Abstract
The invention relates to a double-arm traction-type speed reducer structurally characterized in that a turbine and a turbine shaft are combined together, the internal spur of two bearings of the turbine shaft equals to the width of the turbine, both ends of the turbine shaft are in pyramid shapes, and the pyramid parts at both ends of the turbine shaft are respectively connected with rockers, the other ends of the rockers are fixed on a traction sleeve through the bearings, and the traction sleeve is connected with a traction rod and directly connected with traction operation equipment so as to reduce a replacing device and a space occupied thereby, be convenient to mount and repair and have simple structure.
Description
Affiliated technical field
The present invention relates to a kind of speed reducer, relate in particular to the speed reducer of energy both arms tractive.
Background technique
At present, known worm speed reducer volume is roomy, and turbine shaft has single shaft and two shaft, is cylinder keyway Placement, and turbine and turbine shaft also are cylinder keyway Placement.But a lot of implements need then need be replaced into tractive with rotation by adding set in the operation of narrow space tractive between speed reducer and implement, be not easy because of the space is narrow sometimes to realize.
Summary of the invention
Roomy and can not directly export the deficiency of tractive in order to overcome existing worm speed reducer volume, the invention provides a kind of both arms draw-off type speed reducer, this speed reducer width is narrow, and both sides are the direct needed pulling force of output operation equipment all.
The technical solution adopted for the present invention to solve the technical problems is: turbine and turbine shaft are integrated, distance and turbine width equate in the two bearings of turbine shaft, the side of being, turbine shaft two ends taper, turbine shaft two ends side conical section respectively connects rocking arm; the other end of rocking arm is by bearing fixing tractive cover; the tractive cover connects stayed pole, and stayed pole connects implement.
The invention has the beneficial effects as follows, can be integrated,, reduced displacement apparatus and its shared space, make things convenient for I﹠M by the direct tractive implement of speed reducer by worm gear and turbine shaft, simple in structure.
Description of drawings
Fig. 1 is a cross-sectional view of the present invention.
1. turbines among the figure, 2. turbine shaft, 3. bearing a, 4. square cone, 5. rocking arm, 6. bearing b, 7. tractive cover, 8. bearing pin, 9. stayed pole, 10. worm screw.
Embodiment
Among the figure, turbine (1) is integrated with turbine shaft (2), the distance on the turbine shaft between the two bearings a (3) and the width of turbine equate, turbine shaft two ends side cone (4), fixing rocking arm (5) on side's cone; the rocking arm the other end connects tractive cover (7) by bearing b (6), tractive cover upper pin (8) connects stayed pole (9).The described turbine rotation of worm screw (10) drive, turbine drives described worm-wheel shaft rotation, and worm-wheel shaft drives described rocking arm rotation, and rocking arm rotates described tractive cover, and the described stayed pole of tractive cover drive is done and is seesawed.
Claims (3)
1. both arms draw-off type speed reducer, comprise turbine (1), turbine shaft (2), bearing a (3), it is characterized in that: described turbine and described turbine shaft are linking body structure, turbine shaft two ends side cone (4) structure, on the turbine shaft between the two described bearing a distance equate with the turbine width, the turbine shaft two ends are rocking arm (5) fixedly, and the other end of rocking arm connects tractive cover (7) by bearing b (6), and tractive hollow pin (8) connects stayed pole (9);
2. both arms draw-off type speed reducer according to claim 1 is characterized in that: described rocking arm and described tractive overlap available eccentric bushing and replace;
3. both arms draw-off type speed reducer according to claim 1 is characterized in that: described stayed pole can use chain, rope to replace.
