Abstract
The utility model discloses a driving gear for robot joints. The driving gear comprises a gearwheel and a pinion. The tooth profile of the pinion adopts cylindrical rollers in the interval and annular arrangement; the gearwheel adopts a cam wheel, with the cycloidal curve of a roller wheel as the tooth profile; and the teeth of the gearwheel are engaged with those of the pinion in the hollow parts of the spaced cylindrical rollers of the pinion. The utility model has the advantages that the gearwheel is in non-clearance fit with the pinion, the precision is high, and the noise is low, so that the utility model is particularly suitable for the joint driving gear of a spraying robot.
Description
Technical field
The utility model relates to a kind of driving gear, refers specifically to a kind of joint of robot driving gear.
Background technique
As shown in Figure 1, the driving gear on the existing market all adopts gear 1 and gear 2 to be meshing with each other, and the shortcoming that above-mentioned gear drive exists has: gear 1 and gear 2 are gapped, low precision, and also noise is big.
The model utility content
The purpose of this utility model is to provide a kind of joint of robot driving gear, and its two gear is in conjunction with no gap, the precision height, and noise is little.
In order to achieve the above object, the utility model is realized by following technological scheme.
A kind of joint of robot driving gear, this driving gear comprises a gearwheel and a small gear, it is characterized in that: the profile of tooth of small gear is the cylindrical rollers of interval annular arrangement, gearwheel is a cam, profile of tooth is a rod wheel cycloidal curve profile of tooth, and the tooth of gearwheel is in small gear cylindrical rollers hollow portion engagement at interval.
Described small gear cylindrical rollers both sides are provided with bearings.
The utility model beneficial effect is, adopts joint of robot driving gear of the present utility model, and its two gear is in conjunction with no gap, the precision height, and noise is little, is specially adapted to spraying robot person joint driving gear.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe in further detail.
A kind of joint of robot driving gear as shown in Figure 2, this driving gear comprises a gearwheel 3 and a small gear 4, the profile of tooth of the utility model small gear 4 is the cylindrical rollers 41 of interval annular arrangement, cylindrical rollers 41 is the highi degree of accuracy cylindrical rollers, and described small gear cylindrical rollers 41 both sides are provided with bearings.Gearwheel 3 is accurately machined cam, and profile of tooth is a rod wheel cycloidal curve profile of tooth, and the tooth of gearwheel 3 is in small gear 4 cylindrical rollers 41 hollow portions engagement at interval, and two gears always have two or three teeth to be meshing with each other, so just at two-way elimination gap, transmission accuracy height.Small gear cylindrical rollers 41 both sides are provided with bearings, rotate in that gearwheel rod wheel cycloidal curve profile of tooth is slick and sly during rotation, produce the small tooth sound that bumps, vibrate and noise minimum.
Please take turns the formation schematic diagram of cycloidal curve in conjunction with gearwheel 3 rods shown in Figure 3, rod 41 central point A contact gearwheel 3 on one side on the small gear 4 of contact gearwheel 3, track when the limit rotates becomes a basic cycloidal curve, with the A1 point is that the rod 41 periphery curves that draw in the center become basic profile of tooth, a plurality of rods that the center is arranged on small gear 4 circumference, because the rotation of small gear 4 forms annular gear wheel on gearwheel 3.
Claims (2)
1, a kind of joint of robot driving gear, this driving gear comprises a gearwheel and a small gear, it is characterized in that: the profile of tooth of small gear is the cylindrical rollers of interval annular arrangement, gearwheel is a cam, profile of tooth is a rod wheel cycloidal curve profile of tooth, and the tooth of gearwheel is in small gear cylindrical rollers hollow portion engagement at interval.
2, joint of robot driving gear according to claim 1 is characterized in that: described small gear cylindrical rollers both sides are provided with bearings.
