Abstract
The utility model discloses a lubricating device for an input shaft bearing of a speed reducer, belonging to the technical field of speed reducers. The lubricating device is arranged in a body of a gear box of the speed reducer and comprises an oil receiving tank which is fixedly arranged on the body of the gear box, one end of the oil receiving tank is close to a position where an input shaft gear of the speed reducer is meshed with a bull gear, and the other end of the oil receiving tank is close to the inner side of the input shaft bearing. The lubricating device can realize forced lubrication on the input shaft bearing, and prolong the service life of the input shaft bearing, and is widely applied to manufacture and use of the speed reducers.
Description
Technical field
The utility model relates to the retarder technical field, relates in particular to a kind of reducer input shaft bearing-lubricating device.
Background technique
Conventional double reduction gear on the market, bearing of input shaft lubricating system generally are to get rid of the purpose that on bearing, reaches lubricated through the lubricant oil that splashes out in the gear operation process.The retarder that generally uses on the oil field at present mostly is this kind lubricating system, can reach lubricated purpose in the not high place of warming up with temperature of lubricating oil viscosity.But; When input shaft retarder low-speed running or lubricating oil viscosity is higher or temperature very cold the time; Can not splash along with the gear rotation attached to the lubricant oil above the gear, this moment, bearing of input shaft was often owing to long-time unlubricated or lubricated insufficient the damage always.
The model utility content
The utility model technical problem to be solved is: a kind of reducer input shaft bearing-lubricating device is provided, can realizes the pressure lubrication of bearing of input shaft, prolonged the working life of bearing of input shaft.
For solving the problems of the technologies described above; The technological scheme of the utility model is: the reducer input shaft bearing-lubricating device; Be installed in the casing of gear-box of said retarder; Comprise the oil-containing groove on the casing that is fixedly installed in said gear-box, said oil-containing groove one end is near said reducer input shaft gear and gearwheel engaging position, and the other end of said oil-containing groove is near the inboard of said bearing of input shaft.
As a kind of improvement, the casing of said gear-box is provided with the spill port with the intracavity inter-connection of said gear-box, and said spill port is opened on the outside of said bearing of input shaft.
After having adopted technique scheme; The beneficial effect of the utility model is: owing in this space, inboard of input shaft gear and gearwheel engaging position to bearing of input shaft, be provided with oil-containing groove; Bearing of input shaft is caught and flowed to the lubricant oil of extruding during with input shaft gear and gearwheel engagement, makes bearing of input shaft obtain pressure lubrication, no matter when; As long as in the gear-box enough lubricant oil is arranged; Bearing of input shaft just can access lubricated, has avoided bearing of input shaft to hang down the defective that can't obtain lubricating under the situation that perhaps temperature is low at the input shaft rotating speed, has prolonged the working life of bearing of input shaft greatly.
Owing to designed spill port on the casing of gear-box; The feasible lubricant oil that passes bearing of input shaft; Can flow back to the inner chamber of gear-box from the outside of bearing of input shaft; The lubricant oil that flows can be taken away the part heat of bearing of input shaft, avoids that bearing of input shaft is overheated to be burnt, and has further prolonged the working life of bearing of input shaft.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the utility model embodiment's a user mode schematic representation;
Fig. 2 is that schematic representation is looked on the left side of Fig. 1;
Among the figure: 1, gear-box, 2, input shaft, 3, input shaft gear, 4, gearwheel, 5, bearing of input shaft, 6, bearing (ball) cover, 7, oil-containing groove, 8, spill port.
Embodiment
As depicted in figs. 1 and 2; A kind of reducer input shaft bearing-lubricating device is installed in the casing of gear-box 1 of said retarder, comprises the oil-containing groove 7 on the casing that is fixedly installed in said gear-box 1; Traditionally; Oil-containing groove 7 connects a mounting plate, mounting plate through bolt on the casing of gear-box 1, thereby the fixing position of oil-containing groove 7; Input shaft 2 is provided with input shaft gear 3, and oil-containing groove 7 just is arranged on the below of input shaft 2, and said oil-containing groove 7 one ends are near said reducer input shaft gear 3 and gearwheel 4 engaging position; The other end of said oil-containing groove 7 is near the inboard of said bearing of input shaft 5; For the ease of carrying lubricant oil, those skilled in the art can draw easily, and oil-containing groove 7 is lower than the other end near an end of bearing of input shaft 5; Like this, the lubricant oil of receiving can flow to bearing of input shaft 5 more smoothly.
The casing of said gear-box 1 is provided with the spill port 8 with the intracavity inter-connection of said gear-box 1; Said spill port 8 is opened on the outside of said bearing of input shaft 5; Particular location is that the opening of spill port 8 is on the casing of the gear-box 1 between bearing (ball) cover 6 and the bearing of input shaft 5.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the utility model.
Claims (2)
1. reducer input shaft bearing-lubricating device; Be installed in the casing of gear-box of said retarder; It is characterized in that: comprise the oil-containing groove on the casing that is fixedly installed in said gear-box; Said oil-containing groove one end is near said reducer input shaft gear and gearwheel engaging position, and the other end of said oil-containing groove is near the inboard of said bearing of input shaft.
2. reducer input shaft bearing-lubricating device as claimed in claim 1 is characterized in that: the casing of said gear-box is provided with the spill port with the intracavity inter-connection of said gear-box, and said spill port is opened on the outside of said bearing of input shaft.
