Description

Bearing housing and roller vibration wheel having the same

Technical field

The present invention relates to the field of vibratory rollers, and more particularly to a bearing housing and a roller vibrating wheel having the bearing housing. Background technique

The vibratory roller is an important equipment for compacting the road surface during road construction. The vibratory roller touches the ground with the vibrating wheel, and applies a rolling pressure to the paving layer material with a linear load accompanied by high-frequency vibration, as the number of rolling increases The material is gradually compacted.

The vibrating wheel is an extremely important component for vibrating compaction. Currently, the bearings in the vibrating wheel are mounted in the housing. The working conditions of the bearings in the vibrating wheel are very harsh, especially for large-tonnage road rollers, where the bearings are rotated at high speeds under alternating load conditions of up to 400 KN. In such a working environment, the bearings usually generate a large amount of heat. If the heat cannot be dissipated in time, the bearing life will be directly reduced, which will affect the reliability of the roller.

In order to improve the working conditions of the bearing, the industry has proposed some solutions to improve the structure of the bearing housing and use cooling lubricant to dissipate heat from the bearing.

One side of the portion 12' is provided with a rib 14', a slinger 16', an oil guide 18', and an oil guiding hole 104' and a circumferential oil guiding groove 106', and the other side of the fixing portion 12' is not provided. element. Further, the tubular portion 10 is also located only on one side of the fixed portion 12, and the cylindrical portion 10 and the end portion of the fixed portion 12 are flush with the fixed portion 12'. That is, the fixing portion 12' extends radially outward from the end of the outer wall 10' of the cylindrical portion 10' and is annular.

Referring to FIG. 5, a roller vibration wheel to which the bearing housing 1 of the first embodiment of the present invention and the bearing housing 第二 of the second embodiment of the present invention are applied includes a vibration shaft 4, and bearings 2 and 2' supporting the vibration shaft 4 , the bearing housings 1 and Γ supporting the bearings 2 and 2', and the vibrating wheel body 3.

The vibrating wheel body 3 includes an outer ring 31, an inner ring 33, an outer auxiliary plate 35, and an inner auxiliary plate 37. The outer ring 31 and the inner ring 33 are hollow cylinders which are open at both ends, and the inner ring 33 has a diameter smaller than the diameter of the outer ring 31 and is coaxially disposed with the outer ring 31.

The inner auxiliary plate 37 is annular and disposed in the inner ring 33 and located in the middle of the inner ring 33.

The bearing housing 1 of the first embodiment of the present invention is fixed in the inner sub-plate 37 of the vibrating wheel body 3 by bolts (not shown), and a pair of bearings 2 are provided in the bearing housing 1. A bearing housing 第二 according to a second embodiment of the present invention is disposed in each of the two outer auxiliary plates 35 of the vibrating wheel body 3, and the bearing housing Γ is fixed to the outer auxiliary plate 35 by bolts, and has a side of the oil storage chamber 19' It is disposed toward the direction of the inner sub-board 37. A bearing 2' is placed in the bearing housing Γ. The two vibrating shafts 4 are respectively disposed between the bearing 2' in the bearing housing 上 on the outer sub-plate 35 and one bearing 2 in the bearing housing 1 in the inner sub-plate 37, and each of the vibrating shafts 4 is provided with an eccentric block 41. Thus, in the inner auxiliary plate 37 of the vibrating wheel 3, two Two independent closed spaces are formed between the bearing housings and the bearing housing 1, and a certain amount of cooling lubricating oil is previously placed in the two spaces, and the lubricating oil forms a lubricating oil zone at the bottom of the space. .

Thus, when the roller travels and the roller of the roller rotates, the vibrating wheel body 3 rotates. For example, when the clockwise rotation is performed, both the bearing housings Γ and the bearing housing 1 rotate with the vibrating wheel body 3. A plurality of oil storage chambers 19 in the clockwise direction of the bearing housing 1 sequentially enter the lubricating oil zone 39, and a certain amount of lubricating oil is carried out when the oil storage chamber 19 leaves the lubricating oil zone 39, with further rotation of the bearing housing 1 After the oil storage chamber 19 reaches a certain height (substantially to a horizontal position), the lubricating oil in the oil storage chamber 19 starts to flow into the bearing receiving chamber 103 through the oil guiding hole 104, and flows through the oil guiding groove 105 and the circumferential oil guiding groove 106 to Around the bearing 2, take away the heat of the bearing 2. Finally, the lubricating oil will flow back to the lubricating oil zone 39, and after cooling, it will be taken out by the oil storage chamber 19. Similarly, a plurality of oil reservoirs 19' in the clockwise opening toward the clockwise direction enter the lubricating oil zone 39 in sequence, and with a certain amount of lubricating oil when the oil reservoir 19' leaves the lubricating oil zone 39, when the oil reservoir 19 'After reaching a certain height (substantially to the horizontal position), the lubricating oil in the oil reservoir 19' begins to flow into the bearing accommodating chamber 103' through the oil guiding hole 104', and flows through the oil guiding groove 105' and the circumferential oil guiding groove 106'. To the bearing 2' around. Thus, as the vibrating wheel 3 rotates, a large amount of lubricating oil is continuously brought to the bearings 2 and 2', and then flows along the oil guiding hole 104', the oil guiding groove 105' and the circumferential oil guiding groove 106', to the bearing 2 and 2' around, the effect of lubricating bearings 2 and 2' is achieved, the temperature of bearings 2 and 2' is lowered, and the service life of bearings 2 and 2' is extended.

The same is true when the roller is retracting. When the roller of the roller rotates, the vibrating wheel body 3 rotates. At this time, it rotates counterclockwise, and both the bearing housing Γ and the bearing housing 1 rotate with the vibrating wheel body 3. Housings Γ and housings 1 The oil reservoirs 19' and 19 with the opening facing counterclockwise are sequentially entered into the lubricating oil zone 39 to extract the lubricating oil. The subsequent process is as described above and will not be described here.

It can be understood that in other embodiments of the bearing housing of the present invention, each pair of oil guiding holes 104 may not communicate with each oil guiding groove 105 and each circumferential oil guiding groove 106, but each pair of oil guiding holes 104 is in communication with each of the oil guiding grooves 105, but is not in communication with the circumferential oil guiding groove 106, and each oil guiding groove 105 is in communication with the circumferential oil guiding groove 106; or each pair of oil guiding holes 104 is in communication with the circumferential oil guiding groove 106, but is not in communication with the oil guiding groove 105.

The lower ends of the respective oil guiding holes 104 may not be in contact with each other, but communicate with the respective oil guiding grooves 105, and the axes of the respective oil guiding holes 104 may not be on the same plane, but may be staggered.

It will also be appreciated that in other embodiments of the bearing housing of the present invention, the plurality of oil guiding grooves 105 may extend non-axially on the inner wall 102 of the tubular portion 10, but may extend obliquely, for example, in a spiral shape. The circumferential oil guiding groove 106 may not be located on a plane perpendicular to the axis of the inner wall 102 of the cylindrical portion 10, but may be inclined.

It can be understood that the bearing housing of the preferred embodiment of the present invention can be applied not only to the vibrating wheel of the vibratory roller, but also to other machines that need to dissipate heat for the bearings in the bearing housing, such as a high temperature pump.
