Abstract
The utility model discloses a limit transmission pinion for a roller shutter, comprising a transmission shaft. The limit transmission pinion for the roller shutter is characterized in that the transmission shaft body is in an equilateral hexagonal shape; a cylinder sleeve is arranged outside the shaft body; a circular bump is arranged at the front end of the transmission shaft; and gear teeth are arranged on the surface of the bump. The utility model can enhance the driving stability, improves the matching precision of parts of the roller shutter, prolongs the service life, is simple in structure and is convenient to install and use.
Description
Technical field
The utility model belongs to a kind of gear, specifically is a kind of roller shutter limiting drive pinion.
Background technology
In the production of roller shutter, be positioned at spacing drive lead screw and be used spacing travelling gear, existing such gear structure is had nothing in common with each other, but there is the bad problem of spacing fixed effect always, causes transmission stability poor, in use tend to occur the shake or the skew of transmission, reduced the homework precision of component, strengthen roller shutter lifting resistance, not only increased energy consumption, but also had influence on the application life of parts.
The utility model content
The purpose of this utility model provides a kind of roller shutter limiting drive pinion, can strengthen stability of transmission, improves the precision that each parts of roller shutter cooperate, and increases the service life.
The technical solution of the utility model is as follows:
A kind of roller shutter limiting drive pinion includes power transmission shaft, it is characterized in that described transmission shafts as equilateral hexagon, and axle body has jacket casing outward, and the power transmission shaft front end has circular protrusions, and convex surfaces has the gear teeth.
The utility model has adopted cooperating of hexagon axle body and jacket casing, can strengthen stability of transmission, improves the precision that each parts of roller shutter cooperate, and has saved power consumption, has prolonged the application life of each parts, and simple in structure, install and use all comparatively convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of roller shutter limiting drive pinion includes power transmission shaft 1, it is characterized in that described power transmission shaft 1 axle body 2 is equilateral hexagon, has jacket casing 3, power transmission shaft 1 front end that circular protrusions 4 is arranged outside the axle body 2, and there are the gear teeth 5 on protruding 4 surfaces.
Claims (1)
