Abstract
The utility model relates to an automatic power-off device for a chain transmission case, which comprises a chain transmission case body. An angular displacement type sensor is arranged between two teeth of a gear in the chain transmission case body, a controller is arranged outside the chain transmission case body, and the angular displacement type sensor, the controller and a motor are connected in series. The automatic power-off device is capable of timely stopping the motor to rotate when a chain is broken, and thereby dangerous accidents can be avoided, and damages to a machine can be reduced.
Description
Technical field
The utility model is a kind ofly can detect the device whether chain disconnects, especially a kind of chain transmission case auto-power-off device.
Background technique
At present, as everyone knows we usually the chain in the machine can be because a variety of causes disconnects in process of production, but owing to can not in time find not only to damage the generation that machine also causes peril sometimes.
The model utility content
In order to overcome the shortcoming that the machine chain disconnects fragile machine or causes peril, the utility model provides a kind of chain transmission case auto-power-off device, and this chain transmission case auto-power-off device is easy to use, practical.
The technological scheme that its technical problem that solves the utility model adopts is, this chain transmission case auto-power-off device has a chain transmission case apparatus body, between intrinsic gear two teeth of chain transmission case apparatus, be provided with an angular displacement formula sensor, be provided with a controller outside chain transmission case apparatus body, angular displacement formula sensor and controller, motor are connected in the circuit.
The beneficial effects of the utility model are, the automatic case auto-power-off device of this chain can in time stop motor rotation when chain is disconnected, have avoided the generation of peril also to reduce infringement to machine.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is an electrical schematic diagram of the present utility model.
Among the figure, 1. controller, 2. gear, 3. contact, 4. angular displacement formula sensor, 5. chain, 6. transmission case device body 7. motors.
Embodiment
In the drawings, this chain transmission case auto-power-off device has a chain transmission case apparatus body 6, be provided with an angular displacement formula sensor 4 between 2 liang of teeth of gear in chain transmission case apparatus body 6, outside chain transmission case apparatus body 6, be provided with a controller 1, angular displacement formula sensor 4 is connected in the circuit with controller 1, motor 7, when chain 5 breaks, the contact 3 of angular displacement formula sensor 4 falls into gear grooved, angular displacement formula sensor 4 detects signal and passes to controller 1, controller 1 disconnecting circuit, motor 6 shuts down.
In the drawings, there is matured product to bring on controller 1 and angular displacement formula sensor 4 markets to install and gets final product.
