Abstract
A low-cost eccentric bearing seat comprises an upper eccentric bearing seat, a lower eccentric bearing seat, a rotary shaft, a bearing, a shaft retaining ring and the like, wherein central lines of the bearing seats and a rotating central line of the rotary shaft have the set eccentric volume. The eccentric bearing seat is simple in manufacture process. The upper eccentric bearing seat and the lower eccentric bearing seat are formed by one-time casting through moulds, and no any precision machining is needed. In addition, the bearing seats are respectively made of zinc alloy and aluminum alloy, so that the eccentric bearing seat is light in weight, low in cost and suitable for volume production. When replaced, the bearing is convenient to dissemble and assemble, and the bearing seats are not damaged. The eccentric bearing seat is low in manufacture cost, has the same mechanical strength, service life and effect as like products, and can be widely applied to various mechanical manufacture fields.
Description
Technical field
The utility model relates to a kind of axle has eccentric core shift bearing support with bearing support, and it is cheap for manufacturing cost, can be widely used in various mechanical manufacturing field.
Background technique
Axle has eccentric core shift bearing support with bearing support, in various mechanical manufacturing field, be widely used, but because axle has off-centre with bearing support, the mechanical processing difficulty of bearing support is higher; Installation between bearing and the bearing support is higher to the required precision of Bearing Installation hole dimension; And the material of bearing support all adopts zinc alloy, Heavy Weight; Thereby this core shift bearing support manufacture cost is higher, so improve.
Summary of the invention
The purpose of the utility model is: a kind of low-cost core shift bearing support simple in structure, of high quality and at a reasonable price is provided.
The utility model is achieved in that a kind of bearing support of core shift cheaply, comprises core shift bearing support, following core shift bearing support, rotating shaft, bearing, shaft block ring and fastening screw trip bolt.Said upward core shift bearing support center line and shaft centerline have an eccentric amount e, and eccentric amount e is by distance decision between last core shift bearing support center line and the rotating shaft rotation centerline.Said Bearing Installation is in rotating shaft, by shaft block ring and shaft bearing location shoulder rigid bearing inner ring.Bearing outer ring is contained in the bearing mounting hole of core shift bearing support, and following core shift bearing support is fastened on the core shift bearing support by screw, and said core shift bearing support down is provided with bearing location shoulder, rigid bearing outer ring.
In the utility model, in the assembly of said bearing and rotating shaft, bearing can be a single bearing, also can be the combination of two bearings.
In the utility model, the said core shift bearing support of going up adopts zinc alloy and aluminum alloy material respectively with following core shift bearing support, all uses the mould one-step die casting, and the installation of bearing need not again through precision optical machinery processing owing to be provided with down core shift bearing location shoulder.The original zinc alloy that all adopts of the material of bearing support adopts zinc alloy and aluminum alloy material now respectively.
The beneficial effect of the utility model is under the prerequisite of same mechanical strength and working life and effect, because architecture advances, work simplification and material change, makes core shift bearing support manufacture cost reduce weight saving.
Description of drawings
Fig. 1: core shift bearing block structure figure cheaply.
Embodiment
Do further explain below in conjunction with 1 pair of the utility model of accompanying drawing:
A kind of bearing support of core shift cheaply comprises core shift bearing support 1, following core shift bearing support 2, rotating shaft 3, bearing 4, shaft block ring 5 and fastening screw trip bolt 6.Said upward core shift bearing support 1 center line and rotating shaft 3 center lines have an eccentric amount e, and eccentric amount e is by distance decision between last core shift bearing support 1 center line and rotating shaft 3 rotation centerlines.Said bearing 4 is installed in the rotating shaft 3; By shaft block ring 5 and shaft bearing location shoulder 31 rigid bearings 4 inner rings; Bearing 4 outer rings are contained in the bearing mounting hole 11 of core shift bearing support 1; Following core shift bearing support 2 is fastened on the core shift bearing support 1 by fastening screw trip bolt 6, and said core shift bearing support 2 down is provided with down core shift bearing location shoulder 21, rigid bearing 4 outer rings.
In the assembly of said bearing 4 and rotating shaft 3, bearing 4 can be a single bearing, also can be the combination of two bearings.
The said core shift bearing support 1 of going up adopts zinc alloy and aluminum alloy material respectively with following core shift bearing support 2, all uses the mould one-step die casting, and the installation of bearing 4 need not again through precision optical machinery processing owing to be provided with down core shift bearing location shoulder 2 l.
A kind of core shift cheaply of the utility model bearing support is not limited to above embodiment, and those skilled in the art make the change of unsubstantiality, all should fall into the protection domain of the utility model.
