The reduction gear comprises a box body, a box body cover, a coupling, a motor and an alarm device, wherein the alarm device comprises a hollow cover body, a pipe, a floater, an optical sending element, an optical receiving element and an alarm; the hollow cover body is fixed on the box body, the pipe connected with the hollow cover body into a whole is inserted in the box body, the bottom of the pipe is communicated with the box body, the floater is arranged in the pipe, one side of the hollow cover body is provided with the optical sending element, the other side of the hollow cover body is provided with the optical receiving element, and the optical sending element and the optical receiving element are connected with the alarm. A photoelectric effect principle is adopted, a semiconductor circuit and electronic components are used without mechanical contacts, and sensitive elements are not in contact with lubricating fluid without generating chemical reactions, thus the device has the advantages of safety and reliability, high sensitivity, high anti-electromagnetic interference capacity, simple structure, less components, low cost and long service life.
Description
Technical field
The invention belongs to and relate to a kind of speed reducer, refer in particular to a kind of speed reducer with the photoelectric warning device.
Background technique
At present, the speed reducer that adopts on the transmission device of various machinery, usually form by the gear train in casing, Box Cover, the casing, coupling, motor etc., Lubricants in casing or lubricating oil leakage or natural wastage, cause liquid level to descend, when dropping to a certain degree, as untimely oiling, the interior gear wear of cabinet can cause slowing down.So need to adopt when liquid level is reduced to safety margins the device that can in time report to the police, the working life that allows the timely supplemental lubrication liquid of equipment operator improve speed reducer, preventive works accident.
Chinese patent application 03217732.1 discloses " a kind of bearing in reduction gears oil pressure warning unit ", and this alarm is made up of signal input circuit, bleeder circuit, photoelectric isolating circuit, single-chip microcomputer, signal output apparatus.Oil pressure gauge must equippedly be gone up by speed reducer elder generation, uses the electrical contact switch of the signal input circuit connection oil pressure gauge of alarm, and oil pressure just often, the electrical contact switch of oil pressure gauge disconnects, when oil pressure was lower than permitted value, the electric contact closure was touched warning circuit and is sent alarm signal.It adopts single-chip microcomputer, and by internal processes, the level of testing external multi-channel input changes, and is applicable to the situation that a plurality of speed reducers use simultaneously, is generally the precision equipment configuration.For single common speed reducer, the structure relative complex, cost is also than higher.
Summary of the invention
The object of the present invention is to provide a kind of speed reducer, in time replenish brake fluid in order in time to submit the equipment operator to the photoelectric warning device.Main innovation is that the triggering of warning device finished by the lifting action of float.It specifically is to implement like this: a kind of speed reducer with the photoelectric warning device, comprise casing, Box Cover, coupling, motor, warning device, it is characterized in that warning device is by the hollow cover body, conduit, float, light emitting devices, light receiving element, alarm is formed, the hollow cover body is fixed on the casing, the conduit that fuses with the hollow cover body inserts in the casing, the bottom of described conduit is communicated with casing, float is installed in the conduit, hollow cover body one side is provided with light emitting devices, opposite side is provided with light receiving element, and described light emitting devices is connected alarm with the light receiving element circuit.
Light emitting devices of the present invention and light receiving element are formed emission-reception and are paid.When casing is filled with Lubricants, according to law of buoyancy, float will upwards float and block the light wave that light emitting devices sends, make light receiving element can not receive light wave, circuitry is in and opens circuit, when Lubricants leaks or after natural wastage causes liquid level to descend, float also descends, when liquid level is reduced to safety margins, float can not be blocked the light wave that is sent by light emitting devices, and at this moment light receiving element receives light wave, and circuitry is connected, alarm in time gives the alarm, the timely supplemental lubrication liquid of alert device operator.
Alarm of the present invention can be arranged on the hollow cover body, also can be arranged on the casing of speed reducer, can certainly leave the casing of hollow cover body and speed reducer and place, and alarm can be that light is reported to the police or the acoustic alarm device, as tutorial light or buzzer.
The present invention utilizes the photoelectric effect principle, adopts semiconductor circuit and electronic component, does not have mechanical contact, and the not contact lubricated liquid of sensing element can not produce chemical reaction, safe and reliable and sensitive height, and anti-electromagnetic interference capability is strong; This device structure is simple, and element is few, and cost is low, long service life (being projected life 10 to 15 years).
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
A kind of speed reducer with the photoelectric warning device, comprise casing 1, Box Cover 2, coupling 4, motor 5, warning device 3, warning device 3 is by hollow cover body 31, conduit 32, float 33, light emitting devices 34, light receiving element 35, alarm 36 is formed, hollow cover body 31 is fixed on the casing 1, the conduit 32 that fuses with hollow cover body 31 inserts in the casing 1, the bottom of conduit 32 is communicated with casing 1, float 33 is installed in the conduit 32, hollow cover body 31 1 sides are provided with light emitting devices 34, opposite side is provided with light receiving element 35, and light emitting devices 34 is connected alarm 36 with light receiving element 35 circuit.
When casing is filled with Lubricants, according to law of buoyancy, float will upwards float and block the infrared waves that ballistic device sends, make light receiving element can not receive infrared waves, circuitry will be in and open circuit, when the Lubricants leakage or after consumption causes liquid level to descend naturally, float also descends, when liquid level is reduced to safety margins, float can not be blocked the infrared waves that is sent by light emitting devices, at this moment light receiving element will receive light wave, and circuitry will be in closed state, and alarm in time gives the alarm.
Claims (3)
1. speed reducer with the photoelectric warning device, comprise casing, Box Cover, coupling, motor, warning device, it is characterized in that warning device is made up of hollow cover body, conduit, float, light emitting devices, light receiving element, alarm, the hollow cover body is fixed on the casing, the conduit that fuses with the hollow cover body inserts in the casing, the bottom of described conduit is communicated with casing, float is installed in the conduit, hollow cover body one side is provided with light emitting devices, opposite side is provided with light receiving element, and described light emitting devices is connected alarm with the light receiving element circuit.
