Description
Technical field
The utility model belongs to the technical field of electric tool, is specifically related to a kind of portable makita 4100NH that is provided with the non-contact type dust and water proof apparatus.
Background technology
Portable makita 4100NH cutting operation is used two kinds of cutting blades, a kind of is dry plate, during its cutting, dust is large, a kind of is humidity strip, portable makita 4100NH as shown in Figure 3, need use water cooling during its cutting, dustproof rubber ring 20 and output shaft 21 close contacts of just leaning on are realized waterproof, dustproof, but while working due to machine, output shaft 21 High Rotation Speeds and rubber ring 20 have formed friction, rubber ring 20 can wear and tear very soon, thereby contact and closely do not cause into water or dust with output shaft 21, bearing 19 damages machine failure, while also having another shortcoming to be machine work, thereby rubber ring 20 rubs and produces the power of resistance loss machines with output shaft 21.Relevant portable makita 4100NH people have proposed as notification number: CN 2254398, the patent No.: 96203888.1 " makita 4100NHs ", publication number: CN 2254398, number of patent application: 200610051877.9 technical schemes such as " new no-dust stone cutting machines ", but all fail propose to solve the technical scheme of the disadvantage of above-mentioned existence.
Summary of the invention
The purpose of this utility model is will propose for a kind of portable makita 4100NH that is provided with the non-contact type dust and water proof apparatus, it adopts touchless dustproof, water-tight device, the rubber ring that has solved existing portable makita 4100NH existence can wear and tear very soon, thereby contact the disadvantage that does not closely cause causing into water or dust the bearing damage machine failure with output shaft, and can guarantee that its device is permanent not bad, the problem of the power attenuation of also having avoided rubber ring to cause.
Above-mentioned goal of the invention is achieved through the following technical solutions, a kind of portable makita 4100NH that is provided with the non-contact type dust and water proof apparatus, it comprises casing, motor in casing, the main shaft of motor, driving gear on main shaft, pass through fore bearing, rear bearing is contained in protecgulum, output shaft on head capsule, be contained in the driven gear meshed with driving gear on output shaft, the cutting blade of installing on output shaft, the hold-down bolt of cutting blade is installed on output shaft, lower platen, top board, be arranged on the casing head cover and the head capsule of cutting blade, it is characterized in that being provided with dust and water proof apparatus between fore bearing and lower platen, dust and water proof apparatus is on head capsule, to be equipped with the protecgulum of fixing and covering fore bearing is installed, be shaped with the groove of a circle on the front end face of protecgulum, between fore bearing and lower platen, waterproof dustproof ring is housed on output shaft, waterproof dustproof ring and output shaft are sealed and matched and synchronize rotation, and waterproof dustproof ring is shaped with the outer ring in the groove that puts in protecgulum, the outer ring of waterproof dustproof ring puts in interior the latter two formation labyrinth structures of groove of protecgulum.
The utility model is because after the outer ring of waterproof dustproof ring puts in the groove of protecgulum, the two forms labyrinth structure, so work as portable makita 4100NH in the stone material cutting process, waterproof dustproof ring has been arranged on cooling water and dust adhering, because waterproof dustproof ring and output shaft are sealed and matched and synchronize rotation, so the cooling water on waterproof dustproof ring and dust can't enter in fore bearing, can play good water proof and dust proof effect.And the cooling water on the waterproof dustproof ring rotated and dust by getting rid of in the groove of protecgulum the outer ring of waterproof dustproof ring, thereby make cooling water and dust can't enter fore bearing because the effect of centrifugal force is arranged, fore bearing is effectively protected; In addition, again because waterproof dustproof ring and output shaft are sealed and matched and synchronize rotations, thus one be not have the generation clearance issues of wearing and tearing between the two, the 2nd, thus there do not is the power problem of phase mutual friction generation resistance loss machine between the two yet.Therefore in the service life that the utility model can effectively improve portable makita 4100NH, reduce power consumption.
