Description

一种双电机驱动的行走辊 技术领域
本发明属于草坪养护机械领域，尤指一种双电机驱动的行走辊。
背景技术
传统的行走辊，是靠发动机或电机通过链条或皮带驱动行走辊轴，行走辊内部配有内置差速装置或棘轮棘爪装置；也有发动机或电机通过外差速装置驱动行走辊轴，还有采用内置一个外转子电机通过内置差速装置或棘轮棘爪装置驱动行走辊。这些结构方式由于机械传动机构和差速装置的存在，结构复杂，噪音大，传递效率不高，维修保养繁琐。
发明内容
本发明的目的在于提供一种结构更加简单、维护保养更加方便的双电机驱动的行走辊。
为达成上述目的，本发明采用以下技术方案：
一种双电机驱动的行走辊，包括左辊和右辊，该左辊和该右辊之间设有间隙，在该左辊和右辊的中心轴线处设支撑轴，该支撑轴的左侧套固与该左辊连接的左外转子电机，在该支撑轴的右侧套固与该右辊连接的右外转子电机。
所述左外转子电机与所述右外转子电机结构相同，该左外转子电机和右外转子电机包括外端盖、内端盖、定子总成及外转子，定子总成的中心通孔设有键槽与支撑轴键连接，该定子总成与外端盖和内端盖之间分别设置轴承一，外转子与该外端盖及该内端盖固接，该外端盖的外圈与该左辊和右辊的内壁固连的环形板通过螺栓连接。
两所述环形板对应焊接在左辊和右辊内壁上，所述环形板的内面上焊接与所述螺栓螺接的螺母，或在该环形板上攻有螺丝孔。
靠近左辊与右辊之间的间隙处的支撑轴上分别套设结构相同的左支撑件和右支撑件，该左、右支撑件包括左、右支撑板和轴承二，该左、右支撑板分别焊接在该左辊和该右辊的内壁上，其中心分别套设轴承二并靠支撑轴中间台阶定位。
所述左外转子电机和右外转子电机的外侧的支撑轴上分别设置锁紧套，该支撑轴两端设置扁位并通过该扁位固定在机架上。
所述左外转子电机和右外转子电机由控制器控制其同步和不同步旋转、不同向旋转，使该行走辊实现直线行走、转弯行走和原地转向的功能。
本发明的有益效果：本发明的左辊和右辊分别采用电机直驱模式，通过电子差速，即可实现行走辊的直线行走及转弯行走等功能。

本发明的支撑轴通过键连接整个定子总成，整体保持静止状态，通电时，通过固连外转子的外端盖带动相应的辊转动。辊最内侧焊接支撑板，作为辊的内部支撑；外侧焊接环形板，环形板上攻丝或内面焊接螺母，方便电机从外侧装入并固定。
所述左外转子电机和右外转子电机由控制器控制其同步和不同步旋转、不同向旋转，使该行走辊实现直线行走、转弯行走和原地转向的功能。本发明为实现转弯，由电子控制器取代机械差速机构。
直线行驶时，左辊、右辊同时由各自电机等速驱动，双辊保持前进，操作者通过机器扶手辅助方向，控制机器前进状态。
当需要左转弯时，通过机器扶手控制，左辊断电或减速，右辊速度保持不变或加速，从而实现机器左转；当需要右转弯时，通过机器扶手控制，右辊断电或减速，左辊速度保持不变或加速，从而实现右转。
当需要原地掉头时，两个电机断电而由外力驱动，或者一个电机正转、一个电机反转，从而实现原地转向。
