In the embodiment of the invention, when the rotating shaft 12 of the speed reducer body 1 rotates, the pushing unit 3 is started, and the pushing unit 3 can drive the self-lubricating unit 2 through the oil quantity adjusting unit 4 to spray oil to a gap between the rotating shaft 12 and the flange 11, so that the rotating shaft 12 can be cooled and lubricated. When the amount of the lubricating oil sprayed out of the self-lubricating unit 2 needs to be regulated, the rotation radius of the oil amount regulating unit 4 can be regulated by rotating the oil amount regulating unit 4, so that the amount of the lubricating oil sprayed out of the self-lubricating unit 2 at one time can be regulated. The excessive lubrication oil is prevented from flowing out of the clearance between the lubrication cylinder 21 and the piston or burning at high temperature to form carbon deposit. And the pushing unit 3 can also adjust the quantity of the lubricating oil sprayed out of the lubricating hole 27 during working, so that the use is more convenient. When the pushing unit 3 makes the self-lubricating unit 2 spray oil, the steering unit 5 can drive the self-lubricating unit 2 to alternately rotate at the moment, so that the uniformity of the surface lubrication of the rotating shaft 12 is improved. When the pushing unit 3 makes the self-lubricating unit 2 return oil, the steering unit 5 can drive the self-lubricating unit 2 to intermittently stay at this time, so that the oil adhered to the surface of the rotating shaft 12 can stably flow back into the self-lubricating unit 2.
In one embodiment of the present invention, as shown in fig. 1 and 3, the self-lubricating unit 2 includes a lubricating cylinder 21 fixed to a side surface of the flange 11, a first check valve 22 and a second check valve 23 are surface-mounted, and a sealing cap 211 is mounted at an end of the lubricating cylinder 21; a piston rod 24 slidably connected within the lubrication cylinder 21, and a piston is mounted to an end of the piston rod 24, the piston being slidably connected within the lubrication cylinder 21; the lubrication ring 26 is rotatably connected to the surface of the flange 11, the rotation shaft 12 penetrates through the lubrication ring 26, and lubrication holes 27 are formed in the surface of the lubrication ring 26; the oil inlet pipe 25 is communicated with the lubrication ring 26 through the first check valve 22.

The sprayed lubricating oil enters a gap between the rotating shaft 12 and the flange 11, and plays roles in cooling and lubricating the rotating shaft 12.
And the second check valve 23 and the lubrication ring 26 can be communicated by adopting an oil return pipe 231, so that the lubrication oil adhered to the surface of the rotating shaft 12 can flow back into the lubrication ring 26 again through the lubrication holes 27. When the piston slides upwards in the lubrication cylinder 21, the second one-way valve 23 is opened, and the first one-way valve 22 is closed, so that the lubrication oil in the lubrication ring 26 can enter the lubrication cylinder 21 again through the oil return pipe 231 and the second one-way valve 23 under the pushing of air pressure due to the fact that the pressure in the lubrication cylinder 21 is reduced at the moment, and recovery of the lubrication oil is completed.
A sealing plate may be further installed in the self-lubricating unit 2, the sealing plate is installed at the end side of the lubricating ring 26, and the rotating shaft 12 is rotatably connected in the sealing plate. The sealing plate is closely contacted with the side surface of the end part of the lubrication ring 26, and can play a role in sealing the lubrication oil sprayed out of the lubrication holes 27, so that the phenomenon of waste caused by outflow of the lubrication oil on the surface of the rotating shaft 12 is prevented.
In one embodiment of the present invention, as shown in fig. 2 and 4, the pushing unit 3 includes a device box 31 fixed to the flange 11, and a driving motor 32 is installed at a side thereof; a rotating disk 33 rotatably connected to the surface of the device box 31, and the rotating disk 33 is connected to the output end of the driving motor 32; the fixed frame 34 is connected to the surface of the rotating disc 33, and the oil quantity adjusting unit 4 is connected inside the fixed frame in a sliding manner; a connecting rod 35 having one end hinged to the end of the piston rod 24 and the other end hinged to the oil amount adjusting unit 4.
