Abstract
The utility model relates to a speed reducer, especially, relate to a big velocity ratio high efficiency worm gear speed reducer of totally enclosed machine. It solves speed reducer that prior art exists because sealing performance is not high, and the dust is invaded easily, therefore its transmission efficiency is relatively poor to under big velocity ratio transmission, the intensity of worm wheel does not reach the requirement, and noise that the speed reducer produced is the great technical problem who waits also. The utility model discloses a box (1), box (1) in be equipped with input shaft (2), input shaft has worm (3), the worm is connected with worm wheel (4), output shaft (5) is connected to the worm wheel, the outer end of worm wheel is equipped with sealing member (6), realizes in the sealing member to be equipped with a plurality of bumps (7).
Description
Technical field
The utility model relates to a kind of speed reducer, especially relates to a kind of totally enclosed type large speed ratio high efficiency worm-gear speed reducer.
Background technique
At present, miniature gear speed reducer, the worm-gear speed reducer of being used widely, be subject to volume restriction, its speed ratio is less than normal, and its transmission direction is generally parallel input output and can not meets some existing large speed ratios mini-plant having again vertical-transmission direction to require that slows down and install and use.Chinese patent discloses a kind of double worm gear reducing mechanism (Authorization Notice No.: CN201250880Y), it comprises worm type of reduction gearing, be provided with two worm type of reduction gearings, worm screw on two worm type of reduction gearings is linked together by the coupling of axial rotation adjustable angle, realizes synchronization; Have at least the worm screw two ends of all to stretch out in himself reducer shell in two worm type of reduction gearings, the input shaft of one end as this reducing gear of coupling is not installed on this worm screw; Output shaft on each worm type of reduction gearing is connected to a small gear; With gearwheel engagement driving while of small gear, and using the transmission shaft at gearwheel place as the output shaft of this reducing gear; The two ends of the worm screw of two worm type of reduction gearings all stretch out in the housing of respective retarder itself, two worm type of reduction gearings and respectively connected small gear, there is identical specification respectively, the coupling of the axial rotation adjustable angle used is made up of two half-couplings, one of them half-coupling is uniformly distributed some screws, screw on another half-coupling described in correspondence is provided with the elongated hole of some arcs, is fastenedly connected between two half-couplings by screw.But this speed reducer due to sealability not high, dust easily invades, and therefore its transmission efficiency is poor, and under large speed ratio transmission, the intensity of worm gear does not reach requirement, speed reducer produce noise also larger.
Model utility content
The utility model is to provide a kind of totally enclosed type large speed ratio high efficiency worm-gear speed reducer, its mainly solve speed reducer existing for prior art due to sealability not high, dust easily invades, therefore its transmission efficiency is poor, and under large speed ratio transmission, the intensity of worm gear does not reach requirement, the technical problem of the noise yet larger grade that speed reducer produces.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Totally enclosed type large speed ratio high efficiency worm-gear speed reducer of the present utility model, comprise casing, input shaft is provided with in described casing, input shaft is connected with worm screw, worm screw is connected with worm gear, worm gear connects output shaft, and the outer end of worm gear, worm screw is provided with Sealing, and the inner circle of Sealing is provided with multiple salient point.By Sealing, can ensure speed reducer operationally, dust can not enter into speed reducer inside.Can ensure that whole worm-gear speed reducer runs expeditiously like this.Sealing is that annular is arranged.Inner circle due to Sealing is provided with multiple salient point, and whole speed reducer can be made like this to be full enclosed type.
As preferably, the inwall of described casing is embedded with radiating block, the inner of radiating block is provided with multiple heat radiation lip.Radiating block is inlaid in the internal surface of casing, and radiating block has multiple heat radiation lips of divergence form setting, can increase the area contacted with heat, thus make radiating effect better.
As preferably, the worm-gear tooth root of described worm gear has reinforcing groove, reinforces in groove and is embedded with reinforcing alloy block.The hardness of reinforcing alloy block is higher than the hardness of worm gear itself.So at high temperature, the worm-gear tooth of worm gear also can not forced breakage, and working life is longer.
As preferably, the inwall of described casing is provided with acoustical cotton, and acoustical cotton inside is provided with some cavitys.Cavity in acoustical cotton can absorb noise on the one hand, noise repeatedly can be reflected in cavity, abate the noise.Cavity can also play dust-proof effect on the other hand.
Therefore, the utility model arranges Sealing in speed reducer inside, can ensure that speed reducer runs expeditiously, and utilize salient point that whole speed reducer can be made for full enclosed type, additionally by reinforcing alloy block, can the intensity of strong whole worm gear, simple and reasonable for structure.
