Abstract

The utility model relates to a small pulley, in particular to a small pulley for oil pumping units. The small pulley comprises a small pulley with a V-belt trough which is matched with a V-belt for use, wherein concave-convex teeth designed by the principle of mesh transmission are formed in the trough, and the radiuses of each concave tooth and each convex tooth are 0.303cm and 0.281cm respectively. The small pulley with simple structure can realize the reciprocating friction and mesh transmissions, thereby saving the production cost and ensuring the smooth and normal production operation.

Description

The small pulley that is used for pumping unit
Technical field
The utility model is a kind of small pulley, particularly a kind of small pulley that is used for pumping unit.
Background technique
The small pulley that is used for pumping unit of the prior art has only a trough of belt, driving belt places in the trough of belt, drive the small pulley rotation by friction driving, run into sleety weather, driving belt skids easily, gnaw the tooth phenomenon, it is damaged that driving belt is taken place, and simultaneously pumping unit worked normally, causes very big loss, to often change driving belt simultaneously, increase working strength of workers.
Chinese patent CN2299168, a kind of belt of oil pumping machine wheel race variation device is disclosed, on the oil-field oil pumper belt pulley, a kind of race that clamps of race modification, it is to serve as that the basis clamps required modification race as required and adopts former race location on the former belt pulley of pumping unit with the former belt pulley of pumping unit, and bolt draws card connection to fix.This utility model patent installs additional on belt wheel and clamps race, can increase frictional force on certain degree, but poor effect, change driving belt that can not be basic gnaw the tooth phenomenon.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of small pulley that has the V-arrangement race is provided, and is provided with shaggy tooth in the groove, and the radius of recessed tooth and double wedge is respectively 0.303cm and 0.281cm.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of small pulley that is used for pumping unit, the small pulley that comprises a V-belt groove is used with V-belt, and the shaggy tooth by the engagement driving principle design is arranged in the groove, the radius of described recessed tooth and double wedge is respectively 0.303cm and 0.281cm, and the angle with the small pulley center of circle between double wedge is 5 °.
As preferably, described shaggy tooth is continuously uniform.
As preferably, described shaggy tooth is a circle-arc tooth, or a kind of in the involute tooth, ellipse tooth, hyperbola tooth, parabola tooth, cycloid tooth.
Therefore, the utility model is simple in structure, and cost of production is saved in friction driving and engagement driving to-and-fro motion, guarantees the normal smoothly operation of producing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as shown in Figure 1, a kind of small pulley that is used for pumping unit, the small pulley 1 that comprises a V-belt groove, be used with V-belt 2, the shaggy tooth 3 by the engagement driving principle design is arranged in the groove, the radius of described recessed tooth 5 and double wedge 4 is respectively 0.303cm and 0.281cm, 4 angles with small pulley 1 center of circle of double wedge are 5 °, shaggy tooth 3 is continuously uniform, and shaggy tooth 3 is circle-arc teeth, or a kind of in the involute tooth, ellipse tooth, hyperbola tooth, parabola tooth, cycloid tooth.
