Background technique
At present, the structure of worm-gear speed reducer is more complicated, in the time that the various component of worm-gear speed reducer are installed, because part is more, all there is tolerance in each component, cause the installation precision of whole speed reducer poor, and then the operation of speed reducer is exerted an influence in making and installation process; In addition, speed reducer needs driven by motor preheating conventionally, and lubricant oil in speed reducer is at bottom half, and the short time cannot be lubricated whole worm gear machine worm tooth in time; Therefore, each component in speed reducer are improved, improve the installation precision of worm mechanism, and increase it and get rid of functional oil, contribute to improve the operational effect of worm-gear speed reducer.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of simple, firm, long service life, transmits worm-gear speed reducer stably.
The purpose of this utility model is achieved by the following technical solution: comprise casing, worm gear, worm screw; The two ends of described worm screw are socketed with bearing; Described bearing is fixed on casing by bearing (ball) cover; The centre of described worm screw is provided with the worm tooth engaging with worm gear; On described worm screw, the left-hand axis of worm tooth is to the left connection part, left bearing construction section, end cap construction section, the input end that are disposed with diameter and diminish gradually; The right part of described end cap construction section is provided with a thread section, has been threaded connection a stop nut on this thread section; Described stop nut is near described left bearing construction section; The both sides of described worm tooth are respectively socketed with one and get rid of oiled-plate method, and two get rid of distance between oiled-plate method equals the diameter of worm gear.
The described oiled-plate method that gets rid of gets rid of oiled-plate method body by the identical semicircle of two structures and is bolted and forms; The described surface uniform that gets rid of oiled-plate method body is provided with the detent projection of evagination.
On described worm screw, the right side of worm tooth is provided with right connection part and right bearing construction section; Described in installing on described left connection part and right connection part, get rid of oiled-plate method; On described left bearing construction section and right bearing construction section, be provided with a sleeve for positioning bearing.
Described bearing (ball) cover is fixed by screws on casing, and seals mutually by oil sealing and worm screw; Between described bearing (ball) cover and casing, be also provided with adjustment pad.
The length of described thread section is 3cm; The width of described stop nut is 2cm.
Described input end is provided with flat key.
The beneficial effects of the utility model are: utilize stop nut and sleeve, greatly improved the installation precision of bearing, have feature simple in structure, that installation precision is high, transmission is steady, using effect is good, the life-span is long.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of worm screw described in the utility model.
Fig. 3 is the structural representation that gets rid of oiled-plate method described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: as shown in Figure 1, 2, comprise casing 1, worm gear 2, worm screw 3; The two ends of described worm screw 3 are socketed with bearing 4; Described bearing 4 is fixed on casing 1 by bearing (ball) cover 5; The centre of described worm screw 3 is provided with the worm tooth 31 engaging with worm gear 2; On described worm screw 3, the left-hand axis of worm tooth 31 is to the left connection part 32, left bearing construction section 33, end cap construction section 34, the input end 35 that are disposed with diameter and diminish gradually; The right part of described end cap construction section 34 is provided with a thread section 36, has been threaded connection a stop nut 6 on this thread section; Described stop nut 6 is near described left bearing construction section 33; The both sides of described worm tooth 31 are respectively socketed with a diameter that gets rid of oiled-plate method 7, two and get rid of distance between oiled-plate method 7 and equal worm gear 2; Because the diameter of end cap construction section is less than the diameter of left bearing construction section, in the time that bearing is arranged on left bearing construction section, its right side is propped up and is located by stop nut, and the left side section of being connected props up, and therefore the installation precision of whole bearing is higher.
The described oiled-plate method 7 that gets rid of gets rid of oiled-plate method body 71 by the identical semicircle of two structures and fixedly forms by bolt 72; The described surface uniform that gets rid of oiled-plate method body 71 is provided with the detent projection 73 of evagination, as shown in Figure 3; In the time that worm screw is rotated, get rid of oiled-plate method and the lubricant oil of bottom half is thrown on the gear of worm gear, improve the lubricity of worm gear and worm screw, contribute to reduce the wearing and tearing between worm gear and worm tooth, improve the life-span of worm-gear speed reducer.
On described worm screw 3, the right side of worm tooth 31 is provided with right connection part 37 and right bearing construction section 38; Described in installing on described left connection part 32 and right connection part 37, get rid of oiled-plate method 7; On described left bearing construction section 33 and right bearing construction section 38, be provided with a sleeve 8 for positioning bearing 4; The common positioning bearing of sleeve and stop nut, can avoid bearing directly to contact with linkage section and cause the wearing and tearing of linkage section, and stop nut and sleeve can change, and is convenient to maintenance.
