Abstract
The utility model discloses a hand-operated hoister, the transmission mechanism of which is a planetary gear drive mechanism with teeth difference. A planetary spoke plate is provided with a circular hole; a house is provided with a pillar pin which is provided with a pin bushing; the pillar pin and the circular hole are evenly distributed on a circle with equal radius; the radius difference of the circle and the outer circle of the pin bushing is the distance between the rotating center of an eccentric wheel and the geometric centre of the eccentric wheel; the pillar pin and the pin bushing are inserted into the circle hole. A center wheel and a rope wheel are integrated to be a whole body, wherein, the center wheel is capable of rotating around the axes thereof; the movement can be input from the eccentric wheel and output from the center wheel. The hand-operated hoister has the advantages of simple structure, low requirement for machining precision and high transmission efficiency.
Description
Technical field
The utility model relates to a kind of hand gig, belongs to machinery manufacturing technology field.
Background technology
High-lift operation hanging cradle is applied to the operations such as cleaning, decoration and brushing of external wall, and the lifting of hanging basket realizes by gig.Gig divides hand gig and two kinds of forms of motor hoist, when lifting weight hour adopts hand gig.The transmission device of existing hand gig is a gear difference planetary driving mechanism, and in this mechanism, center gear rotates, satellite gear only with the plane of its axis normal in swing and not around its rotational.Existing control satellite gear only with the plane of its axis normal in swing and not around the mechanism of its rotational, complex structure, the requirement on machining accuracy height, driving efficiency is low.
The utility model content
The technical problems to be solved in the utility model provides a kind of hand gig, solves existing hand gig transmission device complex structure, requirement on machining accuracy height, the shortcoming that driving efficiency is low.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of hand gig, comprise right shell body, left shell, by the main shaft of bearing installation on right shell body and left shell, by the center gear of bearing installation on left shell, the center gear outer rim has grooving, center gear is coaxial with main shaft, be mounted on eccentric wheel on the main shaft by key, by the satellite gear of bearing installation on eccentric wheel, it is characterized in that: 6 straight pins are installed on the right shell body, guide is housed on the straight pin, it is on the circle in the center of circle that straight pin is distributed on the eccentric wheel centre of gration, offer 6 circular holes on the satellite gear disc, it is that the difference of circle hole radius and guide exradius is the distance of eccentric wheel centre of gration and eccentric wheel geometric centre on the circle of radius such as the uniform circle of the center of circle and straight pin that circular hole is distributed on the satellite gear geometric centre.
Adopt the beneficial effect that technique scheme produced to be: to simplify reducer structure, reduced the requirement on machining accuracy of member, reduced loss due to friction, improved driving efficiency.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Wherein, the 1st, left shell, the 2nd, center gear, the 3rd, eccentric wheel, the 4th, right shell body, the 5th, circular hole, the 6th, guide, the 7th, straight pin, the 8th, main shaft, the 9th, satellite gear.
The specific embodiment
Referring to accompanying drawing 1, hand gig of the present utility model, comprise right shell body 4, left shell 1, main shaft 8 by bearing installation on right shell body 4 and left shell 1, center gear 2 by bearing installation on left shell 1, center gear 2 outer rims have grooving, center gear 2 is coaxial with main shaft 8, hand gig also comprise by key be mounted on the main shaft 8 eccentric wheel 3 and by the satellite gear 9 of bearing installation on eccentric wheel 3,6 straight pins 7 are installed on the right shell body 4, guide 6 is housed on the straight pin 7, and it is on the circle in the center of circle that straight pin 7 is distributed on eccentric wheel 3 centre of grations, offers 6 circular holes 5 on satellite gear 9 disc, it is that the difference of circular hole 5 radiuses and guide 6 exradius is the distance of eccentric wheel 3 centre of grations and eccentric wheel 3 geometric centres on the circle of radiuses such as the center of circle and straight pin 7 uniform circles that circular hole 5 is distributed on satellite gear 9 geometric centres.The straight pin 7 that is installed on the right shell body 4 inserts in the circular hole of offering on satellite gear 9 disc 5 together with guide 6, when external force drives eccentric wheel 3 around its centre of gration rotation by main shaft 8, eccentric wheel 3 drives satellite gear 9 and moves together, because the restriction of the straight pin 7 on the right shell body 4, satellite gear 9 can only with the plane of its axis normal in swing, with satellite gear 9 ingear center gears 2 around playing a rotational, the output of will moving.The utility model is hand gig, satellite gear 9 and center gear 2 rotating speeds are low, load is little, for reducing scantling of structure and reducing manufacturing cost, the flank profil of center gear 2 is made of two sections tangent circular arcs, and tooth top partial arc radius is 4 millimeters, and tooth root partial arc radius is 7.5 millimeters, the number of teeth is 20, and tip diameter is 127 millimeters; The external tooth of satellite gear 9 is the columniform pin tooth of band sleeve, and the sleeve outside diameter is 14 millimeters, and tip diameter is 133 millimeters, and the number of teeth is 19.
