Technical field
The utility model relates to a kind of electric tool, relates in particular to a kind of oil-leakage-prevention electric hammer that effectively prevents armature spindle gear failure.
Background technology
Electric hammer is a kind of electrodynamic type rotation hammer drill electricity consumption class instrument of a kind of overload-release clutch with Pneumatic hammering mechanism.
Electric hammer is the class in electric drill, is mainly used to hole on concrete, floor, wall brick and stone material.
Electric hammer is on the basis of common electric drill, increases by one and is driven the piston that has crankshaft-link rod by motor, and reciprocating air in a cylinder, makes cylinder inner air pressure drive the hammer in cylinder back and forth to hit drill bit top.
Because also having produced along the fast reciprocating of the direction of electric drill bar in rotating, the drill bit of electric hammer moves (frequent impact), so it can punching fast on the larger material such as cement concrete and stone material of fragility.
But, current electric hammer on the market, easily there is oil leakage phenomenon in its gear-box and driver part, and meanwhile, its internal gear is easily damaged.
Utility model content
The purpose of this utility model is to provide a kind of convenient oil-leakage-prevention electric hammer of holding.
To achieve these goals, the oil-leakage-prevention electric hammer that the utility model provides comprises: instrument maintaining part, drive division and the rotation by drive division are transmitted into rotation to instrument maintaining part and the transmission mechanism of impact;
Transmission mechanism comprises gear-box, and gear-box is connected by middle cover with drive division, between middle cover and gear-box, is provided with leak-proof gasket.
Thus, leak-proof gasket effectively prevents that oil leakage phenomenon from appearring in gear-box.
In some embodiments, be provided with a main shaft in fuselage, one end of main shaft is connected with instrument maintaining part, is also provided with a jackshaft in fuselage, and jackshaft and main shaft be arranged in parallel, and jackshaft is connected with the drive motors in drive division, is driven and is rotated by drive motors.
Thus, jackshaft, by the gear drive in gear-box, is driven initiatively by the drive motors in drive division, jackshaft drive shaft running again, thereby the running of band power driven tools maintaining part.
In some embodiments, jackshaft is provided with rotation transmission part and impact transference part part, rotation transmission part, impact transference part part and jackshaft can be distinguished independent running, Clutch Control rotation transmission part and the running of jackshaft one, and control impact transference part part and the running of jackshaft one.
Thus, realize rotation and the straight reciprocating motion of workpiece by rotation transmission part, impact transference part part.
In some embodiments, rotation transmission part is two travelling gears of being located at jackshaft, and main shaft is provided with a transmitting gear of mediating mutually with two travelling gears, and main shaft is driven and rotated by drive motors under the transmission of travelling gear and transmitting gear.
Thus, realize the rotation of workpiece by the transmission of travelling gear and transmitting gear, meanwhile, jackshaft is mediated by the gear on two gears and main shaft, effectively prevents gear failure.
In some embodiments, impact transference part part is the Oscillating lever bearing that is provided with jackshaft, it is fixing that Oscillating lever bearing and jackshaft can not circumferentially rotate, also being provided with in addition a cylinder is connected with Oscillating lever bearing, cylinder head is provided with a hammer, and hammer is converted to the continuous rotation motion of jackshaft for the reciprocating linear of the workpiece in instrument maintaining part and impacts.
Thus, by Oscillating lever bearing, the axial rotation of jackshaft is converted to the reciprocating motion of cylinder, the reciprocating linear of realizing workpiece impacts.
Oil-leakage-prevention electric hammer of the present utility model compared with prior art, has the following advantages:
1. oil-leakage-prevention electric hammer of the present utility model, efficiently solves the Leakage of bearing housing.
2. oil-leakage-prevention electric hammer of the present utility model, is provided with two travelling gears of mediating with main shaft transmitting gear, reduces the wearing and tearing of travelling gear.
