Abstract
A worm mechanism for a worm gear speed reducer mainly comprises a worm body. A worm tooth is arranged in the middle of the worm body, a connecting section, a left bearing mounting section, an end cover mounting section and an input end are sequentially and axially arranged on the left side of the worm tooth on the worm body, the diameters of the connecting section, the left bearing mounting section, the end cover mounting section and the input end are gradually decreased, a thread section is arranged on the right of the end cover mounting section, a stop nut is connected onto the thread section in a threaded manner and abutted to the left bearing mounting section, and two sides of the worm tooth are respectively connected with an oil throwing plate in a sleeving manner. The worm mechanism has the advantages that mounting precision of a left bearing is greatly improved by the aid of the stop nut and a sleeve, and the high-precision worm mechanism is simple in structure, high in mounting precision, stable in transmission and fine in use effect.
Description
Technical field
The utility model relates to a kind of speed reducer, especially a kind of worm mechanism for worm-gear speed reducer.
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 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, and using effect is preferably for the worm mechanism of worm-gear speed reducer.
The purpose of this utility model is achieved by the following technical solution: mainly comprise a worm body, the centre of described worm body is provided with worm tooth; On described worm body, the left-hand axis of worm tooth is to the linkage section, 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.
As preferably, the length of described thread section is 3cm; The width of described stop nut is 2cm.
As preferably, on described worm body, the right side of worm tooth is provided with right bearing construction section; On described left bearing construction section and right bearing construction section, be provided with a sleeve for positioning bearing.
As preferably, 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 left bearing, have feature simple in structure, that installation precision is high, transmission is steady, using effect is good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: as shown in Figure 1, mainly comprise a worm body 1, the centre of described worm body 1 is provided with worm tooth 2; On described worm body 1, the left-hand axis of worm tooth 2 is to the linkage section 11, left bearing construction section 12, end cap construction section 13, the input end 14 that are disposed with diameter and diminish gradually; The right part of described end cap construction section 13 is provided with a thread section 15, has been threaded connection a stop nut 3 on this thread section 15; Described stop nut 3 is near described left bearing construction section 12; 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 there is linkage section in left side, and therefore the installation precision of whole bearing is higher.
The both sides of described worm tooth 2 are respectively socketed with one and get rid of oiled-plate method 4, two get rid of spacing between oiled-plate method 4 is slightly less than the diameter of worm gear in worm-gear speed reducer, in the time that worm screw is rotated, getting rid of oiled-plate method is thrown to the lubricant oil of bottom half 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.
The length of described thread section 15 is 3cm; The width of described stop nut 3 is 2cm.
On described worm body 1, the right side of worm tooth 2 is provided with right bearing construction section 16; On described left bearing construction section 12 and right bearing construction section 16, be provided with a sleeve 5 for positioning bearing; 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.
Described input end 14 is provided with flat key 6.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model is also not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation made, change and add or replace, all should belong to protection domain of the present utility model.
