Abstract
The utility model discloses a low noise friction formula grinder, including the motor output shaft, the transmission shaft of abrasive disc is equipped with to the tip, be equipped with a pair of friction drive wheel of mutually supporting between output shaft and the transmission shaft, the cross-section of friction drive wheel is the umbrella-type, and two inclined planes mutually support the transmission. The utility model discloses having changed original bevel gear into no tooth friction wheel, the material has changed into the rubber and plastic by the metal, and the shape is unchangeable basically, relies on the frictional force between two inclined planes to drive, consequently, not only greatly reduced the produced noise when grinder uses, also greatly reduced the manufacturing cost of grinder.
Description
The utility model relates to a kind of electric tool.
In the existing electric tool, the transmission of sander all is to be finished by a pair of bevel gear that is arranged between mutually perpendicular motor output shaft and the emery disc power transmission shaft, gap between the bevel gear can make a noise when work, adding also has noise to produce between sander itself and the working face, make that the noise of sander is just bigger.
The purpose of this utility model is: a kind of low noise friction-type sander is provided, and it makes existing umbrella shape travelling gear into anodontia friction drive wheel, comes transmission by rubbing surface, thereby greatly reduces the noise that is produced when sander is worked.
The technical solution of the utility model is: a kind of low noise friction-type sander, comprise motor output shaft, and the power transmission shaft of emery disc is equipped with in the end, is provided with a pair of friction drive wheel of working in coordination between described output shaft and the power transmission shaft.
The further technical scheme of the utility model is: a kind of low noise friction-type sander, comprise motor output shaft, and the power transmission shaft of emery disc is equipped with in the end, is provided with a pair of friction drive wheel of working in coordination between described output shaft and the power transmission shaft; The cross section of described friction drive wheel is umbrella shape, the transmission of working in coordination of two inclined-planes.
The utility model has the advantages that:
1. because the utility model has made original bevel gear into anodontia friction pulley, material has made rubber and plastic into by metal, and shape is constant substantially, rely on the frictional force between two inclined-planes to come transmission, therefore, not only greatly reduce the noise that is produced when sander uses, also greatly reduce the manufacturing cost of sander.
2. two friction pulleys are not to be pure rolling when transmission, also exist sliding motion between them, so the gearratio between motor output shaft and the emery disc power transmission shaft is lossy, but sander there is no higher requirement to this, so the utlity model has suitable practical value.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model.
Wherein: 1. motor output shaft; 2. emery disc; 3. emery disc power transmission shaft; 4. friction drive wheel.
Embodiment: as shown in Figure 1, a kind of low noise friction-type sander comprises motor output shaft [1], and the power transmission shaft [3] of emery disc [2] is equipped with in the end, is provided with a pair of friction drive wheel of working in coordination [4] between described output shaft [1] and the power transmission shaft [3]; The cross section of described friction drive wheel [4] is umbrella shape, the transmission of working in coordination of two inclined-planes.Because the utility model has made original bevel gear into anodontia friction pulley, material has made rubber and plastic into by metal, and shape is constant substantially, rely on the frictional force between two inclined-planes to come transmission, therefore, not only greatly reduce the noise that is produced when sander uses, also greatly reduce the manufacturing cost of sander; Two friction pulleys are not to be pure rolling when transmission, also exist sliding motion between them, so the gearratio between motor output shaft and the emery disc power transmission shaft is lossy, but sander there is no higher requirement to this, so the utlity model has suitable practical value.
Claims (2)
1. a low noise friction-type sander comprises motor output shaft [1], and the power transmission shaft [3] of emery disc [2] is equipped with in the end, it is characterized in that: be provided with a pair of friction drive wheel of working in coordination [4] between described output shaft [1] and the power transmission shaft [3].
2. low noise friction-type sander according to claim 1 is characterized in that: the cross section of described friction drive wheel [4] is umbrella shape, the transmission of working in coordination of two inclined-planes.
