Abstract
The utility model discloses a stepped shaft assembly, which comprises a stepped shaft and a stepped assembly sleeve. The middle section of the stepped shaft is of the same diameter, and is provided with tow positioning grooves, which are matched with a clamp hoop; the clamp hoop is arranged on one side of the stepped assembly sleeve; a matching hole of the clamp hoop and the stepped shaft is a stepped hole. The utility model is applied in an escalator, and as the utility model adopts a structure of the same diameter, the structure is simpler, thereby simplifying the processing technology, reducing processing steps, shortening processing time, facilitating assembly and cutting off producing cost.
Description
Technical field
The utility model relates to a kind of step axle assembly, is specifically related to a kind of escalator step axle assembly.
Background technique
Present employed escalator step axle, step is installed on the intermediate portion of step axle.In order to match with step, the intermediate section of dress step is generally the labyrinth of many step types on the step axle, as shown in Figure 1.During use, the intermediate section that is installed in step axle is overlapped in the step assembling, again step and step assembling cover are matched, can finish the installation of step, as shown in Figure 2.The step axle of the labyrinth of this many step types, not only complex structure, and processing technology is loaded down with trivial details, and manufacturing procedure is many, and is not only time-consuming but also take material, more improved cost of production.
The model utility content
The technical problems to be solved in the utility model provides a kind of step axle assembly, and this step axle modular construction is simple, processes easy.
For solving the problems of the technologies described above, the technical solution of the utility model step axle assembly is:
The step assembling that comprises step axle and be assemblied on the step axle is overlapped, and wherein, described step axle intermediate section is same diameter, and intermediate section is provided with two positioning grooves, and positioning groove matches with clamp.
Further, described clamp is arranged at a side of step assembling cover.
Further, the matching hole of described clamp and step axle is a step hole.
The utility model step axle assembly, owing to adopt the step axle of single diameter structure, structure is simpler, thereby has simplified processing technology, has reduced process step, has shortened machining period, assembles also conveniently, has reduced cost of production.
Adopt the utility model, the step axle diameter is littler than step axle diameter of the prior art, thereby weight is also just lighter, and the power of motor that is complementary with escalator also reduces thereupon, thereby has saved the operating cost of escalator for applying unit.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the schematic representation of step axle in the prior art;
Fig. 2 is the erection drawing of prior art step axle assembly;

Fig. 6 is the sectional view of Fig. 5 along A-A;
Fig. 7 is one of erection drawing of the utility model step axle assembly;
Fig. 8 be the utility model step axle assembly erection drawing two.
Among the figure, 1 step axle, 2 steps assembling cover, 3 clamps, 4 bolts, 5 nuts.
Embodiment
As shown in Figure 3, step axle 1 intermediate section is same diameter, and intermediate section is provided with two positioning grooves.Positioning groove is used for the location of step axle.
As shown in Figure 7, during use, step assembling cover 2 is assemblied on the step axle 1, again clamp 3 is locked in the positioning groove on the step axle 1 by bolt 4 and nut 5, make step assembling cover 2 location.Step is installed on the step assembling cover 2, and step just can not left and right sides play.
The structure of clamp 3 such as Fig. 4, Fig. 5, shown in Figure 6 during use, are assemblied in clamp 3 in the positioning groove of step axle 1 by bolt 4 and nut 5.In the present embodiment, for ease of installing, hexagonal cylinder head bolt and square nut in adopting for fixing clamp 3 better, are provided with compression spring and flat gasket between bolt 4 and clamp 3.
In order to match with step axle 1 better, clamp 3 is a step hole with the matching hole of step axle 1.In the present embodiment, the endoporus B of the matching hole of clamp 3 and step axle 1 is greater than hole A.
As Fig. 7, shown in Figure 8,, clamp 3 can be installed on any side of step assembling cover 2 according to different needs.
Claims (4)
1. a step axle assembly comprises step axle and the step assembling cover that is assemblied on the step axle, it is characterized in that described step axle intermediate section is same diameter, and intermediate section is provided with two positioning grooves, and positioning groove matches with clamp.
