AI Technical Summary
Due to the inconsistent taper of the shaft wall and the shaft hole in the traditional positive pressure wheel installation structure, the surface contact becomes linear contact, resulting in large wear, severe shaking, high frequency of wheel shaft replacement, and poor overall effect.
An annular groove is opened in the shaft hole to form an annular protrusion, reducing the contact part with the shaft, so that there is a certain machining error between the annular protrusion and the shaft wall, ensuring that there are contact parts in the front and rear, and ensuring stable transmission and small shaking.
By reducing the contact part with the shaft, the transmission is ensured to be stable, shaking is small, wear speed is slow, maintenance frequency is low, the overall function is perfect, and practical.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical equipment, and more specifically, to a positive pressure wheel installation structure for stainless steel hose production. Background Art
[0002] The production equipment of metal hoses with double buckle or single buckle structures are equipped with a positive pressure wheel that plays a flanging role. The positive pressure wheel is usually rotatably connected to the mounting seat through a shaft. The hole on the traditional mounting seat that adapts to the shaft has a certain taper, and the taper matches the shaft wall so that the two can fit tightly together. Due to the existence of processing errors, it is difficult to ensure that the taper of the shaft wall is consistent with the taper of the shaft hole, causing the original surface contact to become line contact. Long-term use will cause great wear and tear, and it is easy to shake. The frequency of wheel and shaft replacement increases, and the overall effect is not good. Based on this, the utility model proposes a positive pressure wheel installation structure for stainless steel hose production. Summary of the invention
[0003] The utility model aims to overcome the deficiencies in the prior art and to provide a positive pressure wheel installation structure for stainless steel hose production, which has the characteristics of smooth transmission and no jitter.
[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows: the utility model involves a positive pressure wheel installation structure for stainless steel hose production, including a pressure wheel installation seat, an axial hole is opened on the pressure wheel installation seat, a pressure wheel shaft is rotatably connected in the axial hole, a positive pressure wheel is arranged on the pressure wheel shaft, the axial hole is a tapered hole, the outer wall surface of the pressure wheel shaft matches the inner wall surface of the axial hole, an annular groove is opened on the hole wall of the axial hole, and the front and rear sides of the annular groove respectively form annular protrusions arranged on the hole wall of the axial hole, and the annular protrusions are tightly attached to the pressure wheel shaft.
[0005] To sum up, the utility model has the following beneficial effects: the positive pressure wheel installation structure for the production of stainless steel hoses involved in the utility model reduces the contact part with the shaft by grooving in the tapered shaft hole, resulting in a certain processing error between the annular protrusion formed before and after the annular groove and the shaft wall. Because there are contact parts at the front and back, the transmission is smooth, the jitter is small, the wear speed is slow, the maintenance frequency is low, the overall function is perfect, and the practicality is strong. BRIEF DESCRIPTION OF THE DRAWINGS
[0006] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION
[0007] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.
[0008] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments. Example
[0009] See also Figure 1 As shown, the present embodiment involves a positive pressure wheel installation structure for stainless steel hose production, comprising a pressure wheel installation seat 1, an axial hole 2 is opened on the pressure wheel installation seat 1, a pressure wheel shaft 3 is rotatably connected in the axial hole 2, a positive pressure wheel (not shown) is arranged on the pressure wheel shaft 3, the axial hole 2 is a tapered hole, the outer wall surface of the pressure wheel shaft 3 matches the inner wall surface of the axial hole 2, an annular groove 4 is opened on the hole wall of the axial hole 2, and annular protrusions 5 arranged on the hole wall of the axial hole 2 are respectively formed on the front and rear sides of the annular groove 4, and the annular protrusions 5 are tightly attached to the pressure wheel shaft 3.
[0010] In this embodiment, if the machining accuracy can be guaranteed, the annular protrusion 5 and the pressure roller shaft 3 are in surface contact, which is an ideal state with a large contact area and small wear. However, in reality, the annular protrusion 5 on the front side of the annular groove 4 forms a closed ring line contact with the pressure roller shaft 3, and the annular protrusion 5 on the rear side forms a closed ring line contact with the pressure roller shaft 3. Because there is contact between the front and rear, the shaft can be kept relatively stable during rotation with small jitter.
[0011] The positive pressure wheel installation structure for the production of stainless steel hoses involved in the utility model reduces the contact portion with the shaft by slotting in a tapered shaft hole, resulting in a certain processing error between the annular protrusions formed before and after the annular groove and the shaft wall. Since there are contact portions at the front and back, smooth transmission, small jitter, slow wear, low maintenance frequency, complete overall functions and strong practicality are guaranteed.
