Abstract
The utility model provides a damping gear for an electric tool, which is low in abrasion, high in lubricating performance and long in service life. The damping gear comprises a gear body, teeth and a tooth socket, wherein the teeth and the tooth socket are positioned on the gear body; an annular hole passing through the teeth and the tooth socket is formed on the gear body; an annular damping element is arranged in the annular hole; a plurality of through holes are distributed on the annular damping element; lubricating oil is filled into the annular hole; and a baffle plate is fixed at the lower end of the annular hole. In the damping gear for the electric tool disclosed by the utility model, the damping element is arranged at the middle position of the root of the teeth, so that advanced abrasion is avoided; and the damping element is provided with the plurality of through holes, and lubricating oil is sealed in the annular hole, so that the teeth can be lubricated through the damping element, the abrasion of the teeth is reduced, and the service life of the damping gear is prolonged.
Description
Technical field
The utility model relates to a kind of gear, and especially a kind of electric tool is used the damping gear.
Background technique
In the gear drive of electronic hand-held machine tool,, use the gear of making through sintering usually from the reason of manufacture cost.Especially the gear drive of being made up of the gear of sintering has high tolerance, the particularly error of graduation that is caused by manufacturing; Profile of tooth deviation and radial missing, this will produce inevitable backlash, and this backlash will cause moving significantly noise again and produce vibration; Therefore a kind of noise damping gear little with vibration appearred; But the damping member of existing damping gear is arranged on the gear edge, causes the wearing and tearing in advance of gear drive, reduces the working life of damping gear.
The model utility content
The purpose of the utility model be to provide a kind of wear and tear little, lubricate, the electric tool of long service life uses the damping gear.
The technological scheme that realizes the utility model purpose is following:
Electric tool is used the damping gear, comprises the gear body, is positioned at teeth and teeth groove on the said gear body; Be positioned at said gear body and be provided with the looping pit that runs through said teeth and teeth groove; Be provided with annular damping member in the said looping pit; Be distributed with a plurality of through holes on the said annular damping member, be provided with lubricant oil in the said looping pit, the lower end of said looping pit is fixed with baffle plate.
Said baffle plate and said gear body interference fit.
The beneficial effect of the utility model is following:
The electric tool of the utility model is used the damping gear; Because damping member is provided with the root neutral position of teeth, has therefore avoided wearing and tearing in advance, and on damping member, had a plurality of through holes; Envelope has lubricant oil in the looping pit; Can be lubricated to teeth through damping member, reduced the friction of teeth, therefore improved working life.
Description of drawings
Fig. 1 is the structural representation of the utility model electric tool with the damping gear.
Embodiment
The embodiment of the utility model is following:
As shown in Figure 1, the electric tool of the utility model is used the damping gear, comprises gear body 1, is positioned at teeth 2 and teeth groove 3 on the said gear body 1; Be positioned at said gear body 1 and be provided with the looping pit 4 that runs through said teeth 2 and teeth groove 3; Be provided with annular damping member 5 in the said looping pit 4; Be distributed with a plurality of through holes 51 on the said annular damping member 5, be provided with lubricant oil in the said looping pit 4, the lower end of said looping pit 4 is fixed with baffle plate 6.Said baffle plate 6 and said gear body 1 interference fit.
The electric tool of the utility model is used the damping gear; Because annular damping member 5 is provided with the root neutral position of teeth 2, has therefore avoided wearing and tearing in advance, and on annular damping member 5, had a plurality of through holes 51; Envelope has lubricant oil in the looping pit 4; Can give teeth 2 lubricated through damping member 5, reduce the friction of teeth 2, therefore improve working life.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in related domain make the utility model technological scheme all should fall in the protection domain that claims of the utility model confirm.
Claims (2)
