The invention relates to a worm gear head with oil storage chamber, which comprises a shell, a worm wheel and a worm. There is an oil hole in the center of the worm. The oil hole connects the inner worm and the outer worm. The threads of the inner worm are evenly spaced with multiple oil outlets. An oil storage box installation hole is arranged in the outer screw. The oil storage box installation hole is connected with the oil passage hole and is located in the oil storage box installation hole. Coaxially mounted an oil storage tank, with a zigzag or meter-shaped groove at the outer end of the tank, an oil inlet at the center of the zigzag groove or the meter-shaped groove, an oil outlet at the inner ring wall of the oil storage tank, and a spring and a steel ball at the corresponding oil outlet are installed in the oil storage tank. The steel ball connects one end of the spring and blocks the oil outlet, and the other end of the spring is fixed with the inner wall of the oil storage tank for storage. The inner wall of the oil tank mounting hole has an arc positioning groove corresponding to the steel ball. The worm gear head is equipped with an oil storage tank in the worm. The rotary oil storage tank can inject oil into the worm without disassembling the worm gear head. The operation is simple and fast.

带储油腔的蜗轮头
本专利技术属于阀门领域,涉及蜗轮头,尤其是一种带储油腔的蜗轮头。
技术介绍
阀门是流体输送系统中的控制部件,用于流体控制系统的阀门,从最简单的截止阀到极为复杂的自控系统中所用的各种阀门,其品种和规格相当繁多。现有的阀门的蜗轮头,壳体内蜗轮与蜗杆的啮合部位都是涂抹润滑油以保持其转动顺畅,但是需要定期打开蜗轮头补充润滑油,而实际使用中,打开蜗轮头是很麻烦且不实际的。因此需要一种可以不拆开蜗轮头就可以补充润滑油的新型蜗轮头。
技术实现思路
本专利技术的目的在于克服现有技术的不足之处,提供一种带储油腔的蜗轮头,不必拆开蜗轮头即可补充润滑油。本专利技术解决技术问题所采用的技术方案是:一种带储油腔的蜗轮头,包括壳体、蜗轮、蜗杆,蜗杆由内、外两段蜗杆啮合连接构成,内段螺纹部安装在壳体内,内段蜗杆与蜗轮啮合连接,在外段蜗杆安装手轮,在蜗杆内中心制有一过油孔,该过油孔连通内段蜗杆及外段蜗杆,在内段蜗杆上的螺纹处均匀间隔制有多个出油孔,出油孔连通过油孔,在外段螺杆内制有一储油盒安装孔,该储油盒安装孔与过油孔连通,在储油盒安装孔内同轴嵌装一储油盒,储油盒在安装孔内转动,在储油盒的外端面制有一字型或米字型槽,在一字型槽或米字型槽的中心制有一进油口,该进油口通过堵头密封,在储油盒的内端环壁上制有一出油口,对应出油口在储油盒内安装弹簧及钢球,钢球连接弹簧的一端且堵住出油口,弹簧的另一端与储油盒内壁固装,在储油盒安装孔的内壁对应钢球制有一弧形定位槽。而且,在储油盒安装孔的内端安装一吸油海绵。本专利技术的优点和积极效果是:1、本蜗轮头在蜗杆内安装一储油盒,旋转储油盒即可向蜗 ...
