Abstract

The invention discloses a bearing box, which is composed of an upper bearing cap (2), a bearing box body (4), a support (5) and a lower bearing cap (6) in order. The joint of the bearing box body (4) and a connecting shaft (1) inside are provided with an upper bearing (7), an isolating ring (8) and a lower bearing (9) from top to bottom, and the joint of the upper bearing cap (2) and the connecting shaft (1) as well as the joint of the lower bearing cap (9) and the connecting shaft (1) are both provided with a sealing ring (3). The invention has the advantages of low loss, infrequent oil leakage and stable operation.

Description

A kind of bearing housing
Technical field
The present invention relates to the machinery field, especially relate to a kind of bearing housing.
Background technique
Traditional bearing housing adopts the opposite opened structure; Be labyrinth seal between end cover and the seal ring, because sealing channel is too short in the face of lubricant oil is revealed away along the short labyrinth channel that end cover fish seal ring constitutes easily, when the stirrer high speed rotating; Lubricant oil can be splashed on the end cover inwall; Along avoiding flowing in the clearance groove of end cover fish seal ring, the minimum point from clearance groove spills again behind the aggregation, and the fluid in the bearing housing reduces gradually like this; The safe handling of direct threats equipment, and cause the waste of lubricant oil; And traditional bearing housing, because its connection set that is used for fixing is prone to wear out, wearing and tearing, and bearing housing is in the state that runs up for a long time, causes its working life not long.
Summary of the invention
The present invention is in order to solve not long problem of present bearing box oil leakage, working life; A kind of bearing housing is provided for this reason; Be arranged in order from top to down by upper ball cover 2, bearing housing 4, support 5 and lower ball cover 6 and form; Joint with joining shaft 1 in the said bearing housing 4 from top to bottom is provided with upper bearing (metal) 7, isolating ring 8 and lower bearing 9, and said upper ball cover 2 is equipped with seal ring 3 with lower ball cover 9 and joining shaft 1 joint.
Bearing housing of the present invention, said bearing housing 4 and support 5, upper ball cover 2 all is connected through bolt with bearing housing 4.
The invention has the beneficial effects as follows:
Owing between upper bearing (metal) and lower bearing, be provided with isolating ring, reduced the loss that friction causes, and all be provided with seal ring, not easy oil leakage at metal (upper lid place; And bearing housing and support, upper ball cover and bearing housing when running up, still can keep stable all through bolt, and working life is elongated.
Description of drawings
The present invention will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a bearing housing sectional view of the present invention.
Embodiment
Disclosed all characteristics in this specification, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.
Disclosed arbitrary characteristic in this specification (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
Bearing housing as shown in Figure 1; Be arranged in order from top to down by upper ball cover 2, bearing housing 4, support 5 and lower ball cover 6 and form; Joint with joining shaft 1 in the said bearing housing 4 from top to bottom is provided with upper bearing (metal) 7, isolating ring 8 and lower bearing 9, has reduced the loss that friction causes; Said upper ball cover 2 is equipped with seal ring 3, not easy oil leakage with lower ball cover 9 and joining shaft 1 joint; Said bearing housing 4 and support 5, upper ball cover 2 all is connected through bolt with bearing housing 4, when running up, still can keep stable, long service life.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.

Claims (2)
