Abstract
The invention discloses a cantilever type riding wheel shaft. The cantilever type riding wheel shaft comprises a shaft body. The shaft body comprises an installation segment and a fixed segment, wherein the installation segment and the fixed segment are of an integrated structure. The installation segment is used for installing a riding wheel. The fixed segment is used for realizing supporting. The installation segment is provided with a conical peripheral surface. The fixed segment is provided with a cylindrical peripheral surface. A shaft shoulder is arranged between the installation segment and the fixed segment. Two supporting bearings are arranged on the fixed segment in a spaced mode. A spacer bush is arranged between the two supporting bearings. According to the cantilever type riding wheel shaft, the conical installation segment of the shaft body is used for installing the riding wheel and well matched with the riding wheel, the riding wheel can be directly arranged on the installation segment of the shaft body in a sleeved mode, and therefore installation is convenient; the two supporting bearings are used for realizing supporting, so that stability in the transmission process is guaranteed, and transmission accuracy is improved.
Description
Technical field
The present invention relates to a kind of cantilever type supporting-roller shaft.
Background technique
Chain transmission, with transmission, it is the kind of drive conventional in mechanical transmission, needs due to technological requirement, some occasion underdrive route is longer, for keeping stable drive, several support rollers are often set in the middle of transmission system, be used for supporting Transmitted chains or driving belt, and the supporting-roller shaft of support roller station, owing to being only supplemental support effect, general accuracy of manufacturing is often lower, and install comparatively loaded down with trivial details, support roller relies on key to be connected with supporting-roller shaft, in support roller and supporting-roller shaft, need to process keyway, if support roller is enclosed within supporting-roller shaft, axially with pressing plate, compress, easily produce that to coordinate tension to affect transmission smooth and easy or coordinated pine not have due supporting effect.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency of prior art, provide a kind of and can realize the cantilever type supporting-roller shaft that support roller is easy for installation, quality of fit is better, support effect is desirable.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cantilever type supporting-roller shaft, comprise axis body, described axis body has integrative-structure for construction section and the holding part for supporting of support roller are installed, described construction section has taper outer circumferential face, described holding part has cylindricality outer circumferential face, between construction section and holding part, have the shaft shoulder, on holding part, spaced apart is provided with two spring bearings, between two spring bearings, is provided with spacer.
Further, sympodium shoulder side is close in the spring bearing side of paraxial shoulder.
Described holding part tail end is provided with gland, and gland is pressed on end face outside the spring bearing of the shaft shoulder far away, and holding part tail end center offers tapped hole, is equipped with the housing screw being connected with tapped hole by gland center.
The invention has the beneficial effects as follows: in the present invention, the axis body construction section that support roller is installed is taper, works good with support roller, support roller is directly enclosed within on axis body construction section, easy for installation, and two spring bearings support, guarantee the stability in transmission process, be conducive to improve transmission accuracy.

Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
A kind of cantilever type supporting-roller shaft as shown in Figure 1 and Figure 2, comprise axis body 1, described axis body 1 has integrative-structure for construction section 11 and the holding part 12 for supporting of support roller are installed, described construction section 11 has taper outer circumferential face, described holding part 12 has cylindricality outer circumferential face, between construction section 11 and holding part 12, have the shaft shoulder 13, on holding part 12, spaced apart is provided with between 2, two spring bearings 2 of two spring bearings and is provided with spacer 3.
Spring bearing 2 sides of paraxial shoulder 13 are close to sympodium and are takeed on 13 sides.
Described holding part 12 tail ends are provided with gland 4, and gland 4 is pressed on the spring bearing 2 outside end faces of the shaft shoulder 13 far away, and holding part 12 tail end centers offer tapped hole 14, are equipped with the housing screw 5 being connected with tapped hole 14 by gland 4 centers.
Axis body 1 construction section 11 that support roller is installed in invention is taper, works good with support roller, and support roller is directly enclosed within on axis body 1 construction section 11, easy for installation, and two spring bearings 2 support, and have guaranteed the stability in transmission process, are conducive to improve transmission accuracy.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
