Abstract
The utility model relates to a mechanical transmission mechanism, in particular to a pendulum shaft type gear transmission mechanism. According to the pendulum shaft type gear transmission mechanism, an included angle between an input shaft and an output shaft can be changed in the power transmission process. The pendulum shaft type gear transmission mechanism comprises a gear installed on a wheel axle. The wheel axle is installed on an axle base. The gear comprises a gear edge and gear teeth arranged on the gear edge. The gear teeth comprise cylinder parts arranged between the two end faces of the gear, and fan body parts arranged outside the end faces. The fan body parts are fan-shaped bodies formed by sweeping fan shapes of contour lines of the cylinder parts. The axle base is provided with a rotating shaft perpendicular to the wheel axle. The pendulum shaft type gear transmission mechanism is simple in structure and wide in application range and has high application value and economic benefits, and the included angle between the input shaft and the output shaft can be changed.
Description
Technical field
The utility model relates to a kind of mechanical transmission mechanism, the changeable pivoted axle gear drive of the angle of input shaft and output shaft while being a kind of transferring power specifically.
Background technique
Existing gear drive is usually used in the rotation motion between passing shaft, common cylindrical gears transferring power, and input shaft and output shaft must be arranged in parallel; Angular wheel can be realized the transmission of power of any angle between input shaft and output shaft.But above-mentioned two kinds of gear transmission structures, the angle between input shaft and output shaft must be changeless, cannot change the angle between input shaft and output shaft in the course of the work.In industrial robot arm joint and other Universal drive speed regulating mechanisms, often need to change at any time the gear drive of the angle of input shaft and output shaft.
Summary of the invention
The purpose of this utility model is to provide the changeable pivoted axle gear drive of angle of a kind of simple in structure, input shaft and output shaft.
The utility model is that the technological scheme that technical solution problem adopts is:
Pivoted axle gear drive described in the utility model, comprise the gear being arranged on wheel shaft, described wheel shaft is arranged on axle bed, described gear comprises wheel rim, is arranged on the gear teeth on wheel rim, it is characterized in that: the described gear teeth comprise trunk portion between gear both ends of the surface, are positioned at the fan body portion in end face outside, described fan body portion is the quadrant that the fan-shaped sweeping of profile line by trunk portion forms; Described axle bed is provided with the rotating shaft perpendicular to wheel shaft.
Described axle bed comprises by two hinged pedestals of rotating shaft, and on two pedestals, by wheel shaft, one gear is respectively installed, two gears are intermeshing, and the axis of described rotating shaft is by the trunk portion of engaging tooth and the separatrix of fan body portion.
Owing to having adopted said structure, the utility model is simple in structure, the angle of input shaft and output shaft can change, have wide range of applications, except contributing to improve robot arm working efficiency and optimize the advantages such as original driving mechanism, also can be applicable to the variable gearbox of outbound course and improve and simplify the driving mechanism of a lot of engineering goods, improve transmission efficiency, reduce product cost, also can be used as independent Universal drive speed regulating mechanism and speed changer and support the use, there is very high using value and economic benefit.

Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, pivoted axle gear drive described in the utility model comprises the gear 3,4 being arranged on wheel shaft 1,2, and described wheel shaft 1,2 is arranged on axle bed 5,6, and described axle bed 5,6 is provided with the rotating shaft 7 perpendicular to wheel shaft 1,2.Described axle bed 5,6 comprises by two hinged pedestals of rotating shaft 7, and on two pedestals, by wheel shaft 1,2, a gear is respectively installed, two gears are intermeshing.
As shown in Figure 4, Figure 5, described gear 3,4 comprises wheel rim 31, is arranged on the gear teeth on wheel rim 31, the described gear teeth comprise trunk portion 32 between gear both ends of the surface, are positioned at the fan body portion 33 in end face outside, and described trunk portion 32 can adopt existing various column tooth-formation of gear.As shown in Figure 6, described fan body portion 33 is quadrants that the fan-shaped sweeping of profile line by trunk portion 32 forms, and the angle of quadrant can be not more than 90 degree arbitrarily angled; Described axle bed 5,6 is provided with the rotating shaft 7 perpendicular to wheel shaft 1,2.
During use, pedestal can 7 swing around the shaft between two, thereby drive two axles 1,2, change its angle, the trunk portion 32 of the axis of rotating shaft 7 by engaging tooth and the separatrix of fan body portion 33, in two axles 1,2 during in parastate, trunk portion 32 engaging stress of the gear teeth, when two axles 1,2 is during in plumbness, fan body portion 33 engaging stress of the gear teeth.Like this, as long as the angle between two axles 1,2 is within 90 degree, this pivoted axle gear drive is effective carry-over moment all.
