Abstract
The utility model relates to a rat cage type wriggling decelerator, particularly a tooth differential planet diversification lever pair transmission mechanism which is formed by the engagement of circular rolling shaft sleeve bodies uniformly distributed on an outer wriggling wheel shell and semicircular arc concave teeth of the outer circumference of an inner wriggling wheel. When an eccentric shaft sleeve is rotated for one circle, after semicircular arc tooth surfaces which are mutually engaged generate extrusion transmission which is radially and tangentially deferred continuously, one tooth pitch is relatively shifted. The utility model has the advantages of flexible design, convenience, regularity, easy manufacture of very large speed ratio, stable motion, no impact, low noise, high transmission precision, slide friction, low temperature rise, high efficiency and long service life. The utility model can be widely applied to the fields of automation control, spaceflight, aviation, traffic, metallurgy, agricultural machines and tools, etc. The utility model is an upgrade product of the existing cycloidal needle wheel decelerator.
Description
Affiliated technical field
The utility model relates to a kind of squirrel-cage shaped wriggling speed reducer.
Squirrel-cage shaped wriggling speed reducer belongs to a differential teeth planetary diversification lever and pays a plurality of circular scrolling sleeve bodies that asymptotic circulation drives the mouse cage annular, makes directly, tangentially to change a kind of mechanical deceleration device of transmission along the semicircle cambered surface.
Background technique
At present to manufacture and design difficulty very big for the known line pin gear speed reducer of wriggling, and the input shaft rotating speed is limited.
Existing wriggling speed reducer exists the circular scrolling medium and wriggles outside and revolve floating the rotation in the semi-circle mark of mouth of wheel, when being subjected to the abrasion gap to become big, will produce the motion oscillatory surge, and permanent running will exist hidden danger for large-scale wriggling speed reducer.
Summary of the invention
To improve wriggling speed reducer performance and existing cycloidal planetary gear speed reducer is carried out technology innovation in order to expand, make to manufacture and design easyly, it is arc toothed not need special precision equipment to process, and helps manufacturing and designing the speed reducer of multiple large speed ratio.Can be applied to fields such as automation control, measurement, space flight, aviation, instrument and apparatus, engineering machinery, communications and transportation, metallurgical mining widely, provide a kind of quick feasible design proposal for cycloidal planetary gear speed reducer renovates.
Description of drawings
Below in conjunction with drawings and Examples squirrel-cage shaped wriggling speed reducer is described further.
Accompanying drawing is a squirrel-cage shaped wriggling speed reducer drive mechanism schematic representation.1. excentric sleeves among the figure, 2. in wriggling wheel, 3. circular scrolling sleeve body, 4. around axis body, 5. outer wriggling hub.
Embodiment
Outer wriggling hub (5) periphery uniform installation circular scrolling sleeve body (3) is formed squirrel-cage shaped cylinder ring gear, in wriggling wheel (2) periphery is uniform lack the semi-circle gear of a tooth pitch than mouse cage shape cylinder ring gear, insert composition one differential teeth planetary structure in the squirrel-cage shaped cylinder ring gear.
Excentric sleeve (1) is rotated a circle by motivational drive, and the uniform semi-circle mark of mouth of interior wriggling wheel (2) periphery is postponed, and lateral extrusion circular scrolling sleeve body (3) makes the outer wriggling hub (5) of mouse cage annular take turns the relative tooth pitch that tangentially rotates with interior wriggling.
Input is same center line with output shaft, does not have the reciprocal transmission of impact, and multiple tooth while engagement driving bearing capacity is strong, transmission accuracy is high, and the rolling friction temperature rise is low, efficient is high, the life-span is long.
Used the internal association rule between circle and the circle, in designing and calculating, eliminated this irrational number of Ratio of the circumference of a circle to its diameter (π), greatly the simplification of degree design, realized that speed reducer manufactures and designs the field technology innovation in the field, make simple and easy to do in addition, general general purpose machine tool all can satisfy the requirement on machining accuracy of squirrel-cage shaped wriggling speed reducer, can effectively reduce manufacture cost with technologies such as injection moulding, powder metallurgy, die casting finish forges.
Claims (1)
- A kind of squirrel-cage shaped wriggling speed reducer is characterized in that: a plurality of circular scrolling sleeve bodies of the uniform installation of the hub of wriggling outward (5) periphery (3) are formed squirrel-cage shaped cylinder ring gear, few tooth pitch of the recessed gear ratio squirrel-cage shaped of semi-circle cylinder ring gear that interior wriggling wheel (2) periphery is uniform, form a differential teeth planetary diversification lever and pay drive mechanism, excentric sleeve (1) rotates a circle, after the work that the semi-circle flank of tooth of interior wriggling wheel (2), circular scrolling sleeve body (3) engagement is postponed continuously directly, tangentially pushes transmission, tooth pitch of relative displacement.
