Description

A kind of taper roll bearing spacer ring

Technical field

This utility model is related to technical field of bearings and in particular to a kind of taper roll bearing spacer ring.

Background technology

The outer ring of double-row conical bearing or inner ring are an entirety, and two inner rings or outer ring small end face are close, middle It is provided with spacer ring, clearance is that the thickness by spacer ring to adjust.Existing spacer ring, is with circular ring type structure it is difficult to meet existing The demand of various structures bearing.Particularly, when annulus end face band is raised, the operative end surface of spacer ring annulus cannot be in surface grinding machine Upper mill processing, needs the method processing by wire cutting or milling.Wire cutting fast wire winding roughness and the width variation amount of end face All it is unable to reach requirement, slow wire feeding roughness can reach requirement, the width variation amount of end face still slightly deviation, and efficiency is low, Costly, milling method precision relatively low it is impossible to reach the required precision of operative end surface.

Utility model content

The purpose of this utility model is to provide a kind of taper roll bearing spacer ring.

The technical scheme that this utility model is adopted is：A kind of taper roll bearing spacer ring, including cirque structure Spacer ring body, the center of spacer ring body is provided with the central through hole of its upper and lower end face of insertion, also includes four contiguous blocks, each contiguous block Center be equipped with screwed hole, the edge of spacer ring body is provided with two threaded mounting holes, threaded mounting hole insertion spacer ring body Upper and lower end face, two-by-two contiguous block be separately fixed at the upper and lower side of spacer ring body after screw passes through screwed hole and threaded mounting hole On face, wherein, the upper and lower end face of each contiguous block is plane, and the inner and outer circumferential surfaces of each contiguous block are all in the edge shape with spacer ring body The consistent cambered surface of shape.

Wherein, two described threaded mounting holes are located at the same diameter of spacer ring body radially.

In this utility model, the screwed hole at two of which contiguous block center is screw-threaded counterbore, so that the upper surface of screw is not surpassed Cross the upper surface with contiguous block, wherein, the lower surface flush of the lower surface of screw and contiguous block.

Further, the upper surface of screw is less than the upper surface 0.5～1mm of contiguous block.

In this utility model, the internal diameter of contiguous block is identical with the internal diameter of spacer ring body, the external diameter of contiguous block and spacer ring body External diameter identical.

Because using technical scheme as above, this utility model has following superiority：This utility model adopts will Contiguous block is detachably connected with spacer ring, in use, can be by the operative end surface completion of processing of spacer ring body on surface grinding machine Afterwards, then by contiguous block link up with spacer ring, so that spacer ring precision is significantly improved, solve taper roll bearing and use Spacer ring precision is unable to reach a difficult problem for drawing requirement, improves bearing accuracy and service life, is particularly suited for mass production.

Specific embodiment

With reference to specific embodiment, the utility model is described in further detail, so that those skilled in the art can be more Good understanding this utility model simultaneously can be practiced, but illustrated embodiment is not as to restriction of the present utility model.

A kind of taper roll bearing spacer ring, as depicted in figs. 1 and 2, including the spacer ring body 1 of cirque structure, spacer ring The center of body 1 is provided with the central through hole 2 of its upper and lower end face of insertion, also includes four contiguous blocks 3, and the center of each contiguous block 3 is equal Be provided with screwed hole 4, the edge of spacer ring body 1 is provided with two threaded mounting holes 5, threaded mounting hole 5 insertion spacer ring body 1 upper and lower End face, two threaded mounting holes 5 are located at the same diameter of spacer ring body 1 radially.

In the prior art, the inwall of bearing inner race is additionally provided with two along its axially arranged locking groove, two locking grooves Positioned at bearing inner race same radially, the width ratio locking groove of contiguous block 3 upright projection on spacer ring body 1 is in spacer ring body Little 1～the 2mm of width of upper upright projection.

Wherein, contiguous block 3 is passed through by screw 6 and is separately fixed at spacer ring body after screwed hole 4 and threaded mounting hole 5 two-by-two On 1 upper and lower end face, wherein, the upper and lower end face of each contiguous block 3 is plane 30, the inner and outer circumferential surfaces of each contiguous block 3 all in every Enclose the consistent cambered surface 31 of the edge shape of body 1, the internal diameter of contiguous block 3 is identical with the internal diameter of spacer ring body 1, outside contiguous block 3 Footpath is identical with the external diameter of spacer ring body 1；As shown in figure 1, the screwed hole at two of which contiguous block 3 center is screw-threaded counterbore, make spiral shell The upper surface of nail 6 is less than the upper surface with contiguous block 3, wherein, the lower surface flush of the lower surface of screw 6 and contiguous block 3, The upper surface of screw 6 is less than the upper surface 0.5～1mm of contiguous block 3.

The spacer ring with contiguous block of this utility model taper roll bearing, after fractionation, spacer ring body 1 just can be general Surface grinding machine on mill process its operative end surface 4 so that the precision of the operative end surface of spacer ring body 1 reaches drawing requirement, then, Spacer ring body 1 is linked into an integrated entity by screw 6 with contiguous block 3.Spacer ring body 1 is divided into by this utility model with contiguous block 3 Split type structure, convenient disassembly, low machining expense；Work efficiency is high, and stock utilization is high, can greatly improve spacer ring essence Degree, thus improve precision and the service life of bearing, is more suitable for producing in batches.
