Description
Technical Field
The utility model relates to a concatenation formula axle sleeve.
Background
The shaft sleeve is a component which is sleeved outside the shaft and protects the shaft. When the shaft rotates or moves linearly, the shaft sleeve wrapped outside the shaft instead of the shaft rubs against the housing or other parts.
Current axle sleeve is mostly the fixed structure of integrated into one piece and size, and to the axle of different length, the unable adjustment that realizes of length of axle sleeve.
In addition, most of the existing shaft sleeves are sleeved outside the shaft and only have the function of protecting the shaft. And to some special cases, need fix axle middle part on fixed subassembly such as support, perhaps need establish the bearing at axle middle part cover, because the axle sleeve cladding is outside the axle, support or bearing can only be installed on the axle sleeve, and current axle sleeve needs linking bridge or cover to establish the bearing and must be at axle sleeve surface milling hole, adopts threaded connection, perhaps adds spacing subassembly and carries on spacingly, has increased the cost of customization axle sleeve.

In order to achieve the purpose, the technical scheme of the utility model is to design a splicing type shaft sleeve, which comprises a shaft sleeve upper end component, a gasket and a shaft sleeve lower end component;
the upper part of the shaft sleeve upper end component is of a cylindrical sleeve structure, the lower part of the shaft sleeve upper end component is provided with two axisymmetric arc-shaped inserting pieces, and the arc-shaped inserting pieces are provided with a plurality of transverse grooves;
the lower end assembly of the shaft sleeve is of a cylindrical sleeve structure, an annular groove is formed in the middle of the side wall of the lower end assembly of the shaft sleeve, a plurality of cross rods are arranged in the left end and the right end of the annular groove from top to bottom, and two ends of each cross rod are respectively connected with the side walls on two sides of the annular groove;
the gasket is sleeved on the arc-shaped inserting piece of the upper end assembly of the shaft sleeve;
the arc inserted sheet of axle sleeve upper end subassembly can insert the annular of axle sleeve lower extreme subassembly, and the horizontal pole card of axle sleeve lower extreme subassembly is gone into in the transverse groove of the arc inserted sheet of axle sleeve upper end subassembly in the rotation axis sleeve upper end subassembly.
Preferably, the arc-shaped inserting sheet is provided with two transverse grooves; two cross rods are arranged at the left end and the right end of the annular groove from top to bottom.
The utility model has the advantages and the beneficial effects that: the utility model relates to a concatenation formula axle sleeve, this axle sleeve make up through the concatenation of axle sleeve upper end subassembly and axle sleeve lower extreme subassembly, and axle sleeve length can be adjusted, and the axle sleeve middle part can directly set up bearing or support.
