Description
Technical field
The utility model relates to a kind of involute and draws instrument, and especially a kind of variable circle involute generator, belongs to teaching aid technical field.
Background technology
Involute generator is mainly used in daily teaching, drawing, experiment etc., and conventionally in education, scientific research field is used.Theory of mechanics is as a mechanical basic subject, teacher often replaces involute with circular arc in teaching process, and the shape of involute relies on teacher's experience to draw, and explains abstract, student in study for the production process of involute, change in shape indigestion.When drawing, for the partial enlarged drawing of involute gear, use the circular arc method of substitution cannot embody the involute shape that different basic circles are corresponding.
Summary of the invention
The technical problems to be solved in the utility model is: solve in teaching, drawing, experiment and be difficult to draw exactly involute, the generative process of mechanical principle course middle school student indigestion involute, the problem that is difficult for understanding the involute profile shape under different base radius, provides a kind of variable circle involute generator.This instrument is by basic circle adjustable mechanism is set, thereby the object of circle involute is drawn in realization.
In order to address the above problem, the utility model by the following technical solutions:
A kind of variable circle involute generator, comprise supporting leg, base, guide rail, chassis, longitudinal bevel gear, horizontal bevel gear, longitudinal axis, roller, rack slide, tooth bar, fixture, gear, lateral shaft, slide block, lock-screw, it is characterized in that: described base and guide rail are rigidly connected, supporting leg is connected with base hinge, slide block coordinates and realizes linear slide with guide rail, tooth bar and fixture are rigidly connected, rack slide is rigidly fixed on chassis, chassis is rigidly fixed on slide block, roller and longitudinally bevel gear are all rigidly connected with longitudinal axis, laterally bevel gear and gear are all rigidly connected with lateral shaft.
Wherein, the move basic circle at place of the plane that the reticule of tooth bar forms along rack tooth cross direction and roller is tangent.
Wherein, in the plane that the top of described fixture clamping drawing instrument forms along rack tooth cross direction in reticule.
Wherein, described tooth bar can be in rack slide linear slide, wheel and rack engagement.
Wherein, by the engagement of two bevel gears, realize the change of transmission direction.
Wherein, slide block is realized the axial restraint with guide rail by lock-screw.
The beneficial effects of the utility model: there is easy to use, the with low cost and advantage such as be easy to carry, theory of mechanics is as a mechanical basic subject, in involute gear study, can utilize the utility model accurately to draw the involute that different basic circles are corresponding, be convenient to the generative process that student understands involute.

the specific embodiment
According to Fig. 1, shown in Fig. 2, a kind of variable circle involute generator, comprise supporting leg 1, base 2, guide rail 3, chassis 4, longitudinal bevel gear 5, horizontal bevel gear 6, longitudinal axis 7, roller 8, rack slide 9, tooth bar 10, fixture 11, gear 12, lateral shaft 13, slide block 14, lock-screw 15, it is characterized in that: described base 2 is rigidly connected with guide rail 3, supporting leg 1 and base 2 chain connections, slide block 14 coordinates and realizes linear slide with guide rail 3, tooth bar 10 is rigidly connected with fixture 11, rack slide 9 is rigidly fixed on chassis 4, chassis 4 is rigidly fixed on slide block 14, roller 8 and longitudinally bevel gear 5 are all rigidly connected with longitudinal axis 7, laterally bevel gear 6 and gear 12 are all rigidly connected with lateral shaft 13.
Wherein, the move basic circle at place of the plane that the reticule of tooth bar 10 forms along tooth bar 10 facewidth directions and roller 8 is tangent.
Wherein, in the plane that the top of described fixture 11 clamping drawing instruments forms along tooth bar 10 facewidth directions in reticule.
Wherein, described tooth bar 10 can be in the interior linear slide of rack slide 9, gear 12 and tooth bar 10 engagements.
Wherein, by the engagement of two bevel gears, realize the change of transmission direction.
Wherein, slide block 14 is by the axial restraint of lock-screw 15 realizations and guide rail 3.
operation principle:
When using the utility model to draw involute, first adjusting slider is to required basic circle size, by the fixing slide position of lock-screw, and make supporting leg be close to blackboard surface, by rotary rail, make roller on blackboard surface, do pure rolling, by the engagement of two bevel gears, realize the change of transmission direction, laterally bevel gear driven gear rotates, and tooth bar slides in rack slide, and drawing fixture clamping drawing instrument is accurately depicted involute path.
Finally it should be noted that the only restriction for the technical solution of the utility model is described but not to the utility model protection domain of above embodiment.Although the utility model is explained in detail with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that and can modify or be equal to replacement the technical solution of the utility model, and do not depart from essence and the scope of technical solutions of the utility model.
