Abstract
The utility model discloses a noise reduction gear box of an electric tool.A regulating gasket is sleeved on an output shaft in a gear box shell, and the regulating gasket is positioned between a shaft locking ring and a shaft locking block sleeved on the output shaft; the lower surface of the adjusting gasket is completely contacted with the shaft locking ring, one part of the upper surface of the adjusting gasket is completely contacted with the shaft locking block, and the other part of the upper surface of the adjusting gasket is simultaneously contacted with the shaft locking block and a shaft locking frame sleeved on the output shaft. The utility model discloses an increase adjusting shim between the axle locking piece that produces the abnormal sound in the gear assembly and axle lock circle, can conveniently adjust the emergence of the gear abnormal sound that leads to the high deviation to arouse because of the part difference. Through the utility model discloses such improvement design can effectively reduce the tooth sound of electric tool complete machine gear when the transmission under the condition that increases very few cost to improve electric tool's life.
Description
Technical Field
The utility model belongs to electric tool product field, concretely relates to electric tool noise reduction gear box is applied to the single double-speed electric drill among the electric tool product.
Background
At present, among electric tool products, electric drill products are widely applied and are often used on materials such as wood, metal, plastic and the like for punching and screwing. Under the condition that the electric drill product is normally started, the gear assembly in the machine reduces the rotating speed of the motor to the designed rotating speed to drive the drill chuck to rotate. However, due to the processing deviation and accumulated error of each part, abnormal deflection of gear components inside the machine can be caused, so that abnormal sound is generated by the machine, noise pollution is caused, and the service life of the product is influenced.
The prior art generally adopts the methods of improving the control precision of parts, adopting a machining method to control the size and the like, and although the methods can accurately control the clearance of the gear assembly inside a machine and effectively improve the abnormal sound generated during the transmission of the gear assembly, the methods have complex process and relatively high machining and assembling difficulty, so that the production cost of products is increased.
SUMMERY OF THE UTILITY MODEL
To the defect that exists among the above-mentioned prior art and not enough, the utility model aims at providing a gear box of making an uproar falls in electric tool to clearance in the minimum cost adjusting gear subassembly, thereby tooth sound when improving the gear assembly transmission, extension electric tool's life.
For realizing above-mentioned technical purpose, reach above-mentioned technological effect, the utility model discloses a following technical scheme realizes:
a noise reduction gearbox of an electric tool is characterized in that an output shaft in a gearbox shell is sleeved with an adjusting gasket, and the adjusting gasket is positioned between a shaft locking ring and a shaft locking block which are sleeved on the output shaft; the lower surface of the adjusting gasket is completely contacted with the shaft locking ring, one part of the upper surface of the adjusting gasket is completely contacted with the shaft locking block, and the other part of the upper surface of the adjusting gasket is simultaneously contacted with the shaft locking block and a shaft locking frame sleeved on the output shaft.
Further, according to the practical condition of the gear box, the thickness of the adjusting gasket is 0.1-0.5 mm.
Further, the adjusting gasket is a metal gasket subjected to heat treatment.
Further, the heat-treated hardness of the conditioning gasket is not less than HV 300.
The utility model has the advantages that:
the utility model discloses an increase adjusting shim between the axle locking piece that produces the abnormal sound in the gear assembly and axle lock circle, can conveniently adjust the emergence of the gear abnormal sound that leads to the high deviation to arouse because of the part difference. Through the utility model discloses such improvement design can effectively reduce the tooth sound of electric tool complete machine gear when the transmission under the condition that increases very few cost to improve electric tool's life. Through actual contrast, the utility model discloses an electric tool noise reduction gear box is showing the improvement effect of the different sound problem of gear, convenient assembling moreover, and the cost is lower.
The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.
