Description
Technical field
The utility model belongs to bearing lubrication technical field, is specifically related to the lubricating structure being installed on the bearing at worm screw two ends in a kind of bearing lubrication structure being installed on speed reducer on building hoist, particularly Worm upper speed reducer.
Background technique
As shown in Figure 1, the existing worm reduction box be installed on building hoist is the below that worm screw is positioned at worm gear mostly, and it comprises casing 4, worm shaft 5, worm-wheel shaft 9, worm gear 10.Described worm shaft 5 is the integral middle of length direction or partial installation worm screw 501.The two ends of worm shaft 5 length direction are installed on the bottom of casing 4 short transverse rotationally respectively by clutch shaft bearing 6 and the second bearing 2 ', described clutch shaft bearing 6 and the second bearing 2 ' are pressed against on the axle rank of worm shaft 5 respectively by motor flange 7 and end cap 1, to realize the axially locating of worm shaft 5.One end of described casing 4 is provided with motor (not shown) by motor flange 7, and worm shaft 5 extends near the termination of this motor flange 7 one end outside casing 4 and is connected with the transmission shaft (not shown) of motor.Worm-wheel shaft 9 is by rolling bearing hub setting in the top of casing 4 short transverse, and the axially middle sheathed worm gear 10 of worm-wheel shaft 9, described worm gear 10 engages each other transmission with the worm screw 501 on worm shaft 5.Described motor flange 7 and end cap 1 all possess oil sealing base, are provided with the first oil sealing 8 in the oil sealing base of motor flange 7, are provided with the second oil sealing 11 in the oil sealing base of end cap 1.The first described oil sealing 8 and the second oil sealing 11 are set with the two ends in worm shaft 5 length direction, for sealing the lubricant oil in speed reducer.In said structure, when oil sealing produces wearing and tearing, there will be oil leakage phenomenon; Or when worm shaft 5 forms groove because of wearing and tearing, even if more renew oil seals, still can there is leakage of oil in oil sealing place; Or the worm shaft end of mounted motor can produce amount of deflection, cause oil sealing sealing not tight and produce oil leakage phenomenon; In addition, the most outdoor work of building hoist, moisture, dust, abrasive dust are large on the impact of oil sealing, and especially in the summer of high temperature sweltering heat, the bad border that works is severe, and the possibility of oil sealing generation leakage of oil is larger.As can be seen here, the requirement of building hoist speed reducer to oil sealing of worm screw underneath type is higher; Even if but adopt the structure that worm screw is put, to lubricate the bearing at worm shaft two ends too, if employing grease lubrication, because the stability of lubricating grease can be deteriorated by the factor such as high temperature bad border and High Rotation Speed affects, cause bearing wear and cause the problems such as vibration, noise, greatly reduce bearing life, therefore need frequently to change lubricating grease in lift using process.The replacing of lubricating grease, need the pipeline that is equipped with supply and discharges lubricating grease and collect the trap of used lubricating grease, cost is high, structural design and regular maintenance more loaded down with trivial details.Therefore, the bearing at the worm shaft two ends in Worm upper speed reducer preferably adopts lubricant oil to lubricate, circulating by lubricant oil, can with heats a large amount of around bearing running, and can impurity be washed away, but because lubricant oil has good mobility, therefore need to provide a kind of and there is the good bearing lubrication structure protecting functional oil, to ensure that lubricant oil can cyclically be transported in bearing part.
In view of above-mentioned prior art, the applicant has done useful design, and technological scheme described below produces under this background.
