Definitions
- the invention is based on a hand-guided, Orbital sander in the preamble of claim 1 defined genus.
- the hand-held orbital sander according to the invention with the characteristic features of claim 1 has in contrast the advantage that the trained according to the invention Swing body for flexible connection of the tool holder symmetrical power distribution to the housing.
- the torque of the tool holder with vibrating body can about the hardness or thickness of the elastic molded part can be varied as required.
- the vibrating body met ideally the demands for a possible "hard” twisting on the one hand, which is advantageous for the Grinding abrasion is, and a "soft" shift over the eccentric pin on the other hand, which is advantageous for the Load on the pivot bearing.
- the vibrating body according to the invention enables a compact and flat design of the orbital sander and works additionally as a seal against the grinding dust on the bottom Bearing one end of the eccentric, from Electric motor driven work shaft.
- Fig. 1 in side view and hand-guided, partly cut, electric orbital sander in particular is known as Delta grinder executed, which is a triangular, symmetrical grinding plate as a grinding tool 10 carries.
- the bottom of the plastic sanding plate is not with a Velcro covering 11 for receiving provided sanding sheets.
- the Orbital sander can also with one be rectangular or equipped with other grinding tools, e.g. one Flap grinding attachment or a grinding tongue or one Slip pipe are operated.
- the orbital sander has a double-shell housing 12, which is composed of two housing shells 121, 122 those running along a parallel to the longitudinal axis of the housing Butt joint 123.
- a Electric motor 13 added, of which in Fig. 1 only the fan 15 seated on the output shaft 14 can be seen is.
- Switch slide 16 is used to switch the on and off Electric motor 13.
- the output shaft 14 drives via Angular gear 17 on a working shaft 18, which in two Ball bearings 19a and 19b fixed to the housing is rotatably mounted and on the lower end of the housing 12 with a Eccentric pin 20 protrudes from the housing 12.
- the vibrating body 23 which in FIGS. 2 and 3 in plan view and is shown in side view or in section, is as Ring formed with its radially inner Area on the tool holder 22 and with its radially outside lying area on the housing 12 can be fastened.
- the vibrating body 23 consists of a Inner ring 26, one concentrically arranged thereto Outer ring 27 and an annular molded part 28 elastic material, the inner and outer ring 26,27 connects with each other.
- Inner ring 26 and outer ring 27 are made of plastic and the molded part 28 is made of rubber or made of a sprayable soft plastic.
- the annular shaped part 28 an N-shaped cross section, the two axially extending concentric, annular legs 281,282 each firmly with the inner ring 26 and the outer ring 27 are connected.
- this can also have an M-shaped cross section, as in the vibrating body 23 is shown in FIG. 1.
- the Inner ring 26 is coaxial with the tool holder 22 Ball bearing 21 attached and the outer ring 27 is in the housing 12 held in rotation.
- the outer ring 27 is applied the outside of which is distributed over the circumference, integrally molded knobs 29.30, which fit in corresponding grooves formed in the housing 12 inlay.
- knobs provided here 29.30 are the two diametrically opposite Knobs 30 T-shaped so that you each Center web 301 strives radially away from the outer ring 27 and the Cross bar 302 is received in a groove 31, which is in half in a housing shell 121, 122 up to the parting line 123 is sufficiently trained.
- Fig. 1 are of the two Grooves 31 to see only the halves of the groove in the Housing shell 121 are formed.
- the inner ring 26 is on one on the top of the tool holder 22 coaxial to the axis 25 of the ball bearing 21 formed ring connector 32 pushed on and firmly connected to it, e.g. welded or glued.
