Drive axle of rubber tired gantry crane

轮胎式门式起重机驱动车桥

Abstract

本实用新型公开的这种轮胎式门式起重机驱动车桥,包括传动轴和连接于传动轴长度方向中间位置处的链轮法兰,链轮通过连接于传动轴上的链轮法兰及安装于链轮上的链条与起重机的驱动机构连接以驱动整机运行。传动轴上链轮的两侧对称连接有轴承及轴承座,轴承座与起重机的驱动车架连接以支撑整机,传动轴的两端对称连接有轮辋法兰,轮辋法兰与车轮的轮辋连接以将驱动机构的动力传递给车轮来实现整机运行。取消了现有技术的桥壳、桥包复杂结构,从而克服了因桥壳、桥包结构带来的相应缺陷,具有结构简单紧凑、性能可靠、重量轻、加工维修方便和降低制造成本的优势。
The utility model discloses a drive axle of a rubber tired gantry crane. The drive axle comprises a drive shaft and a chain wheel flange connected to the middle of the drive shaft in the length direction, wherein a chain wheel is connected with a drive mechanism of the crane through the chain wheel flange connected onto the drive shaft and a chain mounted on the chain wheel so as to drive the whole machine to operate; bearings and bearing blocks are symmetrically connected to two sides of the chain wheel on the drive shaft, and the bearing blocks are connected with a drive frame of the crane so as to support the whole machine; rim flanges are symmetrically connected to two ends of the drive shaft and connected with rims of wheels so as to transfer power of the drive mechanism to the wheels to achieve operation of the whole machine. A complex structure comprising an axle housing in the prior art is omitted, so that corresponding defects caused by the axle housing structure are overcome, and the drive axle of the rubber tired gantry crane has the advantages that the structure is simple and compact, the performance is reliable, the weight is light, the manufacture and maintenance are convenient and the manufacture cost is reduced.