The driving motor 32 is started, the output end of the driving motor 32 can drive the rotating disc 33 to rotate on the surface of the device box 31, and the rotating disc 33 can drive the oil quantity adjusting unit 4 to synchronously rotate through the fixing frame 34 when rotating, so that the oil quantity adjusting unit 4 can drive the piston rod 24 to alternately slide in a reciprocating manner in the lubrication cylinder 21 through connection with the connecting rod 35 in the rotating process, and further the piston rod 24 can drive the piston to alternately slide in a reciprocating manner in the lubrication cylinder 21. And then the lubricating oil sprayed out of the self-lubricating unit 2 enters the gap between the rotating shaft 12 and the flange 11, and the cooling and lubricating effects on the rotating shaft 12 are achieved.
The pushing unit 3 may also be replaced by an electric telescopic rod, where the electric telescopic rod is installed on the device box 31, and the end of the electric telescopic rod is connected with the piston rod 24, so that the piston rod 24 is conveniently driven to slide in the lubrication cylinder 21 in a reciprocating and alternating manner, which is not limited only herein.
In one embodiment of the present invention, as shown in fig. 4 and 5, the oil amount adjusting unit 4 includes a transmission rod 41 rotatably connected to the inside of the fixed frame 34, and a sliding member 42 is screwed to the surface of the transmission rod, and the sliding member 42 is slidably connected to the inside of the fixed frame 34; a rotating post 43 rotatably coupled to the inside of the slider 42, the surface being hinged to the end of the piston rod 24 through a connecting rod 35; a first bevel gear 44 installed at an end of the transmission rod 41; the adjusting lever 45 is rotatably connected to the rotating disk 33, and a second bevel gear 46 is mounted on the surface of the adjusting lever, and the second bevel gear 46 is engaged with the first bevel gear 44.
In the process that the rotating disc 33 drives the fixing frame 34 to rotate, the fixing frame 34 can drive the rotating column 43 to synchronously rotate through the sliding piece 42 in the fixing frame, so that the rotating column 43 can drive the piston rod 24 to alternately slide in a reciprocating manner in the lubrication cylinder 21 through connection with the connecting rod 35, and further the piston rod 24 drives the piston to alternately slide in the reciprocating manner in the lubrication cylinder 21. And then the lubricating oil sprayed out of the self-lubricating unit 2 enters the gap between the rotating shaft 12 and the flange 11, and the cooling and lubricating effects on the rotating shaft 12 are achieved.
When the amount of the lubricating oil sprayed out of the lubricating hole 27 needs to be regulated, the regulating rod 45 is rotated, the regulating rod 45 can rotate on the rotating disc 33, and the regulating rod 45 can drive the second bevel gear 46 on the surface of the regulating rod to rotate, so that the second bevel gear 46 can drive the transmission rod 41 to rotate in the fixed frame 34 through connection with the first bevel gear 44, the sliding piece 42 can slide in the fixed frame 34 under the action of the transmission rod 41, and the sliding piece 42 can drive the rotating column 43 on the surface of the sliding piece to synchronously slide during sliding, so that the rotating radius of the rotating column 43 can be regulated.
When the rotation radius of the rotation column 43 changes, the distance that the rotation column 43 drives the piston rod 24 to slide in the lubrication cylinder 21 through the connecting rod 35 also changes, so that the sliding position of the piston in the lubrication cylinder 21 can be adjusted, and the amount of the lubricating oil sprayed out of the lubrication hole 27 at one time can be adjusted. Thereby, the rotating shaft 12 is cooled and lubricated, and the phenomenon that excessive lubricating oil flows out from a gap between the lubricating cylinder 21 and the piston or burns at high temperature to form carbon deposit is avoided.
Since the adjustment lever 45 is at the center position of the rotating disk 33, the position of the adjustment lever 45 is fixed and unchanged, and the rotating disk 33 is normally rotated at a low speed, even when the rotating disk 33 is in operation rotation, the rotational adjustment of the adjustment lever 45 can be performed by the side position of the rotating disk 33. So that the pushing unit 3 can also adjust the quantity of the lubricating oil sprayed from the lubricating hole 27 during working, and the use is more convenient.
The adjusting rod 45 in the oil amount adjusting unit 4 can also penetrate to the other side of the rotating disc 33, and the output end of the driving motor 32 is connected with the rotating disc 33 through the tripod, so that the interference between the output end of the driving motor 32 and the adjusting rod 45 can be prevented, and the adjusting rod 45 can be rotationally adjusted through the other side of the rotating disc 33.

