Abstract
The utility model relates to a grooved pulley, which mainly relates to a novel steel plate-type grooved pulley which is used to transmit dynamic through rotation on a portable machine The utility model mainly comprises a concave groove, a central shaft sleeve flange plate, a central shaft sleeve, a bearing, a rivet, a groove-shaped reinforced rib and a central shaft sleeve fixed plate, the inner side of the concave groove is provided with the groove-shaped reinforced rib and is integrally connected with the inner wall of the concave groove through a projecting welding technique, the center of the central shaft sleeve is provided with a bearing, one end of the central shaft sleeve is provided with the central shaft sleeve flange plate, and the central shaft sleeve flange plate is integrated with the central shaft sleeve fixed plate on the lateral face of the concave groove through the rivet, thereby constituting a novel steel plate-type grooved pulley which solves the problems that the sole weight of the traditional casting grooved pulley is big and balancing degree is bad. The grooved pulley has the advantages of simple production technique, light weight, excellent balance degree, long life span and low cost.
Description
Technical field
The utility model relates to a kind of sheave, mainly refers to a kind of new steel plate formula sheave of light mechanically usefulness.
Background technique
At present, fast development along with mechanization, light small-sized machine is more and more come into the field, life brings great convenience to Human's production, yet, on these light gadgets owing to mostly using castiron sheave, make that the own wt of the gadget that these are light is higher, and because the degree of balance of cast iron sheave is poor, vibration and shake degree are big when making the work of light small-sized machine, the wayward tilth of operator, and also cast iron manufacturing sheave needs founding technology, the time-consuming cost height of taking a lot of work easily breaks.
The model utility content
The purpose of this utility model provides a kind of new steel plate formula sheave, is keeping under the function that former cast iron sheave has, make sheave weight saving, the degree of balance is good, cost is low, manufacturing process is simple, the life-span is long.
For achieving the above object, a kind of new steel plate formula sheave of the present utility model is by race, the central axle sleeve flange plate, central axle sleeve, bearing, rivet, the grooved stiffening rib, the central axle sleeve fixed tray is formed, race and central axle sleeve fixed tray, be that seamless steel pipe is formed by the technique for rolling once-through, the grooved stiffening rib of race inboard fuses by the inwall of prominent welder's skill with race, and the central authorities of central axle sleeve are provided with bearing, and an end of central axle sleeve is provided with the central axle sleeve flange plate, the central axle sleeve flange plate is connected as a single entity by flat welding process and central axle sleeve, and the central axle sleeve fixed tray by riveting process and race one side fuses.
Because that a kind of new steel plate formula sheave of having adopted such scheme, the utility model to provide has is in light weight, the degree of balance good, production technology is simple, cost is low, the characteristics of long service life.
Description of drawings
Fig. 1 is the structural representation of a kind of new steel plate formula of the utility model sheave.
Fig. 2 is a kind of new steel plate formula of the utility model sheave cross-sectional configuration schematic representation.
Embodiment:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 a kind of new steel plate formula sheave shown in Figure 2 is made up of race 1, central axle sleeve flange plate 2, central axle sleeve 3, bearing 4, rivet 5, grooved stiffening rib 6, central axle sleeve fixed tray 7, central axle sleeve flange plate 2 is connected as a single entity by flat welding process and central axle sleeve 3, central axle sleeve fixed tray 7 by rivet and race side fuses, and the central authorities of central axle sleeve 3 stud with bearing 4.
