Abstract
The utility model relates to double-gear driving device of roll grinder carriages, which relates to a drive mechanism of roll grinders. The device comprises a motor and a turbine pair, and further comprises output gears and a racks, which are fixed on a turbine pair output shaft, and is characterized in that the output gears are two beveled gears with the same dimension sleeved on an output shaftsplined slot, the two output beveled gears are respectively engaged with a left and a right side driven beveled gears, the left and the right driven beveled gears are fixed on a left and a right driving shafts, a left and a right spur gears with the same dimension are respectively fixed on the other ends of the two driving shafts, the left and the right spur gears are respectively engaged with theracks on the corresponding positions of the racks, a disc-shaped belleville spring fixed by a screw bolt covers the end surface of an output shaft of the turbine pair, and the circular excircle of the belleville spring is pressed on the end surfaces of the outer ends of the output beveled gears. The device has the advantages that the output beveled gears are pressed by the belleville spring, andthe axial pressing moving force is generated to the left and the right driven beveled gears, and two spur gears are reversely pressed with the contacting surface of the racks and are contacted with the racks in a gapless mode, thereby the gapless reversing driving is realized during the reversing of the output gears.
Description
Technical field:
The utility model relates to the roll grinder transmission mechanism.
Background technology:
Roll grinder emery wheel planker walking is at present implemented emery wheel and is moved grinding roller, emery wheel planker transmission mechanism is by the driven by motor reducer of turbodrill, fix the tooth bar engagement of spur gear and planker on its output shaft and implementing transmission, the wheel and rack transmission generally all has the backlash, and planker is a bidirectional-movement, therefore gear rotation move to the time, this backlash causes tooth-formation of gear that the idle running gap is arranged between the profile of tooth of tooth bar, that is to say noncontinuity commutation transmission.
The wheel grinding roll, roll outer surface microcosmic from the section profile is an arc curve, generally speaking if the always unidirectional walking grinding of emery wheel, its sectional curve is basic identical, but unidirectional abrasive grinding wheel backhaul is that idle stroke influences working (machining) efficiency, if two-way grinding, backhaul starting point and former journey end point error are caused in the backlash during backhaul, from the variant grinding accuracy that influences of sectional curve track.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of roll grinder planker bidentate wheel drive unit is provided.
Scheme of the present utility model is: device comprises that motor, turbine are paid, turbine is paid output gear, tooth bar fixing on the output shaft, it is characterized in that output gear is two helical gears that are linked in two same sizes on the output shaft spline, two output helical gears mesh with the passive helical gear of and arranged on left and right sides respectively, left and right passive helical gear is fixed on the left and right power transmission shaft, two power transmission shaft other ends are fixed the left and right spur gear of same size respectively, and left and right spur gear is respectively in tooth bar relevant position and tooth bar engagement; Turbine is paid the disc butterfly spring that the output shaft end face covers a bolting, and the circular cylindrical compressing of this butterfly spring is exported on the helical gear end face in the outer end.
Advantage of the present utility model is: the output helical gear is subjected to butterfly spring pressure, make left and right passive helical gear produce axially compressing locomotivity, also just impel two commutating tooth wheel and rack contact-making surfaces oppositely to oppress the contact of no gap, thereby reach the transmission that commutates of no gap during the output gear commutation.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
Structure of the present utility model comprises that motor, turbine are paid (1), turbine is paid output gear, tooth bar (6) fixing on (1) output shaft, it is characterized in that output gear is two helical gears that are linked in two same sizes on the output shaft spline, two output helical gears (2) mesh with the passive helical gear of and arranged on left and right sides respectively, left and right passive helical gear (3) is fixed on the left and right power transmission shaft, two power transmission shaft other ends are fixed the left and right spur gear (5) of same size respectively, and left and right spur gear (5) is respectively in tooth bar (6) relevant position and tooth bar (6) engagement; Turbine is paid the disc butterfly spring (4) that (1) output shaft end face covers a bolting, and the circular cylindrical compressing of this butterfly spring (4) is on the end face of outer end output helical gear (2).
Owing to adopt the helical gear transmission, when butterfly spring (4) elasticity compressing two output helical gear (2), the length travel position of output helical gear (2) on spline forces the passive helical gear that is engaged with slightly to rotate, and two passive helical gears are to be divided in output helical gear (2) both sides, thereby switched in opposite, also drive relatively reverse rotation of left and right spur gear (5), until the engagement that reclines mutually of spur gear profile of tooth and tooth bar (6), also with regard to the unidirectional backlash of having eliminated, with respect to two-way no gap.
When planker is walked left, left spur gear carry-over moment, left spur gear servo-actuated; When planker is walked left, left spur gear carry-over moment, left spur gear servo-actuated.So the reverse walking of planker can not produce the idle running amount of wheel and rack (6), improve grinding accuracy.