When the rotating column 57 slides to the end of the arc-shaped chute frame 54, the arc-shaped chute frame 54 can drive the reciprocating rod 52 to rotate on the flange 11 under the action of the rotating column 57, the reciprocating rod 52 can drive the rotating gear 53 on the surface of the reciprocating rod 52 to synchronously rotate in the rotating process, and the rotating gear 53 is meshed with the outer surface of the gear ring 51, so that the gear ring 51 can rotate on the surface of the flange 11 under the action of the rotating gear 53, and the gear ring 51 can drive the lubrication holes 27 on the surface of the gear ring 51 to synchronously rotate through the lubrication ring 26 during rotation, so that the positions of the lubrication holes 27 change, lubrication can be carried out on the periphery of the rotating shaft 12, partial positions of the rotating shaft 12 are prevented from not being lubricated, and the uniformity of surface lubrication of the rotating shaft 12 is improved.
In the process that the rotating column 57 drives the reciprocating rod 52 to rotate on the flange 11 through the arc-shaped chute frame 54, the rotating column 57 slides in the arc-shaped chute frame 54 until the rotating column 57 slides to a certain position in the middle of the arc-shaped chute frame 54, at the moment, the arc-shaped chute frame 54 can drive the reciprocating rod 52 to reversely rotate on the flange 11 under the action of the rotating column 57 until the circle center of the arc-shaped chute frame 54 rotates to the position of the rotating rod 55 again, so that the rotating column 57 can slide in the arc-shaped chute frame 54 again, and at the same time, the position of the arc-shaped chute frame 54 cannot change.

And the output end specifications of the rotation lever 55 and the drive motor 32 are identical, the rotation speeds of the rotation lever 55 and the rotation disk 33 (pushing unit 3) are identical. Simultaneously, when the rotating disc 33 drives the piston rod 24 to slide downwards in the lubricating cylinder 21 through the oil quantity adjusting unit 4, the rotating column 57 can drive the reciprocating rod 52 to alternately rotate on the flange 11 through the arc-shaped chute frame 54; when the rotary disk 33 drives the piston rod 24 to slide upward in the lubrication cylinder 21 by the oil amount adjusting unit 4, the rotary column 57 slides inside the arc chute frame 54.
So when the pushing unit 3 makes the self-lubricating unit 2 drive the lubrication holes 27 on the surface of the lubrication ring 26 to spray oil, the rotating rod 55 can drive the lubrication ring 26 to alternately rotate through the steering unit 5, so that the uniformity of lubrication on the surface of the rotating shaft 12 is improved. When the pushing unit 3 makes the self-lubricating unit 2 drive the lubrication holes 27 on the surface of the lubrication ring 26 to return oil, the rotating rod 55 drives the lubrication ring 26 to intermittently stay through the steering unit 5, so that the oil adhered on the surface of the rotating shaft 12 can stably flow back into the lubrication ring 26 through the lubrication holes 27, the lubrication oil in the lubrication ring 26 is prevented from diffusing to four groups on the inner side of the lubrication ring 26 under the action of centrifugal force when the lubrication ring 26 rotates, and the effect that the lubrication oil returns to the lubrication cylinder 21 through the oil return pipe 231 is affected.
The surface of the rotating column 57 in the steering unit 5 can be provided with a guide wheel, the guide wheel is in rolling connection with the inner wall of the arc-shaped chute frame 54, and the rotating column 57 can stably slide in the arc-shaped chute frame 54 through the guide wheel. The side of gear ring 51 still can fix the reference column, the constant head tank can also be seted up to the side of flange 11, reference column sliding connection is in the constant head tank for the constant head tank can lead spacing to gear ring 51 through the reference column, has improved gear ring 51 at flange 11 surface pivoted stability.
In one embodiment of the present invention, as shown in fig. 3 and 7, an oil amount indicating unit 6 is slidably connected to the inside of the lubrication cylinder 21, and the oil amount indicating unit 6 is used for indicating the oil amount inside the lubrication cylinder 21. Therefore, the oil quantity condition in the lubricating cylinder 21 can be directly observed through the oil quantity indicating unit 6, and timely supplementing of the oil quantity in the lubricating cylinder 21 is facilitated.
