Abstract
The utility model provides a gear reducer's bearing lubricating system, this bearing of lubricating system places the box of reduction gear in, is equipped with first bearing hole and second bearing hole on the tank wall of the interior one side of box, all installs a pair of cover in first bearing hole and the second bearing hole and establishes at the epaxial bearing of gear, and including first oil duct, second oil duct and threaded rod, first oil duct is established at first bearing downtheholely, and the threaded rod stretches into in the first oil duct, on the tank wall between first bearing hole and second bearing hole is established to the second oil duct, and the second oil duct respectively with first bearing hole and second bearing hole intercommunication, the top of two gear shafts all is equipped with the convex shoulder, all is equipped with between epaxial convex shoulder of every gear and the bearing and gets rid of the oil cup. When the gear shaft rotated, the lubricating oil in the first oil duct was driven by the threaded rod and upwards gets into first bearing hole, then got into second bearing hole through the second oil duct, and lubricating oil is stored along the oil cup that gets rid of that sets up down through the bearing overcoat to rotation through getting rid of the oil cup is lubricated the bearing.
Description
Technical field
The utility model relates to retarder technical field, is specifically related to a kind of bearing lubrication system of gear reducer.
Background technique
At present, in mechanical engineering field application widely, wherein, bevel gear, skewed tooth cylindrical gears reduction gear or hypoid gear wheel decelerator are then widely used in the transmission of the machineries such as metallurgy, mine, cement to reducer with hardened tooth surface.Severe due to its working environment, lubrication system directly affects the service behaviour of retarder, and especially at right angle setting situation, the bearing of top can not get sufficient lubrication.Therefore, a kind of lubrication system is needed badly to improve the service behaviour of retarder.
Model utility content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of bearing lubrication system of gear reducer, can lubricate the bearing being vertically mounted on retarder top.
The utility model for the adopted technological scheme that solves the problem is: a kind of bearing lubrication system of gear reducer, this bearing lubrication system is placed in the casing of retarder, in casing, the tank wall of side is provided with the clutch shaft bearing hole and the second bearing hole that vertically arrange, in clutch shaft bearing hole and the second bearing hole, the bearing be set in for a pair on gear shaft is all installed, this bearing lubrication system comprises the first oil duct, second oil duct and threaded stem, the first described oil duct is located in clutch shaft bearing hole, and the two ends up and down of the first oil duct are corresponding concordant with lower edge with the upper edge of two bearings up and down in clutch shaft bearing hole respectively, one end of threaded stem is fixed on cabinet wall, the other end stretches in the first oil duct, the second described oil duct is located on the tank wall between clutch shaft bearing hole and the second bearing hole, and the second oil duct is communicated with the second bearing hole with clutch shaft bearing hole respectively, the top of two gear shafts is equipped with the convex shoulder for placing bearing, is equipped with oil slinger between the convex shoulder on each gear shaft and bearing.
In the utility model, the outer rim of oil slinger is less than the outer rim 3 ~ 5mm of bearing outside.
Preferably, the upper end of the first described oil duct is tapered.
Beneficial effect: in (1), the utility model, when gear shaft rotates, lubricant oil in first oil duct is under centrifugal action, driven by threaded stem and upwards enter clutch shaft bearing hole, then the second bearing hole is entered through the second oil duct, lubricant oil by storing along the oil slinger arranged under bearing outside, and is lubricated bearing by the rotation of oil slinger, and this bearing lubrication system is made up of the first oil duct, the second oil duct, threaded stem and oil slinger.
(2), wherein, threaded stem plays the effect of upwards drawing oil, oil slinger plays oil in reserve, and get rid of to bearing the effect that oil carries out lubricating, the bearing that this bearing lubrication system can meet being vertically mounted on retarder top lubricates, improve retarder service behaviour, the working life of prolonged deceleration device.
(3), use the reducer structure of this bearing lubrication system compact, volume is little, efficiency is high, and transmission stability is good, and gear range is large, high reduction speed ratio, and easy to operate, using effect is good, can Long-Time Service not fragile, be applicable to applying.
Accompanying drawing explanation
