Abstract
The utility model relates to a gear transmission device for the transferring rotary motion, which is suitable for being matched with the portable engineering machinery. The utility model is characterized in that an input gear 2 on an input shaft 1 is engaged with a gear idle 3 which is engaged with a gear 4 connected with a worm screw 5, and the worm screw 5 is engaged with a worm wheel 6 on a worm wheel shaft 8. The utility model has the advantages of small size, light weight, and stable and reliable operating performance; the speed ratio can achieve i=1: 70. The utility model can be matched with the portable engineering machinery.
Description
The utility model relates to the gear drive of conveying rotary motion, is applicable to portable engineering machinery use, in particular for the supporting use of erecting cable erection unit.
At present speed ratio because of only adopting gear transmission, or only adopts the transmission of worm gear brush greater than the speed reducer 45 or more, and all volume greatly and heaviness, the portable engineering machinery of incompatibility, and, all require speed ratio big along with the increasing of portable engineering machinery, volume is little, and lightweight speed reducer is supporting with it.
The purpose of this utility model is to overcome the deficiency of above-mentioned existing device, needs that should be actual, and a kind of compact structure is provided, and volume is little, and is in light weight, and stable and reliable working performance satisfies the speed reducer of the supporting usage requirement of portable engineering machinery.
Reaching of the utility model above-mentioned purpose, the scheme of employing is: input gear 2 in the casing 9 on the input shaft 1 and carrier gear 3 engagements, gear 4 engagements that carrier gear 3 is connected with worm screw 5, the worm gear 6 worm gears engagement on worm screw 5 and the worm-wheel shaft 8.
Be further described below in conjunction with accompanying drawing:
Fig. 1: be the structure sectional view of the utility model speed reducer;
The A-A sectional view of Fig. 2: Fig. 1.
Fig. 1: described the overall structure of the utility model speed reducer, it is by casing, bearing, axle, gear, compositions such as worm and gear, input shafts 1 are connected with input gear 2 by bearing 10,11 in the casing 9, input shaft 1 with import gear 2 and can be processed as an integral body; On the worm screw 5 gear is installed, two ends suit tapered roller bearing 12,13 also is meshed with worm gear 6; Worm-wheel shaft 8 is connected with worm gear 6 by key 7, and bearing set 14,15; Carrier gear 3 on the middle little axle 16 is mutually meshing with input gear 2 and gear 4, it is characterized in that: input gear 2 on the input shaft 1 and carrier gear 3 engagements, gear 4 engagements that carrier gear 3 one worm screws 5 connect, worm gear 6 engagements on worm screw 5 and the worm-wheel shaft 7, input shaft 1 driven gear 2 rotates, and the carrier gear 3 by engagement makes fixedly gear 4 rotations of worm screw one end, thereby drive worm screw 5 worm gear is rotated, and drives worm-wheel shaft 8 output torques.
The utility model speed reducer volume is little, and is in light weight, and speed ratio reaches i=1:70, and stable and reliable working performance satisfies the supporting use of portable engineering machinery.
