Abstract
The utility model discloses a double worm and gear speed reducer belongs to speed reducer technical field. The utility model aims at providing a be suitable for agriculture operation environment, adopt the double worm and gear speed reducer of two cover turbines and the work of worm mesh mode. Double worm and gear speed reducer, at the wired roller of frame upper shaft connection, in the axle of line roller one end inserted big gearbox, big gearbox passes through the adapter sleeve to be connected with little gearbox, was connected with three tooth worms in the little gearbox of motor shaft income of motor, big gearbox is inside to be four tooth worm mesh on a big turbine and the big axostylus axostyle, and the line roller is coaxial with big turbine, and big axostylus axostyle passes the adapter sleeve and stretches into inside the little gearbox to there are little turbine, little turbine and three tooth worm mesh at the macroaxis rod end fixed mounting of portion. The utility model discloses simple structure, installation convenient to use. Because adopt turbine and worm mesh's mode, the cost obviously reduces to be convenient for change, easily purchase, even ordinary peasant also oneself changes very easily.
Description
Technical field
This utility model belongs to reductor technical field.
Background technology
Reductor is current industry-by-industry Application comparison equipment widely, agricultural machinery is substantially the employing intermeshing structure of spiroid gear, operation it is substantially in the environment that dust storm is more yet with agricultural machinery, so in use worm gear easily entering silt, construction features due to spiroid gear engagement, it not to beat tooth, will be locked, have a strong impact on agricultural operation.
Summary of the invention
The purpose of this utility model is to provide one and is suitable for agricultural operation environment, uses the double worm and gear speed reducer that double set worm gear works with worm engaging mode.
Double worm and gear speed reducer, connects wired roller in frame upper shaft, and the axle of line roller one end inserts in big change speed gear box, and big change speed gear box is connected with little change speed gear box by adapter sleeve, and the motor shaft of motor is connected with three tooth worm screws in stretching into little change speed gear box；Big transmission internal is a big worm gear, and big worm gear and the worm engaging on big axostylus axostyle, line roller is coaxial with big worm gear, and big axostylus axostyle stretches into little transmission internal through adapter sleeve, and is installed with small gear, small gear and three tooth worm engagings in big axle end.
This utility model simple in construction, easy to install.Owing to using the mode of worm gear and worm engaging, cost substantially reduces, and is conveniently replaceable, it is easy to buy, and changes even if common peasant is also easy to oneself.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is this utility model internal drive attachment structure schematic diagram.
Detailed description of the invention
See accompanying drawing Fig. 1-2, double worm and gear speed reducer of the present utility model, wired roller 4 is connected in frame 5 upper shaft, line roller 4 can carry out agricultural pull rope, conveyer belt etc. and use, the axle of line roller 4 one end inserts in big change speed gear box 3, big change speed gear box 3 is connected with little change speed gear box 2 by adapter sleeve 6, and the motor shaft of motor 1 is connected with three tooth worm screws 9 in stretching into little change speed gear box 2；Big change speed gear box 3 is internal is a big worm gear 8, big worm gear 8 engages with the worm screw 7 on big axostylus axostyle 10, line roller 4 is coaxial with big worm gear 8, it is internal that big axostylus axostyle 10 stretches into little change speed gear box 2 through adapter sleeve 6, and it is installed with small gear 11 in big axostylus axostyle 10 end, small gear 11 engages with three tooth worm screws 9, three teeth of three tooth worm screws 9 refer to that three start screw line is parallel, the diameter used due to small gear 11 is less than big worm gear 8, and three tooth worm screws 9 are easy to beat tooth, so, it is designed to three parallel threaded line and is engaged power simultaneously, add intensity.This utility model, by big change speed gear box and the switching of little change speed gear box, reaches the effect of speed change.
