Description

Technical Field

[0001] The invention relates to the technical field of reducer lubrication, and more particularly to a reducer capable of providing lubrication self-check prompts. Background Art

[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or actuator. It is widely used in modern machinery.

[0003] Most of the existing reducers are lubricated in order to extend the running-in time of the worm and the wheel set, but the lubrication cannot achieve automatic lubrication and cannot judge the wear condition of the internal worm. In addition, most of the existing worms adopt an integrated design, so that some of the threaded rings are severely worn, resulting in the entire device being unusable, which increases cost waste and makes replacement more difficult, thereby reducing the practicality of the overall device.

[0004] Therefore, in view of this, the inventor, based on his many years of rich experience in design, development and actual production in the relevant industry, has studied and improved the existing structure and defects, and provided a reducer with lubrication self-check prompts, in order to achieve a more practical purpose. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a reducer with lubrication self-check prompt, wherein an oil tank and a lubrication device are arranged to cooperate with a second photoelectric sensor and a third photoelectric sensor. When the transmission ring is slightly worn and needs to be lubricated, a signal is transmitted through the second photoelectric sensor, and the electric telescopic rod is extended out of the lower frame, driving the circular tube and the connecting seat to move downward. At this time, the top of the square groove is connected with the interface pipe, and the oil enters the interior of the circular tube and enters the interior of the lubrication box pad through the connecting pipe. Then, the oil is applied to the surface of the wheel set through a brush and is smeared as the wheel set rotates. In cooperation with the rotation of the transmission ring, lubrication is performed at the corresponding position. At this time, the second reflector blocks the third photoelectric sensor. After a period of time, the signal is fed back to control the electric telescopic rod to retract again, and the lubrication box pad is separated from the top surface of the wheel set. Then, the square groove and the interface pipe are in a closed state. A complete set of sensing structures can be used to lubricate the transmission ring in time after wear and tear. And it can realize automatic lubrication, without the need for staff monitoring, and achieve the effect of self-inspection, thereby achieving the purpose of improving the efficiency of the overall device. A telescopic component is set to cooperate with the first photoelectric sensor. When the degree of wear of the transmission ring is too high and it is about to be unusable, the light signal emitted by the first photoelectric sensor cannot be blocked due to the wear and consumption of the transmission ring, and is transmitted to the first reflector plate, and then reflected back, and converted into an electrical signal to stop the drive motor and make it unable to rotate. Then the threaded tube can be rotated, and the threaded tube is displaced, driving the convex tube to move. During the pushing process, the connecting ring and the embedding rod are driven forward together, and the embedding rod is buckled into the inside of the embedding hole, driving the transmission ring to move forward, and moving to a suitable position (that is, a unit distance of a threaded ring). During the movement, the hydraulic damping ring provides resistance to prevent the sleeve tube from sliding on the surface of the sleeve rod. The surface of the sleeve tube fits on the spherical surface of the rolling ball, and does not affect its subsequent rotation, so as to solve the problems raised in the above-mentioned background technology.

[0018] 2. The present invention sets a telescopic component to cooperate with the first photoelectric sensor. When the transmission ring is too worn and is about to become unusable, the light signal emitted by the first photoelectric sensor cannot be blocked due to the wear and consumption of the transmission ring, and is transmitted to the first reflector plate, and then reflected back, and converted into an electrical signal to stop the drive motor from rotating. Then the threaded tube is rotated, and the threaded tube is displaced, driving the convex tube to move. In the process of pushing, the connecting ring and the embedding rod are driven forward together. The embedding rod is buckled into the inside of the embedding hole, driving the transmission ring forward to move to a suitable position (i.e., a unit distance of the threaded ring). During the movement, the hydraulic damping ring provides resistance to prevent the sleeve tube from sliding on the surface of the sleeve rod. The surface of the sleeve tube fits on the spherical surface of the rolling ball and does not affect its subsequent rotation. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The working principle of the present invention is as follows: by arranging the oil tank 3 and the lubricating device 4 in cooperation with the second photoelectric sensor 17 and the third photoelectric sensor 49, when the transmission ring 59 is slightly worn and needs to be lubricated, the second photoelectric sensor 17 transmits a signal, the electric telescopic rod 42 extends out of the lower frame, drives the circular tube 45 and the connecting seat 46 to move downward, and at this time, the top of the square groove 47 is connected with the interface tube 34, the oil enters the interior of the circular tube 45, and enters the interior of the lubrication box pad 43 through the connecting tube 44, and then passes through the bristle brush on the surface of the wheel group 6, and as the wheel group 6 rotates, the oil enters the inner surface of the lubrication box pad 43, and then passes through the bristle brush on the surface of the wheel group 6.

[0034] By setting the telescopic component 5 to cooperate with the first photoelectric sensor 16, when the transmission ring 59 is too worn to be usable, the light signal emitted by the first photoelectric sensor 16 cannot be blocked due to the wear and tear of the transmission ring 59, and is transmitted to the first reflector 15, and then reflected back, and converted into an electrical signal to stop the drive motor 51 and make it unable to rotate. Then the threaded tube 53 can be rotated, and the threaded tube 53 is displaced, driving the convex tube 54 to move. In the process of pushing, the connecting ring 55 and the embedding rod 56 are driven forward together. The embedding rod 56 is buckled into the inside of the embedding hole 58, driving the transmission ring 59 to move forward to a suitable position, that is, a unit distance of the threaded ring. During the movement, the hydraulic damping ring 5111 provides resistance to prevent the sleeve tube 57 from sliding on the surface of the sleeve rod 510. The surface of the sleeve tube 57 fits on the spherical surface of the rolling ball 5113, which does not affect its subsequent rotation.
