Abstract
The utility model discloses a reliable gapless connection device for a shaft. The reliable gapless connection device for the shaft comprises an inner ring, an outer ring, an inner cone, an outer cone and bolts, wherein the inner ring is matched with the outer surface of the shaft, the outer ring is matched with the inner surface of a connected part, the inner cone and the outer cone are arranged in a gap between the inner ring and the outer ring, external threads of the bolts are matched with internal threads of the inner cone and internal threads of the outer cone, and a gap exists between the inner cone and the outer cone before the bolts are screwed into the reliable gapless connection device. The reliable gapless connection device for the shaft is simple in structure, it is ensured that the shaft and the part can be connected in a gapless mode, disassembly and assembly are convenient, the structural form of the shaft is unchanged, and influence is not caused to the strength and deformation of the shaft.
Description
Technical field
The utility model belongs to mechanical transmissioning technology field, particularly the reliable connection set of a kind of axle gapless.
Background technique
The Placement of part and axle, different with the effect of part.Generally, in order to guarantee that part has definite working position on axle, need be fixed from axial and circumferential.
The axial restraint of existing parts on shaft and circular fixation mode are connected, sell fixing and three kinds of modes of cooperation really up to the mark as main take key.Wherein the manufacture of key Placement is simple, mounting or dismounting are convenient, can transmit compared with high pulling torque, but on axle, keyway has weakened to a certain extent the intensity of axle and coordinated accurate not.Pin fixed form has requirement to the difference of hardness of axle and union piece, and dismounting is also inconvenient.These two kinds are connected and fixed mode meeting generation gap in the long-term process using, and affect the transmission capacity of axle.
Cooperating structure really up to the mark is simple, and centering is good, and bearing capacity is high, can play circumferential and circumferential fixation simultaneously, but is not suitable for the occasion for normal dismounting.
Model utility content
It is a kind of simple in structure that the purpose of this utility model is to provide, and can not only guarantee to be connected gapless between axle and part, and easy accessibility, do not change the self structure form of axle, on the strength and deformation of axle all without the reliable connection set of axle gapless affecting.
The technical solution that realizes the utility model object is:
The reliable connection set of a kind of axle gapless, comprises inner ring, outer ring, inner cone body, outer cone body, bolt; Wherein, inner ring matches with the outer surface of axle, match with the internal surface of union piece in outer ring, inner cone body and outer cone body are arranged in the gap between inner ring and outer ring, the outside thread of bolt matches with the internal thread of inner cone body and outer cone body, and inner cone body and outer cone body are gapped before bolt screws in.
The utility model compared with prior art, its remarkable advantage:
The utility model is simple in structure, can not only guarantee to be connected gapless between axle and part, and easy accessibility, does not change the self structure form of axle, on the strength and deformation of axle all without impact.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the reliable connection set of the utility model axle gapless.
Fig. 2 is the use schematic diagram of the reliable connection set of the utility model axle gapless.
Embodiment
Shown in Fig. 1 and Fig. 2:
