Abstract

The invention discloses a bearing body with an auxiliary bearing disassembling function. The bearing body is composed of a bearing pedestal shell, a bearing mounted in the bearing pedestal shell, an upper end cover and a lower end cover, wherein the upper end cover and the lower end cover are fixed to the upper end opening position and the lower end opening position of the bearing pedestal shell through connecting bolts. An upper oil seal and a lower oil seal are arranged on the inner ring face of the upper end cover and the inner ring face of the lower end cover respectively. A thrust ring is arranged in the position, located between the bearing and the upper end cover, inside the bearing pedestal shell. A convex ring table which extends downwards is arranged on the face, making contact with the thrust ring, of the upper end cover, and the convex ring table stretches into the thrust ring. A plurality of screw holes are evenly distributed in the circumferential direction of the upper end cover, positioning bolts are connected in the screw holes in a threaded mode, and the lower ends of the positioning bolts stretch into a positioning groove formed in the thrust ring. The nominal diameter of the positioning bolts is equal to the nominal diameter of the connecting bolts, and the screw pitch of the positioning bolts is equal to the screw pitch of the connecting bolts. The bearing body with the auxiliary bearing disassembling function has the advantages that bearing disassembling and assembling work can be completed without a press machine or specially-used bearing disassembling and assembling equipment; besides, pressure is stable in the assembling and disassembling process of the bearing, and the disassembling and assembling quality of the bearing is guaranteed.

Description

Possesses the bearing support of auxiliary bearing disassembling function

Technical field

The present invention relates to bearing support, especially relate to the bearing support possessing auxiliary bearing disassembling function.

Background technique

For large-scale bearing support, as the bearing support on Flour production equipment square plansifter, when overhauling, the dismounting of bearing and installation are a great problems.Because the size of bearing support is comparatively large, bearing takes apart and overhauls rear installation and enters in bearing support, all needs special press machine to operate.But use producer not often to be equipped with the press machine removing and installing bearing, this just give use the device maintenance of large size bearing body but come inconvenient.Therefore, the mode using producer often to adopt weight to knock is dismantled and installs bearing, and which not only requires higher to the technical merit of operator, and can not ensure the installation quality of bearing, and the safe handling for equipment leaves certain hidden danger.

Summary of the invention

The object of the invention is to provide a kind of bearing support possessing auxiliary bearing disassembling function.

For achieving the above object, the present invention takes following technical proposals:

The bearing support possessing auxiliary bearing disassembling function of the present invention, the bearing comprising bearing support housing and install in it; Upper end cap and the lower end cap composition of the described upper and lower port of bearing support housing is fixed on by connecting bolt; Upper and lower oil sealing is respectively arranged with at the inner ring surface of described upper and lower end cap; In bearing support housing, be provided with Thrust ring between described bearing and upper end cap, the surface of contact of upper end cap and described Thrust ring is provided with the bulge loop platform to downward-extension, and described bulge loop platform extends in Thrust ring; Circumferentially uniformly on upper end cap offer multiple screw, be all bolted with holding down bolt in described multiple screw, described holding down bolt lower end extends in the locating slot that is opened on Thrust ring; The nominal diameter of described holding down bolt and described connecting bolt and pitch are all equal.

Described upper end cap and lower end cap are respectively by upper bolt and lower bolt and described bearing support housing bolt; The end of described lower bolt extends upwardly to the isometry position of described Thrust ring.

The invention has the advantages that and do not need press machine or special bearing disassemblerassembler, bearing disassemble or assemble work can be completed, and the cargo handling process pressure of bearing is steady, ensure that the dismounting quality of bearing.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Embodiment

As shown in Figure 1, the bearing support possessing auxiliary bearing disassembling function of the present invention, the bearing 2 comprising bearing support housing 1 and install in it; The upper end cap 3 of the upper and lower port of bearing support housing 1 is fixed on and lower end cap 4 forms by connecting bolt; Upper end cap 3 and lower end cap 4 are respectively by upper bolt 5 and lower bolt 6 and bearing support housing 1 bolt; Upper and lower oil sealing 7,8 is respectively arranged with at the inner ring surface of upper and lower end cap 3,4; In bearing support housing 1, between bearing 2 and upper end cap 3, gap is provided with Thrust ring 9, and upper end cap 3 is provided with the bulge loop platform 10 to downward-extension with the surface of contact of Thrust ring 9, and bulge loop platform 10 extends in Thrust ring 9; Circumferentially uniformly on upper end cap 3 offer multiple screw, be all bolted with holding down bolt 11 in each screw, holding down bolt 11 lower end extends in the locating slot that is opened on Thrust ring 9, with limit thrust ring 9 along the circumferential direction displacement; Nominal diameter and the pitch of holding down bolt 11 and upper and lower threaded screw fasteners 5,6 are all equal; The end of lower bolt 6 extends upwardly to the isometry position place of Thrust ring 9.

The present invention's dismounting and bearings mounted process are summarized as follows:

When needs dismounting bearing 2, first all lower bolts 6 are laid down, lay down lower end cap 4, make bearing 2 lower end be free state, then lay down all holding down bolts 11, lower bolt 6 is arranged in the screw of holding down bolt 11, and make the front end of lower bolt 6 be absorbed in the locating slot on Thrust ring 9, tighten lower bolt 6 successively gradually, lower bolt 6 pushes Thrust ring 9 gradually and bearing 2 is released bearing support housing 1 downwards, completes the dismounting of bearing 2.When bearing 2 installed by needs, first holding down bolt 11 is arranged on upper end cap 3, and by upper end cap 3, Thrust ring 9 and bearing 2 sequentially coaxially stack to bearing support housing 1 inner orifice along place, should ensure when stacking that holding down bolt 11 lower end is absorbed in the locating slot on Thrust ring 9, then upper end cap 3 and bearing support housing 1 is connected with lower bolt 6 by the installation screw of upper end cap 3, tighten stay bolt gradually successively, bearing 2 is pressed downward to bearing support housing 1 gradually, when upper end cap 3 is about to be in place, pull down lower bolt 6 to be replaced by bolt 5 upper end cap 3 is in place, lower bolt 6 is used to be installed on bearing support housing 1 by lower end cap 4, bearing 2 installation.
