mm, the length of each arc-shaped surface is 30mm, and the thickness of each clamping claw is 10mm.

When the bearing box is in operation, the bearing is arranged in the bearing box shell, after the pull Ma Kazhao 1 is clamped between the inner ring and the outer ring 9 and 11 of the bearing, the pull rod is connected with the clamping jaw, the central shaft 8 is tightly propped by the tightening thimble 7, and the bearing 10 is pulled out by adopting a drawing method.
