Abstract
The utility model relates to an elastic base gap eliminating mechanism for worm wheel and worm. An elastic floor with an elastic groove is used as a worm mounting floor. The elastic groove size is adjusted to drive the worm micro movement, so as to adjust the clearance between the worm wheel and the worm, thereby realizing clearance elimination aim. The utility model is simple in structure, convenient in adjustment, obvious in clearance elimination effect after adjusting, comfortable in worm wheel and worm movement without sloshing, and can greatly improve transmission stability, and is suitable for worm wheel and worm transmission of various precision machines.
Description
Technical field
The present invention is an elastic base worm and gear anti-backlash mechanism, is mainly used in the worm gearing of various mechanisms, in the transmission device of especially various optical precision adjustment racks.
Background technique
The worm and gear transmission is generally used for transmitting movement and power between alternating axis.It is big that it has a velocity ratio, stable working, noise is low, compact structure, can self-locking etc. advantage.Because the distinctive big speed ratio advantage of worm and gear makes worm and gear have great practical value at the aspects such as raising adjustment precision of optical adjusting frame.At present, worm-and-wheel gear commonly used relies on the profile of tooth that changes worm gear or worm screw to improve quality of fit between the worm and gear usually, as being provided with on flexible slot or spiral chute, the outer surface worm screw at worm gear gear teeth root and method such as semicircle flute profile ball orbit groove being set on the inner and outer surface of worm gear.There is obstructed usefulness in such structure and makes than problems such as difficulties.In the application of reality, often on mechanical structure, do not design special gap-eliminating structure, and mainly be to lean on the machining accuracy of worm and gear to guarantee usability.Yet, because the restriction of level of processing, make the very high worm and gear of quality of fit certain degree of difficulty is arranged, and in use because the mutual wearing and tearing of worm and gear also can cause the gap enlargement between the worm and gear, thereby the worm and gear axial runout usually appears in actual use, the worm and gear wearing and tearing accelerate to cause phenomenons such as whole transmission device stability decreases.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned the deficiencies in the prior art, a kind of elastic base gap eliminator for worm and wormwheel is provided, this device should be able to reach the purpose of regulating micro-gap between the worm and gear, and require to regulate easy, low cost of manufacture, advantages of higher stability is arranged, be applicable in the transmission device of various mechanisms, in the transmission device of especially various optical adjusting frames.
The basic thought of technical solution of the present invention is:
Utilize an elastic bottom plate of opening elastic groove to drive the worm screw that is mounted thereon and radially realizing micro displacement, thereby regulate the gap between the worm and gear, reach the purpose in the crack that disappears.The adjusting of elastic bottom plate relies on the screw on the plate to realize.
It is as follows that technology of the present invention solves concrete scheme:
A kind of elastic base worm and gear anti-backlash mechanism that is applied to multiple precision optical machinery, it is characterized in that this anti-backlash mechanism is that described elastic bottom plate side has an elastic groove, an adjusting screw is goed deep in the described elastic groove by a tapped hole of the bottom surface of described base plate.
Described worm gear and worm component include bearing support, baffle plate and the double-row radial ball bearing of worm gear, worm screw and installation worm screw.The worm screw two ends are installed together also integral installation on elastic bottom plate by ball bearing and bearing support respectively.Baffle plate is used to prevent that ball bearing is in axial translation.
Advantage of the present invention:
Elastic base worm and gear anti-backlash mechanism of the present invention is simple in structure, and the micro-displacement that can carry out radially worm screw in installation or using process is regulated, thereby reaches the purpose of regulating gap between worm gear and the worm screw, has the crack of disappearing function.Apparatus of the present invention easy processing, low cost of manufacture, easy to adjust, regulating effect is good, and no backlash phenomenon has very strong use value.

Embodiment
See also Fig. 1, Fig. 2 earlier, and in conjunction with Fig. 3, Fig. 1 is the structural representation of elastic base worm and gear anti-backlash mechanism of the present invention, as seen from the figure, elastic base worm and gear anti-backlash mechanism of the present invention, comprise the elastic bottom plate 102 of being with adjusting screw 101, elastic bottom plate 102 has the flat board of an elongated slot for the side, near the base plate of fluting one end a tapped hole 1021 is arranged.Adjusting screw 101 is installed on the tapped hole 1021, and rotation adjusting screw 101 can make the gap enlargement of elastic groove 1022 or dwindle, and realizes the purpose of fine setting.On the elastic bottom plate 102 screw hole is arranged, utilize bearing support screw 109 two bearing supports 108 can be separately fixed on the elastic bottom plate 102.Bearing support 108 has the structure of through hole for the center, is installed in the hole of bearing support 108 after upper bearing (metal) 105 is overlapped at the two ends of worm screw 103 respectively again.Install and fix baffle plate 107 at the two ends of bearing support 108 respectively with baffle plate screw 106 then, prevent that worm screw 103 and bearing 105 are in radial slippage.But last worm screw 103 and elastic adjusting mechanism integral installation thereof are used with worm gear 104 in place.After overall structure installs, utilizing adjusting screw 101 to regulate the stretching of elastic grooves 1022 or shrink can make elastic base 102 micro-strains and drive the bearing support 108 that is installed on the elastic bottom plate 102 and moving radially, thereby driving worm screw 103 moves, make the position that is adjusted to a best between worm gear 104 and the worm screw 103, reach the purpose of eliminating micro-gap.Because elastic groove 1022 width that elastic bottom plate 102 is opened for its side of stiffener plate are less, when regulating, there is adjusting screw 101 to hold out against, so whole mechanism stability can be not an elastic structure and being affected because of base.
Show through the reality use, elastic base worm and gear anti-backlash mechanism of the present invention is simple in structure, easy to adjust, the crack effect that disappears after the adjusting is obvious, the worm and gear comfortable nothing of moving is rocked, be applied on the controlling mechanism of optical precision optical machinery adjustment rack, do not have backlash through measuring, reseting precision≤1/8000 (whole process) is applicable in the worm gearing of various precision optical machineries.
