Abstract
The invention discloses a worm gear bevel gear differential device reducer which comprises a box body, worm and gear groups and a spindle. The spindle is supported in the box body. The reducer further comprises a rotating arm and more than one bevel gear. The rotating arm is sleeved on the spindle through a key, and more than one bevel gear is sleeved onto the rotating arm through a bearing. The worm and gear groups comprise a left worm gear, a right worm gear, a left worm and a right worm. The left worm and the right worm are meshed with the left worm gear and the right worm gear which are sleeved on the spindle on two sides of the rotating arm through bearings, and the left worm gear and the right worm gear are both meshed with more than one bevel gear. The left worm and gear group and the right worm and gear group are meshed with the bevel gears to enable the bevel gears to rotate and revolve to drive the spindle to output through the rotating arm. The reducer is compact in structure, small in size, high in transfer power, large in torque and large in load bearing, the left worm and gear group and the right worm and gear group can be switched in work, and the reducer is small in working abrasion and long in service life.
Description
Technical field
The present invention relates to a kind of speed reducer, relate in particular to a kind of worm gear bevel gear differential device speed reducer.
Background technique
Speed reducer has deceleration and increases torque functions, is applied in the conversion equipment of speed and moment of torsion, therefore in the transmission system of various machinery, can see its trace.At some, speed reducer structure and reduction speed ratio are required to strict occasion, the superiority ultra-traditional gear reduction unit far away of worm-gear speed reducer, worm-gear speed reducer reduction speed ratio is larger, when worm-gear speed reducer work, worm screw is filing worm gear ceaselessly, makes worm gear produce wearing and tearing, after long-term use, worm gear wearing and tearing are large, have a strong impact on working life.
Summary of the invention
In order to solve deficiency of the prior art, the invention provides a kind of compact structure, can effectively reduce worm gear wearing and tearing, the worm gear bevel gear differential device speed reducer increasing the service life.
The technical solution adopted in the present invention is: a kind of worm gear bevel gear differential device speed reducer, comprise casing, worm and gear group and main shaft, described main shaft supporting is in casing, also comprise a pivoted arm and an above umbrella gear, described pivoted arm is socketed on main shaft through key, and an above umbrella gear is connected on pivoted arm through bearing housing; Described worm and gear group comprises left and right worm gear and left and right worm screw, and left and right worm screw engages respectively left and right worm gear, and left and right worm gear is connected on the main shaft of pivoted arm both sides through bearing housing respectively, and left and right worm gear all engages an above umbrella gear.
Wherein, a described above umbrella gear is connected on pivoted arm and evenly arranges around main shaft through bearing housing.
Wherein, on described pivoted arm, be socketed with two umbrella gear around main shaft symmetry.
Revolution when the present invention adopts the common meshing bevel gear of left and right worm and gear group to make umbrella gear rotation, thereby drive main shaft output through pivoted arm, its compact structure, volume is little, transmitted power is large, moment of torsion is large, carrying is large., the changeable work of left and right worm and gear group, speed reducer service wear is little, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of worm gear bevel gear differential device speed reducer of the present invention.
In figure: 1-casing; 2-main shaft; 3-pivoted arm; 4-umbrella gear; The left worm gear of 5-; The left worm screw of 6-; The right worm gear of 7-; The right worm screw of 8-.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Shown in Fig. 1, a kind of worm gear bevel gear differential device speed reducer, comprises casing 1, main shaft 2, pivoted arm 3, umbrella gear 4, left worm gear 5, left worm screw 6, right worm gear 7 and right worm screw 8.Main shaft 2 is supported in casing 1, on main shaft 2, is socketed a pivoted arm 3 through key, and the two ends of pivoted arm 3 are arranged with two umbrella gear 4; Left and right worm gear 5,7 is connected on the main shaft 2 of pivoted arm 3 both sides through bearing housing respectively, and left and right worm screw 6,8 engages respectively left and right worm gear 5,7, and left and right worm gear 5,7 all engages two umbrella gear 4.
Further instruction: a kind of worm gear bevel gear differential device speed reducer, comprise casing, worm and gear group and main shaft, described main shaft supporting is in casing, also comprise a pivoted arm and an above umbrella gear, described pivoted arm is socketed on main shaft through key, and an above umbrella gear is connected on pivoted arm through bearing housing; Described worm and gear group comprises left and right worm gear and left and right worm screw, and left and right worm screw engages respectively left and right worm gear, and left and right worm gear is connected on the main shaft of pivoted arm both sides through bearing housing respectively, and left and right worm gear all engages an above umbrella gear.
Wherein, a described above umbrella gear is connected on pivoted arm and evenly arranges around main shaft through bearing housing.
Wherein, on described pivoted arm, be socketed with two umbrella gear around main shaft symmetry.
When speed reducer work, motor is taken over a worm screw, when left worm screw input, left worm gear rotates around the spindle, and above umbrella gear of left worm gear engagement also drives its rotation, because right worm gear and right worm screw are not worked, the self-locking performance of right worm gear, umbrella gear cannot drive right worm gear rotation, therefore in umbrella gear rotation, revolves round the sun again around main shaft, umbrella gear revolution drives pivoted arm to rotate around the spindle, thereby realizes main shaft output; In the time of right worm screw input, working state is contrary with above-mentioned left worm screw input.Left and right worm and gear group can alternation, avoids independent worm and gear group leader phase service wear seriously to cause damaging, and worm gear long service life, reduces user cost.
Revolution when the present invention adopts the common meshing bevel gear of left and right worm and gear group to make umbrella gear rotation, thereby drive main shaft output through pivoted arm, its compact structure, volume is little, transmitted power is large, moment of torsion is large, carrying is large., the changeable work of left and right worm and gear group, speed reducer service wear is little, long service life.
Finally it should be noted that: above embodiment is only in order to illustrate the present invention and unrestricted technological scheme described in the invention; Therefore, although this specification has been described in detail the present invention with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the present invention; And all do not depart from technological scheme and the improvement thereof of the spirit and scope of the present invention, it all should be encompassed in claim scope of the present invention.
