Description

Novel bottom bearing

Technical Field

The utility model relates to a bottom bearing technical field specifically is a novel bottom bearing.

Background

The bearing is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and guarantee its rotation precision, and the bottom bearing is also called bottom support, is one of slide bearings. For a stirring device designed by a top-mounted simple beam, the stirring device is generally arranged at the lowest end of a stirring shaft and is mainly used for limiting the swinging of the stirring shaft, a bottom bearing device is widely applied to stirring equipment in the industries of chemical industry, food, pharmacy, environmental protection and the like, particularly the stirring device is applied to equipment which cannot adopt a middle bearing and has a long stirring shaft and a high rotating speed, the service life of the bottom bearing is limited by medium conditions and materials, the bottom bearing is generally short, and the stirring device needs to be replaced periodically,

However, the bottom bearings in most of stirring devices in the market are single in functionality and inconvenient to use, the traditional bottom bearings are installed and maintained in a reaction kettle or a stirring tank, and the installation space is limited, so that people cannot conveniently enter the kettle to operate.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel end bearing to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel end bearing, includes the agitator tank, agitator tank bottom is close to axle center department fixed mounting has a supporting seat, there is the axle sleeve inside being close to axle center department through bolt fixed mounting of supporting seat, the axle sleeve upper end runs through the supporting seat and extends to inside the agitator tank, the axle head is installed in the inside rotation of axle sleeve, spindle head fixed connection is in the (mixing) shaft bottom, the supporting seat extends to the agitator tank outside and covers with the axle sleeve bottom and has the bearing box, the bearing box bottom is close to axle center department fixed mounting and has the drain.

Preferably, a bearing bush is embedded between the shaft sleeve and the supporting seat.

Preferably, the bearing box and the supporting seat are connected and sealed through bolts.

Preferably, the supporting seat is formed by one-time processing of a die.

Preferably, the shaft head and the stirring shaft are on the same vertical axis.

Preferably, the shaft sleeve and the shaft head are matched with each other.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses owing to through bearing box, axle sleeve and supporting seat bolted connection, when needing the maintenance end bearing, as long as dismantle above-mentioned each parts one by one when changing the axle sleeve, just can effectual required process of completion for this end bearing all is going on in reation kettle or stirred tank outside when dismantling, installing and overhauing, and is convenient simple and direct, has saved the trouble that the people got into reation kettle or stirred tank inside and install the maintenance.

fig. 2 is an enlarged structural diagram a of the present invention.

In the figure: 1-a shaft head; 2-shaft sleeve; 3, bearing bush; 4-a support seat; 5-a vent; 6-stirring tank; 7-bearing box.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a novel end bearing, includes

agitator tank

6, 6 bottoms of agitator tank are close to axle center department fixed mounting has supporting seat 4, there is axle sleeve 2 through bolt fixed mounting in the inside axle center department of being close to of supporting seat 4, axle sleeve 2 upper end runs through supporting seat 4 and extends to agitator tank 6 inside, axle sleeve 2 is inside to be rotated and installs spindle nose 1, spindle nose 1 fixed connection is in the (mixing) shaft bottom, supporting seat 4 and axle sleeve 2 bottom extend to agitator tank 6 outside and cover and have bearing box 7, bearing box 7 bottom is close to axle center department fixed mounting has drain 5, owing to through bearing box 7, axle sleeve 2 and supporting seat 4 bolted connection, when needing maintenance end bearing, as long as pull down bearing box 7 earlier when changing axle sleeve 2, then pull down axle sleeve 2 from supporting seat 4 can, just can effectual required process of completion for this end bearing is dismantling, The installation and the maintenance are carried out outside the reaction kettle or the stirring tank, the operation is convenient and simple, and the trouble that people enter the reaction kettle or the stirring tank to carry out the installation and the maintenance is saved.

The bearing bush 3 is embedded between the shaft sleeve 2 and the supporting seat 4, so that the connection stability between the supporting seat 4 and the shaft sleeve 2 can be improved.
