Definitions
- Household laundry treating machine having a laundry drum drivable by an electric motor and method of assembling
- the invention relates to a household laundry treatment machine with a drivable by an electric motor laundry drum and a belt transmission between the laundry drum and electric motor, wherein the laundry drum is fixedly connected to a drive shaft and the drive shaft is connected to a pulley of the belt drive.
- the invention also relates to a method for
- Drive shaft is solid material that requires considerably more energy to melt in the welding process than the existing pulley, it must be feared that the softer sheet material is already melted away before the solid material of the drive shaft is melted binding and can get a material connection with the sheet material. Furthermore, the
- Belt pulley is fastened by means of several screws or only for fixing a flange to a wheel disc, corresponding to the pulley of the machine described above.
- This flange is fixed by a central screw with a shaft and held against rotation by a groove / wedge connection.
- the present invention has for its object to find a suitable for the aspects described above construction of a cohesive - non-destructive unsolvable - connection between the drive shaft and the pulley. This object is achieved by a household laundry treatment machine of the type described above, which features the characteristics of the
- Claim 1 and by an assembly method for such a machine according to the features in the characterizing part of claim 5 or 7.
- the pulley is provided in the region of the connection to the drive shaft with a flange with internal thread. Furthermore, the direction away from the laundry drum end of the drive shaft, which is preferably provided with a shallow cup-like depression, an engaging in the internal thread external thread. And the two threads are unsolvable, namely cohesively, interconnected and serve only the positionally secure preparation of the compound and the inclusion of a portion of the rotational forces occurring.
- Pulley can absorb heat at the same speed and Mende. Therefore, both components will melt at the same time and flow into each other. This is the basis for a reliable connection.
- the threaded connection automatically ensures the right-angled position of the pulley to the axis of the drive shaft. Due to the flange shape of both components to be joined together, the heat is introduced at a remote location from the rolling bearing and the rolling bearing protected. In addition, small melt zones are sufficient for the cohesive connection because the threaded connection already takes over part of the torques. The construction allows to adjust the
- weg inden end is mounted on a roller bearing and between the outer ring of the bearing and the washing drum facing the contact surface of the
- Pulley is arranged a spring ring, an additional axial force can be generated, which applies a part of the transmission torques and of the
- FIG. 1 shows in Fig. 1, the axial cross section of a bearing portion of a drive shaft for a flying support of a laundry drum in a front loader washing machine and in Fig. 2 is an exploded view of the connecting portion of the outer
- the rear wall 1 of a laundry drum 2 mounted in a - here a plastic tub - mounted laundry tub 2 is fixedly connected in Fig. 1 with a drive shaft 3. From the tub, only the part is shown here, in which the bearing housing 4 is integrated on its rear wall. Here, the bearing housing 4 is pierced for the drive shaft 3, which is mounted together with the laundry drum 2 in this bearing housing 4 on two rolling bearings 5 and 6 on the fly. In this case, the inner roller bearing 5 is protected by a shaft seal 7 - here only schematically indicated - against liquid from the tub.
- the drive shaft 3 has at the bearings heels that the seat of
- Pulley 12 engages.
- the pulley 12 is connected in a manner not shown here via a drive belt with a pinion of an electric motor.
- the end 8 is frontally provided with a pot-like recess 13 through which a
- the two annular end faces 15 and 16 of the flange 1 1 and the edge portion 14 are at least approximately in a plane and thus can easily from a weld 17 together be recorded, of which about three pieces or more evenly distributed on the end faces 15 and 16.
- the two end faces 15 and 16 may also be welded together in a closed annular manner.
- External thread 9 provided drive shaft 3 is inserted into the bearing housing 4 and the shaft seal 7 and the bearings 5 and 6 are pressed. According to FIG. 2, the internal thread 10 of the flange 11 of the pulley 12 is then screwed onto the external thread 9 with a hard stop. To apply higher axial forces a spring ring 18 is inserted between the inner ring of the outer roller bearing 6 and the bearing facing surface of the pulley 12, which is completely pressed when screwing the flange 1 1. Subsequently, the free ones
- Gluing technique can be varied instead of welding. This is done after the
- the external thread 9 is covered with a thin adhesive layer, and then only the internal thread 10 of the flange 1 1 screwed.
- the adhesive must be adjusted so that it fits with the
- a spring ring 18 can be inserted here, but welding after unscrewing is unnecessary. Rather, the glue has to be given time to cure, but until the next step in the assembly of the laundry treatment machine, the
- the invention is also intended to the kinematic reversal of
- the pot-like recess 13 should be slightly deeper than in the example shown.
- the thread would have to be attached to the flange 1 1 on the outside thereof to correspond to the thread of the end 8.
- the example shown is favored with regard to the distribution of the threads on the inside and outside.
