Detailed Description
The powder metallurgy driving clutch sleeve of the washing machine is of an integrated structure (see the attached figures 1, 2 and 3 in the specification). The powder metallurgy driving clutch sleeve of the washing machine is prepared by taking metal powder as a raw material and forming and sintering the metal powder, and the production formula and the process of the clutch sleeve are the prior art.
The powder metallurgy driving clutch sleeve of the washing machine is composed of a clutch sleeve body 1, a meshing gear ring 3, an inner boss 4 and an outer boss 5 (refer to the attached figures 1, 2 and 3 in the specification).
The clutch sleeve body 1 is of a cylindrical structure; the end face of one end of the clutch sleeve body 1 is provided with a plurality of transmission clamping grooves 6 (refer to the attached figures 1 and 4 in the specification) in a divergent shape.
The section of the transmission clamping groove 6 is of a U-shaped structure; the axial depth of the transmission clamping groove 6 is half of the thickness of the clutch sleeve body 1; the radial depth of the transmission clamping groove 6 is 0.15 times of the diameter of the clutch sleeve body 1 (see the attached figures 1 and 4 of the specification). When the powder metallurgy driving clutch sleeve of the washing machine works, power is transmitted outwards through the transmission clamping groove 6. With the purpose that transmission slot 6 so set up: firstly, a good stress state can be kept between the transmission clamping groove 6 and the clutch sleeve body 1, and the problem that the transmission clamping groove 6 is cracked with the clutch sleeve body 1 when stressed is avoided; and secondly, the size of the powder metallurgy driving clutch sleeve of the washing machine is reduced as much as possible, the material consumption is reduced, and the production cost is saved.
An outer boss 5 is arranged at the center of one end face of the clutch sleeve body 1; an inner boss 4 is arranged at the center of the other end face of the clutch sleeve body 1 (see the attached figure 2 of the specification).
The inner boss 4 and the outer boss 5 are both in a circular structure; the diameters of the inner boss 4 and the outer boss 5 are 0.65 time of the diameter of the clutch sleeve body 1; the thickness of the inner boss 4 and the outer boss 5 is one tenth of that of the clutch sleeve body 1. The purpose of thus providing the inner boss 4 and the outer boss 5 is: firstly, when the powder metallurgy driving clutch sleeve of the washing machine works, the transmission system of the washing machine carries out power transmission through the transmission hole 2 of the clutch sleeve body 1; therefore, after the inner boss 4 and the outer boss 5 are arranged, the transmission strength of the driving clutch of the washing machine can be enhanced through the inner boss 4 and the outer boss 5, and the risk of 'cracking' when the transmission system of the washing machine only applies main power to the clutch sleeve body 1 is reduced. Secondly, when the washing machine is driven to be assembled, the positions of the inner boss 4 and the outer boss 5 are main stress points of a powder metallurgy driving clutch sleeve of the washing machine; after the arrangement, the compression strength of the driving clutch of the washing machine can be enhanced, and the risk of fracturing is reduced.
The center of the end face of the inner boss 4 is provided with a meshing gear ring 3 (see the attached figures 3 and 5 in the specification); when the powder metallurgy driving clutch sleeve of the washing machine works, a transmission system of the washing machine can drive the clutch sleeve to synchronously rotate through the transmission hole 2 and the meshing gear ring 3; after the arrangement, the powder metallurgy driving clutch sleeve of the washing machine can enhance the torsional strength through the transmission hole 2 and the meshing gear ring 3; the risk of the drive clutch of the washing machine being twisted and cracked is reduced.
The thickness of the meshing gear ring 3 is three tenths of that of the clutch sleeve body 1; the circumferential surface of the meshing gear ring 3 is uniformly provided with meshing teeth 7; the end face of the meshing gear ring 3 on one side of the meshing teeth 7 is provided with a reinforcing ring rib 8. The purpose of setting up reinforcing ring muscle 8 lies in: because this washing machine's powder metallurgy drive separation and reunion cover passes through the in-process of meshing ring gear 3 transmission moment of torsion, the cracked problem that the stress concentration leads to most easily takes place for the end of meshing tooth 7, consequently sets up reinforcing ring muscle 8 at its end back, can strengthen the intensity of meshing tooth 7 to the pertinence, so can avoid meshing tooth 7 to take place the problem of "fracture" from the end.
The centers of the clutch sleeve body 1, the meshing gear ring 3, the inner boss 4 and the outer boss 5 are provided with a transmission hole 2 (see the attached figures 2, 4 and 5 in the specification).
The section of the transmission hole 2 is of a square structure; the corner part of the transmission hole 2 is in an arc-shaped structure; the width of the transmission hole 2 is one fourth of the diameter of the clutch sleeve body 1. The purpose of arranging the drive bore 2 in this way is: so that the driving system of the washing machine can drive the driving clutch action of the washing machine through the transmission shaft and the transmission hole 6 with the same structure with the transmission hole 6 when in work, thus avoiding the problem of 'cracking' of the driving clutch of the washing machine caused by stress concentration when in key transmission mode transmission.
The powder metallurgy driving clutch sleeve of the washing machine has compact structure and ingenious design, and is prepared by adopting metal powder as a raw material through forming and sintering; the use requirement of the transmission system of the washing machine can be met, the problems of heavy weight and high manufacturing cost of a steel clutch sleeve can be solved, and the transmission system of the washing machine is particularly suitable for the use requirement of the transmission system of the washing machine.