In one embodiment of the present invention, as shown in fig. 1 and 2, the oil quantity indicating unit 6 includes a floating plate 61 slidably connected in a sliding groove of the inner wall of the lubrication cylinder 21; the slide bar 62 is connected in the slide groove in a sliding way, and the end part of the slide bar is connected with the floating plate 61; a slide 63 connected to the end of the slide bar 62 remote from the floating plate 61; a varistor 64 mounted on the inner wall of the sliding groove and slidably connected to the surface of the slide 63; the indicator 65 is mounted on the surface of the lubrication cylinder 21, one end of the indicator 65 is electrically connected with the end of the rheostat 64, and the other end is electrically connected with the end of the sliding sheet 63. The indicator gauge 65 is essentially an ammeter. A storage battery can be further installed on the flange 11, and the storage battery is electrically connected with the indicator 65, the rheostat 64 and the sliding sheet 63. Since the battery, the indicator 65, the varistor 64 and the slide 63 are electrically connected in sequence, the magnitude of the current passing through the varistor 64 can be read by the indicator 65.
After the lubricating oil in the oil return pipe 231 flows back into the lubricating cylinder 21 through the second one-way valve 23, the floating plate 61 in the sliding groove on the inner wall of the lubricating cylinder 21 can be lifted under the buoyancy action of the lubricating oil, so that the sliding rod 62 can drive the sliding vane 63 to lift, and the sliding vane 63 can slide on the surface of the rheostat 64. Since the slide 63 moves on the surface of the varistor 64, the current passing through the varistor 64 also changes, so that the oil amount in the lubrication cylinder 21 can be detected by reading the indicator 65, and timely replenishment of the oil amount in the lubrication cylinder 21 is facilitated.
The surface of the sliding sheet 63 in the oil quantity indicating unit 6 can be connected with an elastic column, the other end of the elastic column is provided with a roller, and the roller is in rolling connection with the inner wall of the sliding groove. The sliding sheet 63 can roll on the inner wall of the sliding groove by driving the roller through the elastic column when the sliding sheet 63 is lifted, and the sliding sheet 63 can slide on the surface of the rheostat 64 when sliding, so that the sliding sheet 63 can be closely contacted with the surface of the rheostat 64 under the pushing of the elastic force of the elastic column.
The working principle of the invention is as follows: when the rotating shaft 12 of the speed reducer body 1 rotates, the driving motor 32 is started, the output end of the driving motor 32 can drive the rotating disc 33 to rotate on the surface of the device box 31, and the rotating disc 33 can drive the oil quantity adjusting unit 4 to synchronously rotate through the fixing frame 34 during rotation, so that the oil quantity adjusting unit 4 can drive the piston rod 24 to alternately slide in a reciprocating manner in the lubrication cylinder 21 through connection with the connecting rod 35 during rotation, and the piston rod 24 can drive the piston to alternately slide in the lubrication cylinder 21. The lubricating oil sprayed from the lubricating unit 2 enters a gap between the rotating shaft 12 and the flange 11, and plays roles in cooling and lubricating the rotating shaft 12.
When it is necessary to adjust the amount of lubricating oil discharged from the lubrication holes 27, the rotation radius of the rotation post 43 can be adjusted by rotating the adjustment lever 45. When the rotation radius of the rotation column 43 changes, the distance that the rotation column 43 drives the piston rod 24 to slide in the lubrication cylinder 21 through the connecting rod 35 also changes, so that the sliding position of the piston in the lubrication cylinder 21 can be adjusted, and the amount of the lubricating oil sprayed out of the lubrication hole 27 at one time can be adjusted. Thereby, the rotating shaft 12 is cooled and lubricated, and the phenomenon that excessive lubricating oil flows out from a gap between the lubricating cylinder 21 and the piston or burns at high temperature to form carbon deposit is avoided. And the pushing unit 3 can also adjust the quantity of the lubricating oil sprayed out of the lubricating hole 27 during working, so that the use is more convenient.
When the pushing unit 3 makes the self-lubricating unit 2 drive the lubricating holes 27 on the surface of the lubricating ring 26 to spray oil, the rotating rod 55 can drive the lubricating ring 26 to alternately rotate through the steering unit 5, so that the uniformity of the surface lubrication of the rotating shaft 12 is improved. When the pushing unit 3 makes the self-lubricating unit 2 drive the lubrication holes 27 on the surface of the lubrication ring 26 to return oil, the rotating rod 55 drives the lubrication ring 26 to intermittently stay through the steering unit 5, so that the oil adhered on the surface of the rotating shaft 12 can stably flow back into the lubrication ring 26 through the lubrication holes 27, the lubrication oil in the lubrication ring 26 is prevented from diffusing to four groups on the inner side of the lubrication ring 26 under the action of centrifugal force when the lubrication ring 26 rotates, and the effect that the lubrication oil returns to the lubrication cylinder 21 through the oil return pipe 231 is affected.
