Description

Technical Field

[0001] This utility model relates to the field of spiral driven shaft technology, specifically to a horizontal spiral driven shaft. Background Technology

[0002] Due to their unique material conveying capabilities, screw shafts are widely used in many technical fields. However, the manufacturing of screw shafts has always been a very challenging technical problem. The commonly used process is to cut a steel plate into a notched ring, then process the ring into a helical blade by stretching or rolling, and then weld it to a central shaft to form a screw shaft. Finally, the concentricity of the helical blades is ensured by using a lathe or other means.

[0003] In the specification of a spiral shaft and its manufacturing method (CN105752621A after publication), it is mentioned that "the spiral blades are formed by a number of shaft stacks that are staggered and layered in a feather-like manner around the periphery of the central shaft. Further, the outer surface of the central shaft is provided with one or more keyways along the extension direction of the central shaft for fitting the shaft stacks; the shaft stacks include a bushing and spokes; the bushing has a central hole, and the central hole is provided with a positioning protrusion that matches the keyway for fitting onto the corresponding keyway of the central shaft; the spokes of the shaft stacks are arranged in staggered layers starting from the first one, and as the shaft stacks are stacked, the shaft stacks are arranged in a feather-like manner, thereby forming spiral blades around the periphery of the central shaft." However, the spiral shaft in the prior art cannot satisfy both the installation of the driven sprocket and the connection of the cantilever spiral, and is not convenient, flexible and practical. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, a horizontal helical driven shaft is provided to solve the problem that the existing helical shaft cannot satisfy both the installation of the driven sprocket and the connection of the cantilever helix, and is not convenient, flexible and practical.

[0005] To achieve the above objectives, a horizontal helical driven shaft is provided, comprising a bearing housing, a driven shaft, and a driven sprocket. A third flange is fitted onto the rear part of the bearing housing, and a driven sprocket is fitted onto the middle part of the bearing housing. The driven shaft is fitted onto the front part of the bearing housing. The centers of the bearing housing, the driven shaft, the third flange, and the driven sprocket are all located on the same axis. An end plate is mounted on the center of one side of the bearing housing, and two sets of bolts are installed between the end plate and the bearing housing.

[0006] Furthermore, a VD-shaped rubber seal is provided on the left side of the driven shaft, and a VD-shaped rubber seal is provided between the driven shaft and the first flange, and the driven shaft is a rotatable structure.

[0007] Furthermore, a common flat key is provided between the middle part of the bearing housing and the upper part of the inner sidewall of the driven sprocket, and a groove is provided in the middle of the outer ring surface of the driven sprocket.

[0008] Furthermore, a second flange is provided at the rear of the bearing housing, and an end plate is provided on the left side of the second flange. Spring washers and flat washers are fitted on the bolts installed between the end plate and the bearing housing.

[0009] Furthermore, a spacer is provided on the left side of the driven sprocket, and the spacer is fitted onto the bearing housing.

[0010] Furthermore, a third flange is provided on the right side of the second flange, and a fourth flange is provided on the right side of the third flange, with the third flange located on the left side of the spacer.

[0011] Furthermore, a lip seal is installed on the right side of the second flange, and a retaining ring for the bore is provided on the right side of the lip seal, and an SKF bearing is provided on the right side of the retaining ring for the bore.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses 1crSKF bearing material, which not only meets the requirements of the food industry, but also meets the strength and wear problems in the transmission process; it is made by welding, which greatly shortens the processing time and reduces the processing cost while ensuring sufficient strength, thereby saving costs.

[0014] 2. This utility model uses a cantilevered spiral, so the driven shaft can satisfy both the installation of the driven sprocket and the connection with the cantilevered spiral.

[0015] 3. The right end of the shaft in this utility model is a flange structure, which connects to the longer spiral in the middle, thus becoming a "connecting bridge" between the spirals on the left and right sides and the main drive, making it more convenient and practical.
