Abstract[English]
A support roller for track-type agricultural machinery, comprising an axle retaining ring (100), a hub retaining ring (200), an adapter support member, and a rubber protective layer (400). The adapter support member is arranged between the axle retaining ring and the hub retaining ring and is composed of six arc-shaped support ribs (300), wherein the two ends of each support rib are connected to an inner wall of the hub retaining ring, and the middle part thereof is connected to an outer wall of the axle retaining ring, such that a hollowed-out structure is formed between the support ribs, the axle retaining ring and the hub retaining ring, which hollowed-out structure ensures the structural strength and enables communication between two sides of the adapter support member; each of the support ribs is connected to the outer wall of the axle retaining ring by means of an adapter rib (310), which prevents the formation of a narrow gap at the joint of the support rib and the axle retaining ring, and facilitates cleaning and maintenance; and the rubber protective layer is attached to an outer wall of the hub retaining ring by means of vulcanization, such that the outer wall of the hub retaining ring is protected and buffered, enabling shock absorption and load bearing, and contributing to the extension of the service life.[French]
L'invention concerne un galet guide de machine agricole de type à chenilles, comprenant une bague de retenue d'essieu (100), une bague de retenue de moyeu (200), un organe de support d'adaptateur et une couche de protection en caoutchouc (400). L'organe de support d'adaptateur est disposé entre la bague de retenue d'essieu et la bague de retenue de moyeu et est composé de six nervures de support en forme d'arc (300). Les deux extrémités de chaque nervure de support sont reliées à une paroi interne de la bague de retenue de moyeu, et leur partie centrale est reliée à une paroi externe de la bague de retenue d'essieu, de telle sorte qu'une structure évidée est formée entre les nervures de support, la bague de retenue d'essieu et la bague de retenue de moyeu, ladite structure évidée assurant la résistance structurale et permettant la communication entre deux côtés de l'organe de support d'adaptateur ; chacune des nervures de support est reliée à la paroi externe de la bague de retenue d'essieu au moyen d'une nervure d'adaptateur (310), ce qui empêche la formation d'un espace étroit au niveau de la jonction de la nervure de support et de la bague de retenue d'essieu, et facilite le nettoyage et l'entretien ; et la couche de protection en caoutchouc est fixée à une paroi externe de la bague de retenue de moyeu par vulcanisation, de sorte que la paroi externe de la bague de retenue de moyeu est protégée et amortie, ce qui permet une absorption des chocs et un support de charge, et contribue au prolongement de la durée de vie.[Chinese]
一种履带式农用机械支重轮，包括轮轴定位圈（100）、轮毂定位圈（200）、转接支承件及橡胶防护层（400）。转接支承件设置于轮轴定位圈与轮毂定位圈之间并由6条弧形支承筋（300）组成，支承筋的两端分别连接于轮毂定位圈内壁，中部连接于轮轴定位圈外壁，由此在支承筋与轮轴定位圈及轮毂定位圈之间形成镂空结构，该镂空结构在保证结构强度的同时，使转接支承件两侧贯通；支承筋通过转接凸棱（310）连接于轮轴定位圈外壁，可避免在支承筋与轮轴定位圈的连接处形成狭小间隙，便于进行清洗维护工作；橡胶防护层通过硫化附着于轮毂定位圈外壁，对轮毂定位圈外壁进行防护缓冲，起到防震承重作用，有利于延长使用寿命。
