Definitions

  • the present invention relates to a laundry washing and drying machine, the production costs of which are reduced.
  • the movement of the motor is transferred to the drum by means of a shaft disposed on the support arms. Since the bush disposed on the shaft is worn away in the course of time due to frictions caused by the movement of the shaft, the bush should be produced from a durable material.
  • the bush is produced from brass which is a durable and malleable material.
  • the cost of the brass is high and should be mixed with lead so that the former can be processed. Since the lead adversely affects the human health and the environment, the use thereof has been subjected to new restrictions.
  • Aluminum iron alloys that are desired to be used instead of the brass do not meet the required surface hardness and strength values.
  • the aim of the present invention is the realization of a laundry washing machine or laundry washing drying machine, the production costs of which are reduced.
  • the washing machine realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof comprises a cylindrical body, a tub wherein the body is disposed, a drum spider that has more than one support arm enabling the movement of transmission elements such as electric motor, belt-pulley to be transferred to the body, a shaft that extends from the drum spider to the transmission elements and that transfers the movement of the transmission elements to the body, more than one bearing that allows the shaft to rotate and that centers the shaft, a bush that is disposed on the shaft and a gasket that surrounds the bush.
  • the bush of the present invention is produced from iron material that is treated by thermal nitration. Thus, while the mechanical properties of the bush such as wear resistance, strength, etc. are preserved, the production costs thereof are reduced.
  • Figure 1 – is the partial cross sectional view of a laundry washing machine.
  • Figure 2 – is the view of detail A in Figure 1.
  • Figure 3 – is the perspective view of the drum spider, the shaft and the bush related to an embodiment of the present invention .
  • the laundry washing and drying machine (1) comprises a cylindrical body (2), a tub (3) that surrounds the body (2), a drum spider (5) that has more than one support arm (4) enabling the movement of transmission elements such as electric motor, belt-pulley to be transferred to the body (2), a shaft (6) that extends from the drum spider (5) to the transmission elements and that transfers the movement of the transmission elements to the body (2), more than one bearing (7) that bears the shaft (6), a bush (8) that is disposed on the portion of the shaft (6) connected to the support arms (4) and a gasket (9) that is wrapped around the bush (8) so as to remain between the bush (8) and the tub (3).
  • transmission elements such as electric motor, belt-pulley
  • the bush (8) of the present invention is produced from iron material that is treated by thermal nitration. By means of the thermal nitration process, the chemical and mechanical wear resistance of the iron is improved. By means of the nitrogen used for the production of the bush (8), the iron hardens without any cooling process after the thermal nitration process.
  • the production method of the bush (8) consists of the following steps: - keeping the iron in a medium containing nitrogen between 520° C to 580° C for approximately 36 hours, - taking the iron out of the medium when the FE-N phase creating a white layer on the iron reaches the thickness of 15-20 microns and - using the iron with its surface coated with the FE-N phase for the production of the bush (8).
  • the bush (8) is produced from iron material treated by the thermal nitration process, having the same mechanical strength with the brass and better chemical strength than the brass.
  • the production costs of the bush (8) are decreased and environmentally-friendly products are developed.

Abstract

La présente invention concerne une machine à laver et sécher le linge (1) comprenant un corps cylindrique (2), une cuve (3) qui entoure le corps (2), un croisillon de tambour (5) équipé de plus d'un bras de support (4) permettant le mouvement d'éléments de transmission, tels qu'un moteur électrique, une courroie-poulie destinée à être transférée au corps (2), un arbre (6) qui s'étend du croisillon de tambour (5) aux éléments de transmission et qui transfère le mouvement des éléments de transmission au corps (2), au moins un palier (7) qui porte l'arbre (6), une douille (8) qui est disposée sur la partie de l'arbre (6) raccordée aux bras de supports (4) et un joint d'étanchéité (9) enveloppant la douille (8) de manière à rester entre la douille (8) et la cuve (3). La douille (8) est produite à partir d'un matériau de fer qui est traité par procédé de nitruration thermique. Un procédé de production de cette douille (8) par procédé de nitruration thermique est également décrit.
