Abstract
The invention relates to a backlash eliminating transmission structure of a gearbox input shaft, which comprises a first gear, a second gear, a bearing and a shaft; a motor is connected with a reducing gear, and is connected with a box body through a screw; the first gear and the second gear are meshed through end surface teeth, and are connected through the screw and a spring washer to form a gear group after being positioned by an installation shaft; one end of the gear group is connected with the reducing gear through the screw, and the other end of the gear group is arranged in a bearing hole of the box body after being provided with the bearing and is meshed with a third gear which is arranged on the next transmission shaft. According to the backlash eliminating transmission structure of the gearbox input shaft, the structure is simple and reasonable; when the end surface teeth are normally meshed and used, the two parts of straight teeth are offset, the offset state enables the two parts of straight teeth of a backlash eliminating gear to be respectively fitted with the positive and reverse directions of another meshing gear, so that a backlash eliminating effect is achieved; and the impact of component force on a spindle in a bevel transmission structure is prevented, so that the repair cost is reduced, and the product reliability is guaranteed.
Description
Technical field
The present invention relates to a kind of transmission case input shaft crack drive mechanism that disappears, the input shaft structural type of the crack transmission that is used in a kind of specifically transmission case disappearing between input shaft and the transmission shaft belongs to the Machining Technology field.
Background technique
In numerical control device, and since the needs of product performance, the frequent transmission case that needs to adopt various structural types and effect, but in order to ensure the product precision, the transmission accuracy of transmission case just becomes an extremely important technical order.Realize the crack transmission that disappears of transmission case, must ensure in the transmission case all has the higher crack drive mechanism that disappears of reliability between each transmission shaft, and the transmission input shaft of gap eliminating transmission case is owing to directly be connected with motor, and its design that disappears the crack mode seems particularly important.In gap eliminating transmission case commonly used, the normal transmission input shaft gap-eliminating structure form that adopts is that first helical gear is installed on the transmission input shaft, and second helical gear that is engaged with adopts gap-eliminating structure, thereby ensures the crack transmission that disappears of this group gear.Though this method can effectively ensure the gear-driven transmission accuracy of this grade, because the axial thrust load of helical gear in transmission process directly affacts the motor input shaft, very easily cause the damage of motor, reduced the reliability of equipment.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency; A kind of transmission case input shaft crack drive mechanism that disappears is provided, and this crack drive mechanism that disappears adopts the crack form that disappears of straight-tooth transmission, has avoided in the helical teeth drive mechanism component to the influence of main shaft; Reduce maintenance cost, ensured reliability of products.
According to technological scheme provided by the invention, a kind of transmission case input shaft crack drive mechanism that disappears comprises first gear, second gear, bearing, axle; Motor is connected with speed reducer, is connected with casing through screw; First gear and second gear mesh through the end face tooth, and connect to form gear train in back, installation shaft location through screw, spring washer; This gear train one end is connected with speed reducer through screw, and the other end is arranged in the bearing hole of casing behind the installation bearing, and with the 3rd gear engagement that is installed on next transmission shaft.
As further improvement of the present invention, be provided with end face tooth and straight-tooth respectively on said first gear, second gear; Through the end face tooth with first gear and second gear engagement.
As further improvement of the present invention, the straight-tooth on said first gear and second gear misplaces relatively.
Compared with present technology the present invention has the following advantages:
The present invention is simple and reasonable for structure, for fear of the damage of helical gear to motor, has adopted the disappear transmission case in crack of straight-tooth transmission, and this method is designed to two-part with one of them engagement spur gear, and through the engagement of end face tooth; In the course of working of this method; Need processing straight-tooth under the end face tooth slightly misplaces the state that meshes; And when end face tooth normal engaged is used; Two-part of straight-tooth have just formed dislocation, the two straight-tooth part that this dislocation makes clearance elimination gear respectively with forward and reverse applying of another engaging gear, thereby reach the crack effect that disappears; Avoided that component can reduce maintenance cost to the influence of main shaft in the helical teeth drive mechanism, ensured reliability of products.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1, the present invention mainly is made up of motor 1, speed reducer 2, first gear 3, second gear 4, bearing 5, axle 6, screw 7, spring washer 8, the 3rd gear 9 and casing 10.
Said motor 1 is connected with casing 10 through screw with after speed reducer 2 is connected; After first gear 3 and second gear 4 meshed through the end face tooth, installation shaft 6 was located, and connects to form gear train through screw 7, spring washer 8, and wherein spring washer 8 is used for locking; This gear train one end is connected with speed reducer 2 through screw, and the other end is arranged in the bearing hole of casing 10 after bearing 5 is installed, and meshes with the 3rd gear 9 that is installed on next transmission shaft, accomplishes transmission.
All be designed with end face tooth and straight-tooth simultaneously on first gear 3 and second gear 4; Work in-process; At first accomplish the processing of end face tooth in first gear 3 and second gear 4, through the end face tooth first gear 3 and second gear 4 are meshed then, and be uniformly distributed with three tooth flank pads, one pad; After making first gear 3 and second gear 4 turn over several angle relatively, the reprocessing straight-tooth; When in actual time, take out pad, the end face tooth on first gear 3 and second gear 4 is directly meshed; Straight-tooth on the win gear 3 and second gear 4 is misplaced relatively; When with the engagement of the 3rd gear 9, the straight-tooth part on first gear 3 and second gear 4 respectively with the 3rd gear 9 on adjacent two teeth applying, so no matter main shaft clockwise and anticlockwise; First gear 3 and second gear 4 all mesh with the 3rd gear 9 no gaps, thereby have ensured the crack transmission that disappears of transmission case input shaft.
