Abstract

The utility model provides a novel clutch of steering wheel, in the drive gear of steering wheel, gear and pivot are not fixed connection, but the separation at the pivot excircle, is fixed with elasticity cusp boss, the interior circle of gear fluted with the pivot on elasticity cusp boss mate the meshing, when the steering wheel load is greater than the setting value, the shrink of elasticity cusp boss pressurized centering breaks away from the recess of circle in the gear, forms clutch formula and drive gear and throws off. The utility model provides an advantage be to receive the protection of carrying out the gear under the condition of heavy load to the gear of steering wheel to has solved when the steering wheel gear receives the heavy load in the existing market gear and has held perishable problem, greatly increased the reliability of steering wheel.

Description

The novel clutch of a kind of steering wheel

Technical field

The utility model relates to the clutch coupling of a kind of steering wheel.

Background technology

Steering wheel is as the driving mechanism of a kind of position servo, primarily of parts compositions such as shell, circuit card, motor, gears, owing to its volume is little, moment is big, integrated level height, it is widely used in telecontrolled model field (model airplane at present, model ship, remote control vehicle model etc.) and without man-machine, the fields such as service robot. Current steering wheel is substantially all that the wheel casing that low module (m < 1) straight tooth gear adopted is formed carries out output of slowing down, close-toothed gear capacity is a very big challenge concerning steering wheel, particularly steering wheel stall, or often occur when being subject to outside bigger load gear bad fall situation. This has certain restriction for wearing quality and the use occasion of steering wheel.

Summary of the invention

For solving steering wheel geartransmission process Problems existing, the utility model provides the Novel clutch of a kind of steering wheel

Device, in the transmitting gear of steering wheel, gear is not fixedly connected with rotating shaft, but separation, at rotating shaft cylindrical, it is fixed with Elastic Teeth shape boss, the inner circle of gear has groove to engage with the coupling of Elastic Teeth shape boss in rotating shaft, and when steering wheel load is greater than set(ting)value, Elastic Teeth shape boss is pressed to central reduction, depart from the groove of fillet of gear, form clutch type and transmitting gear disengagement.

Described Elastic Teeth shape boss is that C font ring cylindrical has tooth shape boss, and C font ring is thin-walled structure.

Described C font ring wall thickness, determine according to the load size of steering wheel.

Described C font ring, the quantity in rotating shaft is greater than 2.

The boss quantity of each C font ring cylindrical described, at least one.

The new advantage of this practicality is, it is possible to the gear of steering wheel carries out the protection of gear when being subject to heavy load, thus the problem that when solving that in existing market, steering wheel gear is subject to heavy load, gear is easily bad, considerably increase the reliability of steering wheel.

Fig. 1 is stereographic map of the present utility model;

Fig. 2 is the rotating shaft of Fig. 1 and the schematic diagram of gears meshing;

Fig. 3 be the rotating shaft of Fig. 1 and gears meshing well after the schematic diagram of plane;

Fig. 4 is the transmission schematic diagram of Fig. 2 in steering wheel wheel casing;

Number in the figure illustrates:

1-rotating shaft; 2-C font ring; 3-boss; 4-axle sleeve; 5-fillet of gear groove; 6-output gear; 7-wheel casing; 8-steering wheel shell; 9-motor; 10-circuit card; A, b, c, d, e, f-transmitting gear.

Embodiment

Refer to shown in accompanying drawing 4, output gear 6 transmitting gear f(is steering wheel here) rotating shaft 1 on fix two C font rings 2, C font ring 2 has three boss 3, inner circle at output gear 6 is provided with groove 5, engage with Elastic Teeth shape boss 3 coupling, then output gear 6 drives rotating shaft 1 to rotate, when steering wheel load is greater than set(ting)value, C font ring 2, to central reduction, makes tooth shape boss 3 exit and the interior round recessed 5 of its meshing gearwheel f. This prevents because load is too big, cause moment of torsion big, gear is damaged. Working as load reduction, moment of torsion reduces, and the boss 3 of C font ring 2 pops up, and automatically engages with the groove 5 of output gear 6 inner circle again, implements normal operation.

Referring to shown in accompanying drawing 1, at rotating shaft 1 cylindrical of gear, being fixed with two C font ring 2, C font ring 2 cylindricals has three boss 3.

Referring to shown in accompanying drawing 2, by the rotating shaft 1 of Fig. 1 with C font ring 2, coordinate with the interior round recessed 5 of output gear 6, boss 3 imbeds groove 5 and engages, and forms the engagement of clutch type output gear.
