The utility model is characterized in that thrust bearings are respectively arranged between the same set of inner and outer supporting sleeves with variable cross sections to form a thrust bearing set which is arranged in the supporting sleeve barrel; the thrust bearings are composed of bearing straining rings, bearing loose rings, rollers and cage sets; the outer supporting sleeves with variable profiles are cooperated with the bearing loose rings and the supporting sleeve barrel; the inner supporting sleeves with variable profiles are cooperated with the bearing loose rings and the shaft; the front part of the thrust bearing set is provided with the radial bearing support; both of the cross sections of the inner supporting sleeves and the outer supporting sleeves are variable cross sections; the inner supporting sleeves are arranged on a central shaft, and the section dimensions of the inner supporting sleeves is increased gradually from bottom to top; the outer supporting sleeves are arranged in the bore of the supporting sleeve barrel, and the section dimensions of the outer supporting sleeves decrease gradually from bottom to top. The utility model has the advantages that the space structure of the bearing assembly is compact, the number of the parts is less, the load distribution is uniform, and the bearing capacity for axial loads is great.
Description
The utility model relates to the thrust bearing assembly that thrust load (hereinafter to be referred as axial force) rotating shaft is born in a kind of supporting, especially relates to a kind of variable cross section thrust bearing assembly that is applicable to twin-screw and multiple-rotor supporting.
Because its axis of multiple-rotor that bears axial force is generally and be arranged in parallel, and mutual spacing is less, therefore,, can not or be difficult to employing and have enough bearing capacitys and larger-size single thrust-bearing of the supporting of this class because of the rotating shaft that is subjected to the bulk restriction.So a lot of similar supportings at present are the thrust bearings that adopt a plurality of thrust-bearings to be composed in series.The key issue that this class supporting structure need solve is: how to guarantee the axial force uniformity that each bearing bears, this just requires passing shaft harmonious to the axial deformation of all parts of power, require each part that high geometric accuracy is arranged, axial dimension precision particularly, routine U. S. Patent (No. 3652140) are exactly to adopt the method for many pads compensation.This method is had relatively high expectations to part processing, and manufacturability is poor, and is uneconomical again.Another way is exactly domestic patent (8820481.4), adopt " screw with screw thread between mandrel and each internal support sleeve, and relative fixed, between each bearing loose ring end face and outer supporting sleeve seat ring face the dish spring is housed." but this class formation each section accuracy of screw machining of mandrel part is had relatively high expectations, and require threaded internal support block set end face very vertical with flank of thread.Therefore, its processing is difficulty, and assembling and setting is not too convenient.
The purpose of this utility model is, overcomes the shortcoming of above-mentioned prior art, and a kind of variable cross section thrust bearing assembly of new structure rotating shaft axially mounting assembly is provided, and makes that it has that bearing capacity is strong, compact structure, is easy to process and the effect of assembling and setting.
The purpose of this utility model is realized by following technological scheme.A kind of variable cross section thrust bearing assembly of supporting shaft, comprise protecgulum, fastening piece, radial bearing supporting, axle and bearing sleeve, it is characterized in that: each thrust-bearing places respectively between the inside and outside supporting sleeve of same group of variable cross section, constitute thrust bearings, and be assembled in the bearing sleeve, thrust-bearing is made up of bearing collar, bearing loose ring and roller and retainer group.
The purpose of this utility model also can further be realized by following technical measures.The outer supporting sleeve of described variable cross section and bearing loose ring match with the bearing sleeve endoporus, and the internal support sleeve of variable cross section and bearing collar match with axle, and the thrust bearings front end is provided with the radial bearing supporting.The cross section of described internal support sleeve and outer supporting sleeve is variable cross section, and internal support sleeve is installed on the central shaft, and sectional dimension increases gradually from bottom to top; Outer supporting sleeve is installed in the endoporus of bearing sleeve, and sectional dimension reduces gradually from bottom to top.That the supporting of described radial bearing can be adopted is single-row, the radial bearings of biserial or three row.Described radial bearing is roller bearing, needle bearing or hollow cylindrical roller bearing.
The utility model compared with prior art has tangible advantage and good effect.By above technological scheme as can be known, the utility model is by bearing pack that adopts the parts peculiar composition and the sectional dimension that changes internal support sleeve and outer supporting sleeve, make its compatibility of deformation unanimity when bearing axial force, and the load that each group rolling element is born is identical, can guarantee that each bearing has identical working life in the thrust bearing assembly.
In sum, the utility model is owing to adopted parts peculiar, the thrust-bearing that it is different from the employing standard adds the thrust bearings of other Component again, and has overcome its shortcoming effectively, thereby axial and radial dimension compactness, number of parts is few, make machining accuracy be easy to guarantee that load distribution is more even, assembling and setting is easy, and have the bigger ability of bearing thrust load, thereby be suitable for practicality more.
Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Fig. 1 is a structure cross-sectional schematic of the present utility model.
The utility model, comprise protecgulum ［ 1 ］, fastening screw trip bolt ［ 2 ］, radial bearing supporting ［ 3 ］, bearing sleeve ［ 4 ］, axle ［ 9 ］ and spacer ［ 12 ］, outer supporting sleeve of variable cross section ［ 6 ］ and bearing loose ring ［ 5 ］ cooperate with bearing sleeve ［ 4 ］ endoporus, internal support sleeve of variable cross section ［ 8 ］ and bearing collar ［ 7 ］ match with axle ［ 9 ］, the thrust bearings front end is provided with radial bearing supporting ［ 3 ］, be installed in jointly in bearing sleeve ［ 4 ］ endoporus, bearing sleeve ［ 4 ］ two ends are provided with protecgulum ［ 1 ］ and bonnet ［ 11 ］, in the present embodiment, should be made as one with bearing sleeve ［ 4 ］ by ［ 6 ］ bonnet ［ 11 ］.Thrust-bearing is made up of bearing collar ［ 7 ］, bearing loose ring ［ 5 ］ and roller and retainer group ［ 10 ］, wherein, internal support sleeve ［ 8 ］ is variable cross section with the cross section of outer supporting sleeve ［ 6 ］, most internal support sleeves ［ 8 ］ is installed on the axle ［ 9 ］, and its sectional dimension increases gradually from bottom to top; Outer supporting sleeve ［ 6 ］ is installed in the endoporus of bearing sleeve ［ 4 ］, and its sectional dimension reduces gradually from bottom to top.That radial bearing supporting ［ 3 ］ can be adopted is single-row, roller bearing, needle bearing or the hollow cylindrical roller bearings of biserial or three row.When the utility model is installed, be respectively charged in the bearing sleeve ［ 4 ］ by the order that bearing loose ring ［ 5 ］, outer supporting sleeve ［ 6 ］, internal support sleeve ［ 8 ］ are installed earlier in regular turn, installing roller and retainer group ［ 10 ］ between bearing loose ring ［ 5 ］ and bearing collar ［ 7 ］, after having adorned required thrust bearings number, reinstall spacer ［ 12 ］ and the axle ［ 9 ］ of radial bearing supporting ［ 3 ］ is housed, at last protecgulum ［ 1 ］ is fixed on the bearing sleeve ［ 4 ］ with screw ［ 2 ］, promptly is combined into the utility model.
