Abstract
The utility model provides a be applied to seal structure of 100 type reduction gears, including worm axle, speed reduction box and worm wheel, wherein, the top of worm axle is provided with ring flange on the worm, and the bottom is provided with worm lower flange dish, simultaneously, the worm wheel is provided with and directly links the end cover. Owing to adopted above -mentioned technique, the utility model discloses a lubricated mode of oil bath, improved the lubricated efficiency of reduction gear greatly, improved worm gear's heat dissipation situation simultaneously, just so improved the transmission efficiency of 100 type reduction gears, increased output torque to the life -span of reduction gear has been improved.
Description
Technical field
The utility model relates to electric actuator field, particularly relates to a kind of sealing configuration being applied to 100 type speed reducers.
Background technique
At present, the moment delivery efficiency of the retarder single head of actuator is between 30%-35%, and under many circumstances, its lubricating system mainly adopts the mode of grease lubrication.At low speed with when infrequently using, the heat that the relative sliding of worm and worm wheel produces can't cause the viscosity of grease to reduce, usage requirement can be met under normal circumstances, but in some cases, the relative sliding velocity of worm and gear is higher, and running time is longer, result in lubricant grease viscosity and be lowered into liquid, although can grease be added when worm and gear is safeguarded, if but the sealability of reduction case is bad, leakage of oil can be caused to produce, this can cause the lubrication of equipment and heat dissipating state to degenerate, retarder worm and gear is engaged and is in dry condition, the retarder life-span is caused greatly to shorten.
Model utility content
In order to solve the problem, the utility model provides a kind of sealing configuration being applied to 100 type speed reducers, have employed the mode of bath lubrication, substantially improve the efficiency of retarder lubrication, improve the heat dissipating state of worm and gear simultaneously, which improves the transmission efficiency of 100 type speed reducers, add output torque, and improve the life-span of retarder.
Above-mentioned a kind of sealing configuration being applied to 100 type speed reducers, comprise worm shaft, deceleration box and worm gear, the top of described worm shaft is provided with worm screw upper flange plate, and the bottom of described worm shaft is provided with worm screw lower flange, and described worm gear is provided with direct-connected end cap.
In said structure, described worm gear is also sealed by outside framework oil seal.
Advantage of the present utility model and beneficial effect are:
1, have employed the mode of oil lubrication, substantially improve lubricating efficiency, improve the efficiency of heat radiation, 100 type speed reducers that simply common 100 type speed reducers can be replaced with improvement can improve output torque more than 1 times, make the life-span of worm and gear improve simultaneously.
2, improve sealing configuration, after making lubricant oil add, in the Life cycle of retarder, do not need to safeguard.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of sealing configuration in the utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, the utility model describes a kind of sealing configuration being applied to 100 type speed reducers, comprises worm shaft, deceleration box 2 and worm gear.
Wherein, the top of worm shaft is provided with worm screw upper flange plate 1, and bottom is provided with worm screw lower flange 3, thus utilizes two flange plate all to be sealed at the two ends up and down of worm-wheel shaft.
Meanwhile, be provided with direct-connected end cap 4 at worm wheel surface, thus play better sealing effect.
Preferably, described worm gear is also sealed by outside framework oil seal.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
1. one kind is applied to the sealing configuration of 100 type speed reducers, comprise worm shaft, deceleration box and worm gear, it is characterized in that, the top of described worm shaft is provided with worm screw upper flange plate, the bottom of described worm shaft is provided with worm screw lower flange, and described worm gear is provided with direct-connected end cap.
2. a kind of sealing configuration being applied to 100 type speed reducers as claimed in claim 1, it is characterized in that, described worm gear is also sealed by outside framework oil seal.
