Abstract
The utility model discloses a center distance adjusting device for an open gear pair, and the center distance adjusting device comprises an adjusting disc. The adjusting disc is provided with one circle of adjusting bolt holes for adjusting bolts and one circle of tightening mounting holes for tightening bolts in a non-concentric-circle way; the adjusting disc is connected with a frame wallboard through one circle of adjusting bolts; a bearing assembly is mounted in the adjusting disc through one circle of tightening bolts; the bearing assembly is coaxially provided with a pinion; and the pinion is engaged and connected with a gearwheel. By using the device provided by the utility model, the pinion is enabled to approach the gearwheel in a step-by-step way when the adjusting disc is rotated by adopting a way of arranging the circle of holes for the adjusting bolts and the circle of holes for the tightening bolts on the adjusting disc in a non-concentric-circle way, so as to decrease the centre distance of a pinion pair. The device is simple in structure and low in processing cost and manufacturing cost, is easy to operate, and is safe and reliable, and the service life of equipment is improved.
Description
Technical field
The utility model belongs to heavy duty equipment manufacturing technology field, relates to a kind of open gear pair centre distance regulating device.
Background technique
Current, no matter be mining site machinery or maritime works equipment, manyly all use the large module gear transmission to carry out power output and transmit the heavy moment of torsion of the general slow-speed of revolution of this gear transmission; Adopt the open type transmission, the characteristics of this kind of drive are that power is big, and rotating speed is low, and the radial force of big small gear is big; The contact strength of gear is high, thereby the wear phenomenon of gear is more serious, and backlash increases after use a period of time; Transmission efficiency reduces, and noise increases, and the flank of tooth can accelerated wear test.So such kind of drive generally can increase the centre distance regulating mechanism of gear, adjust and reduce centre distance, make gear engagement better, transmission is more steady, thereby reaches the prolonged mechanical purpose in working life.And the centre distance regulating mechanism that adopts usually at present is generally screw or bolt propulsion mode; This mode advantage is convenient the adjusting; And problem is that leading screw or bolt have born the huge radial force of gear in the middle of equipment operation; Threads of lead screw was lost efficacy, cause centre distance increasing, serious meeting causes equipment accident.
Summary of the invention
The purpose of the utility model provides a kind of open gear pair centre distance regulating device; The employing leading screw or the bolt adjustment mode that exist in the existing technology have been solved; In the middle of equipment operation because the huge radial force of bearing gear; Threads of lead screw was lost efficacy, cause centre distance increasing, serious meeting causes the problem of equipment accident.
The technological scheme that the utility model adopted is; A kind of open gear pair centre distance regulating device comprises an adjustment dish, and non-concentric circle is provided with the adjustment bolt hole of a circle adjustment bolt and the tightening mounting hole of a circle tight fixed bolt on the adjustment dish; The adjustment dish is connected with the frame wallboard through a circle adjustment bolt; Through a circle tight fixed bolt bearing assembly is installed in the adjustment dish, bearing assembly is coaxially installed with small gear, and small gear and gearwheel are connected with a joggle.
The beneficial effect of the utility model is; The bolt that utilizes two groups of non-donuts to arrange is realized fixedly securing and regulating of small gear; Promptly utilize the frictional force tightening small gear of the fastening generation of inner ring bolt; Small gear is drawn close to gearwheel with step-by-step system when the adjustment disc spins, reduced the centre distance of gear pair.Easy operating, the replacing of no easily damaged parts, it is low to make maintenance cost, and Security and reliability are high, meet the housekeeping operation requirement of heavy duty equipment.
Description of drawings
Fig. 1 is the structural representation of the utility model open gear pair centre distance regulating device;
Fig. 2 is the adjustment rotary work principle schematic in the regulating device of the utility model.
Among the figure, 1. adjust bolt, 2. adjustment dish, 3. tight fixed bolt, 4. small gear, 5. gearwheel, 6. frame wallboard, 7. bearing assembly.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
With reference to Fig. 1, Fig. 2; The structure of the utility model open gear pair centre distance regulating device is; Comprise an adjustment dish 2; Non-concentric circle is provided with the adjustment bolt hole of a circle adjustment bolt 1 and the tightening mounting hole of a circle tight fixed bolt 3 on adjustment dish 2, and adjustment dish 2 is connected with frame wallboard 6 through a circle adjustment bolt 1, through a circle tight fixed bolt 3 bearing assembly 7 (comprising bearing support and bearing) is installed in the adjustment dish 2; Bearing assembly 7 is coaxially installed with small gear 4, and small gear 4 is connected with a joggle with gearwheel 5.
At two same adjustment dishes 2 of small gear 4 two ends symmetric arrangement, can increase the stability of small gear 4, see Fig. 1.Perhaps,, small gear 4 also can an adjustment dish 2 only be set when being cantilevered support structure at small gear 4 one ends.
A among Fig. 1 is a gear pair centre distance, and the s among Fig. 2 is the throw of eccentric of the standard pitch circle of two groups of bolts.
The working principle of the utility model structure is: with reference to Fig. 1, Fig. 2; Gearwheel 5 fixed-site; Small gear 4 is installed in the bearing assembly 7 and by tight fixed bolt 3 and is fixed on the adjustment dish 2, and tight fixed bolt 3 reduces the adjustment work of bearing assembly 7 like this through pretension and locking just no longer dismounting.When the sideshake that detects gear pair (gearwheel 5 and small gear 4) surpasses permitted value; Need reduce gear pair centre distance a; Then will all adjust bolt 1 pulls down; Adjustment dish 2 is rotated one or several adjustment bolt hole distance on frame wallboard 6, when meeting permitted value, reinstall and tighten whole adjustment bolts 1; In the time of after the gear pair wearing and tearing are a certain amount of, need adjusting once more; Equally adjustment dish 2 is rotated one or several adjustment bolt hole distance on frame wallboard 6; When meeting permitted value; Reinstall and tighten whole adjustment bolts 1, and the like, can realize the purpose of the centre distance of stepping adjustment gear pair.
The open gear pair centre distance regulating device of the utility model is employed in the mode in a circle hole of a circle hole and the tight fixed bolt 3 of the non-arranged in concentric circles adjustment bolt 1 on the adjustment dish 2; Small gear 4 is drawn close to gearwheel 5 with step-by-step system when 2 rotations of adjustment dish, reduced the centre distance a of gear pair.Single unit system is simple in structure, and the manufacturing cost is low, and easy operating is safe and reliable, has improved service life of equipment.
