- Coupling surface and the second coupling surface is disposed a friction lining.
- the first coupling element consists of a sleeve-shaped first fastening part and a thereto
- the second coupling element consists of a sleeve-shaped second fastening part and a subsequent thereto sleeve-shaped second coupling disk part and the outer surface is arranged to increase the heat dissipation in the region of the peripheral surface of the first coupling disk part. It is particularly advantageous that in a blocked transmission and thus a response of the
- the first clutch disk part is further rotated by the drive motor and thus further from the thread-like depressions transmission oil is conveyed into the bore and thus further cooling takes place.
- the second fastening part is advantageously in the first
- Coupling element inserted is that the slip clutch in a bore of a
- Housing of the transmission is arranged.
- Gear is arranged, which communicates with the bore and is filled with a transmission oil.
- a gap is arranged between the cylindrical outer surface of the slip clutch and the inner surface of the bore.
- Figure 1 is a sectional view of a chain hoist according to the invention.
- FIG. 2 shows an enlarged detail of FIG. 1 from the region of FIG.
- FIG. 1 shows a sectional view of a chain hoist 1 according to the invention.
- the chain hoist 1 is powered by an electric drive motor. 2
- the drive motor 2 has a motor shaft 2 a, which is connected with its output side end via the slip clutch 4 to the transmission 5.
- the slip clutch 4 consists essentially of a first coupling element 4a and a second coupling element 4b, which are mutually engaged via a friction lining 4c (see FIG. 2).
- the first coupling element 4a is arranged concentrically with respect to the motor shaft 2a and on the output side end in a rotationally fixed manner.
- the second coupling element 4b is concentric with a transmission input shaft 5a and rotationally fixed on its first end arranged.
- the motor shaft 2a and the transmission input shaft 5a seen in the longitudinal direction are arranged one behind the other and concentric with each other.
- the opposite second end is the
- Transmission input shaft 5a mounted in an outer wall 3a of the housing 3. At this second end engages an electrically releasable brake 7, which is supported on the outside of the outer wall 3a.
- the brake 7 is disposed under a cover 8 which is fixed to the outside of the outer wall 3a.
- the cover 8 provides sufficient space to accommodate electrical and / or electronic components protected.
- the transmission input shaft 5a slidably mounted in the axial direction and on the other hand is supported via a spring element 9 on the inside of the outer wall 3a. Furthermore, the transmission input shaft 5a is formed as a pinion shaft with a first gear 10a, which meshes with a second gear 10b of the transmission 3. The two gears 10a, 10b thus form the first gear stage.
- the first gear 10a of the transmission input shaft 5a is formed with a helical toothing in such a way that during operation of the
- Triggering moments are brought about. This is associated with the advantage that in a reversal of the power flow direction in the transmission 5 by a hooking of the chain on the non-load side then the axial force of the teeth of the bias of
- Torque is lowered. The risk of damage to the chain hoist 1 is thereby reduced.
- the transmission 5 has a transmission output shaft 5b which runs parallel to the transmission input shaft 5a and is mounted laterally offset in the housing 3.
- the output side is rotatably on the transmission output shaft 5b and arranged concentrically to this the sprocket 6, with a chain 1 1 of the chain hoist 1 can be moved in the lifting and lowering.
- Transmission input shaft 5a and the transmission output shaft 5b are in one
- Gear chamber 5 c arranged, which is bounded by the housing 3.
- the gear chamber 5c is filled in the usual way with a transmission oil.
- the chain hoist 1 can be hung at a desired location by means of an eyelet, not shown, which engages the outside and top of the housing 3.
- FIG. 2 shows an enlarged detail of FIG. 1 from the area of FIG.
- Slip clutch 4 of the chain hoist 1 It can be seen that the slip clutch 4 is arranged in a bore 12 in an intermediate wall 3b of the housing 3.
- the bore 12 has a circular cross-section with an inner surface 12a and an inner diameter i, which is slightly larger than the outer diameter d of the slip clutch 4.
- the slip clutch 4 is substantially cylindrical with a stepped outer surface 4d. Between the inner surface 12a of the bore 12 and the outer surface 4d of the slip clutch 4, a gap s running around the slip clutch 4 remains, which is approximately in the range of 1 mm to 5 mm.
- the bore 12 extends with its bore wall 12b, starting from the intermediate wall 3b in the direction of the drive motor 2 and the bore wall 12b forms a kind of approach to the intermediate wall 3b.
- the slip clutch 4 consists essentially of the first coupling element 4a and the second coupling element 4b.
- the mounted on the motor shaft 2a first coupling element 4a has substantially the shape of a sleeve with a
- Flange approach which can be divided into a first fastening part 4e and a flange-like first coupling disk part 4f.
- the fastening part 4e and the coupling disk part 4f differ essentially in their different outer diameters a, b.
- Fastening part 4e goes abruptly in the outer diameter b of
- annular contact surface 4g is provided on the coupling disk part 4f, on which the inner ring 13a of a
- Ball bearing 13 is applied, via which the fastening part 4e and thus the motor shaft 2a inserted therein is mounted on the inner surface 12a of the bore 12. Adjacent to the ball bearing 13 in the direction of the drive motor 2 is a Sealing ring 14 mounted on the mounting part 4 e, the outside of the
- these recesses 15 are formed as circumferential threads, the movement of the threads is chosen so that in the Hubbetreib the chain hoist 1 of the threads
- the first coupling disk part 4 f can be arranged completely in the bore 12.
- the requirements for sufficient cooling of the second coupling element 4b are easier to fulfill, since the second coupling element 4b is arranged on a gear chamber 5c facing the end of the bore 12 and thus can easily deliver the frictional heat to the transmission oil.
- the second coupling element 4b basically has the same construction as the first coupling element 4a, wherein the recesses 15 and the oversizing are not required.
- the second coupling element 12b has the form of a sleeve with a flange attachment, which can be divided into a second fastening part 4i and a flange-like second coupling disk part 4j.
- the second attachment part 4i and the second Clutch disk part 4j differ essentially by their different outer diameters e, f.
- Fastening part 4i goes abruptly in the outer diameter f of
- Clutch disc part 4j an annular second coupling surface 41 created on which the annular friction lining 4c is glued.
- the friction lining 4c abuts with its opposing friction surface on the first coupling surface 4k of the second coupling disk part 4j.
- the first annular coupling surface 4k is arranged parallel to the contact surface 4g of the first coupling disk part 4f and lies on the side of the first coupling disk part 4f opposite the contact surface 4g.
- the second clutch disk part 4j has one to the second
- Coupling surface 41 parallel and opposed thereto annular surface 4m, which is arranged at the end of the bore 12 and the gear housing 5c facing. Accordingly, the second coupling element 4b to cool well over the annular surface 4m.
- Clutch disk part 4f is inserted and is mounted on a needle bearing 17. Accordingly, the outer diameter e of the second fastening part 4i is smaller than the inner diameter of the coupling bore 16. As a result, the friction lining 4c can then come to bear against the first coupling surface 4k of the first coupling element 4a.
