Abstract
The utility model discloses a driving shaft safety protection device which comprises the following components: a motor shaft (1), a gear (2), an elastic member (6), a steel ball (3) and a spring (4). The gear (2) is sleeved on the motor shaft (1). The steel ball (3) is equipped in a groove (7) of the gear (2). The elastic member (6) is equipped on the motor shaft (1). The spring (4) is equipped on the elastic member (6). The steel ball (3) contacts with the spring (4) on the elastic member (6). According to the driving shaft safety protection device, the groove of the gear is disengaged from the steel ball which is squeezed into the spring when overload occurs, the motor performs idle running and the motor can be protected.
Description
Technical field
The utility model relates to a kind of driving shaft safety protection device.
Background technique
In the existing technology, because the driving shaft rotating speed when very fast, phenomenon usually can occur transshipping, at this moment situations such as burn-down of electric motor appear easily making.
The model utility content
The purpose of the utility model provides a kind of driving shaft safety protection device.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of driving shaft safety protection device; Comprise motor shaft (1), gear (2), elastomer (6), steel ball (3) and spring (4); Said gear (2) is sleeved on the motor shaft (1); Said steel ball (3) is installed in the grooving (7) of gear (2); Elastomer (6) is installed on the motor shaft (1), and spring (4) is installed on the elastomer (6), and steel ball (3) contacts with spring (4) on the elastomer (6).
Said elastomer (6) is installed on the motor shaft (1) through key (5).
A kind of driving shaft safety protection device of the utility model, when overload, the grooving of gear is clamp-oned steel ball disengaging grooving in the spring with steel ball, and motor idle running can be protected motor.
Description of drawings
Fig. 1 is the structural representation of a kind of driving shaft safety protection device of the utility model.
Among the figure: 1, motor shaft; 2, gear; 3, steel ball; 4, spring; 5, key; 6, elastomer; 7, grooving.
Embodiment
