Abstract
The invention discloses a high-precision gear and worm transmission mechanism with the reduced gear and worm transmission clearance and a regulating method thereof. The gear and worm transmission mechanism utilizes a split case, and a worm case and a gear case are manufactured respectively and are assembled by positioning cylindrical pins, a spring washer and clearance regulating and connecting screws according to the stated installation regulating method. Bidirectional regulation of the gear and worm transmission is realized, and the precision requirements for the center distance between a gear and a worm and orthogonal error of the axis are lowered. Since the clearance is reserved between the gear case and the worm case, the gear case and the worm case are connected together by the positioning cylindrical pins, the spring washer and clearance regulating and connecting screws, the positioning guide function of the positioning cylindrical pins, the elasticity action of the spring washer and fine regulation effect of the clearance regulating and connecting screws are integrated, clearance regulation difficulty is lowered, production cost is reduced effectively and the service life is prolonged, the reasonable transmission clearance reserved between the gear and the worm is guaranteed, and requirements for backlash and transmission efficiency are met.
Description
Technical field
The present invention relates to a kind of turbine and worm driving mechanism, relate in particular to a kind of highi degree of accuracy turbine and worm driving mechanism and installation adjusting method thereof that reduces the turbine and worm drive gap.
Background technique
As everyone knows, in the turbine and worm driving mechanism, the centre distance of turbine and worm and orthogonal axe error are the key factors of turbine and worm drive gap; Drive gap is too small can to increase resistance drop underneath drive efficient; Drive gap is crossed conference and is increased the backlash gap, if think rationally to reduce the turbine and worm drive gap, just must adjust the centre distance and the orthogonal axe error of turbine and worm; Guarantee to have rational drive gap between the turbine and worm, satisfy backlash gap and transmission efficiency requirement.Because the turbine and worm axis is at the two-dimensional space quadrature; Under the all-in-onecase situation; In case processing and assembling finishes, its centre distance can't change, and need reduce the occasion of turbine and worm drive gap at some; Adopt split type cabinet to be about to the worm screw case and turbine box is made respectively; Again two casings are assembled together, need the centre distance and the perpendicularity of the attachment face adjustment turbine and worm of two casings of processing grinding to guarantee to have rational drive gap between the two in this case, satisfy backlash gap and transmission efficiency requirement.The attachment face of two casings of this employing processing grinding guarantees that the mode that has rational drive gap between the turbine and worm exists some obviously not enough, one of which; The turbine and worm drive gap can only unidirectional from big to small adjustment, its two, the size of the attachment face of two casings of processing grinding is bad to be confirmed; Adjustment is wasted time and energy and is prone to waste product; Its three, when the turbine and worm drive gap increases because of wearing and tearing, be difficult to adjust once more because of this adjusting method is complicated.
Summary of the invention
The object of the invention overcomes deficiency of the prior art exactly, provides a kind of drive gap adjustable highi degree of accuracy turbine and worm driving mechanism and installation method thereof.The highi degree of accuracy turbine and worm driving mechanism that drive gap of the present invention is adjustable; Adopt split type cabinet to be about to the worm screw case and turbine box is made respectively; Two casings are assembled together by the installation adjusting method of regulation through setting circle pin, spring washer, attachment screw; Centre distance and quadrature error to turbine and worm in debuging process are adjusted; Rationally reduce the turbine and worm drive gap, realize guaranteeing to have rational drive gap between the turbine and worm, satisfy requirement backlash gap and transmission efficiency.
For solving the problems of the prior art, the highi degree of accuracy turbine and worm driving mechanism that drive gap is adjustable has adopted following technological scheme: the highi degree of accuracy turbine and worm driving mechanism that drive gap of the present invention is adjustable comprises: turbine, axle and bearing unit, turbine box; Worm screw and bearing unit; The worm screw case, 2 setting circle pins, 8 spring washers; Preset clearance between the turbine box worm screw case is adjusted and attachment screw in 8 gaps.Turbine box and worm screw case link together through setting circle pin, spring washer, gap adjustment and attachment screw.
The installation adjusting method of a kind of highi degree of accuracy turbine and worm driving mechanism that reduces the turbine and worm drive gap according to the invention is following:
The first step; The assembling of turbine box and worm screw case, with the turbine box that turbine, axle and bearing unit are housed and worm screw is housed and the worm screw case of bearing unit through 8 spring washers, 8 gaps are adjusted and attachment screw links together; Owing to have preset clearance between turbine box and the worm screw case; Gap adjustment and attachment screw press together through the Surface of action of pressure spring packing ring with worm screw and turbine, and at this moment, the centre distance of turbine and worm screw is less than the theoretical center distance; The Surface of action gap of worm screw and turbine is zero, and the quadrature error of turbine shaft and worm shaft is zero;
Second step; Manufacture the assembling and positioning straight pin; Join two positioning pin holes of work at turbine box and worm screw case joint, the installing and locating straight pin, the pin-and-hole of setting circle pin and turbine box adopts the slight interference transition fit; The setting circle pin adopts little gaps to cooperate with the pin-and-hole of scroll case, and the setting circle pin slides in the elastic force effect lower edge of spring washer to guarantee scroll case;
The 3rd step; The fine setting drive gap, all even loose gap adjustment and attachment screw, turbine box is done with the worm screw case and is separated relative movement under the elastic force effect of spring washer; The Surface of action of worm screw and turbine produces the gap; Come and go rotary worm and measure transmission resistance and backlash gap, repeatedly adjustment is measured and is had rational drive gap between turbine and the worm screw until reaching, and satisfies the requirement to backlash gap and transmission efficiency.
The invention has the beneficial effects as follows: highi degree of accuracy turbine and worm gearing that drive gap of the present invention is adjustable; Having overcome traditional manufacturing turbine and worm gearing adopts the method for controlling turbine and worm screw centre distance and orthogonal axe error and the attachment face that adopts two casings of processing grinding to guarantee to have between turbine and the worm screw the obvious deficiency of the method for rational drive gap; One of which; Realized that turbine and worm drive gap realize two-way adjustment, reduced required precision centre distance and the orthogonal axe error of turbine and worm screw; They are two years old; Because preset clearance between turbine box and the worm screw case; Turbine box and worm screw case link together through setting circle pin, spring washer, gap adjustment and attachment screw; The fine setting effect of the positioning and guiding effect of setting circle pin, the elastic reaction of spring washer and gap adjustment and attachment screw combines, and has greatly reduced gap adjustment difficulty; Its three, when turbine and worm drive gap increase because of wearing and tearing, because of this adjusting method is simply adjusted very easily once more; Its four, the new method of making highi degree of accuracy turbine and worm gearing is provided, can effectively reduce production costs and increase the service life.
