Abstract
The utility model discloses a gear clearance eliminating device which comprises a box body, an input shaft gear, a transmission shaft gear and an output shaft gear are matched and transmitted at any angle and arranged inside the box body, a transmission bearing is arranged at the input end of a transmission shaft on one side of the transmission shaft gear, a bearing cover is arranged on a portion, at the outer end of the transmission bearing, of the box body, an adjusting gasket is arranged between the bearing cover and the transmission bearing, and the adjusting gasket is used for adjusting an relative meshing clearance of the transmission shaft gear and the input shaft gear and an relative meshing clearance of the transmission shaft gear and the output shaft gear. The adjusting gasket on one side of the box body is used as an adjusting mechanism for enabling gear transmission to reach an interference state, the service life of the gear transmission in various devices can be greatly prolonged, maintenance cost is reduced, and production efficiency is increased.
Description
Technical field
The utility model relates to a kind of elimination gear clearance device, belongs to gear technique fields such as accurate speed reducer.
Background technique
Gap between the driving gear of equipment such as speed reducer of the prior art is fixed, and that is to say after casing machines it is what just can not change.So just cannot change the gap between gear, thereby use the gap change between backgear big for a long time, wearing and tearing increase, and machining accuracy reduces, the manufacturing efficiency step-down, and the while also greatly reduces the working life of speed reducer.
The model utility content
The utility model purpose is to provide a kind of elimination gear clearance device at the defective that prior art exists.
The utility model adopts following technological scheme for achieving the above object: a kind of elimination gear clearance device, comprise casing, and be provided with input shaft gear, shaft gear and the output shaft gear of arbitrarily angled cooperation transmission in the described casing; The transmission shaft input end of described shaft gear large end face one side is provided with first drive bearing, and the casing of the described first drive bearing outer end is provided with the clutch shaft bearing lid; Be provided with first between described clutch shaft bearing lid and described first drive bearing and adjust pad; The transmission shaft output terminal of described shaft gear small end face one side is provided with second drive bearing, and the casing of the described second drive bearing outer end is provided with second bearing cap; Be provided with second between described second bearing cap and described second drive bearing and adjust pad; Described first, second adjust pad be used for adjusting described shaft gear respectively with the relative back lash of described input shaft gear and described output shaft gear.
The beneficial effects of the utility model: the adjustment pad of casing side of the present utility model makes gear transmission reach the interference state fully as regulating mechanism, can prolong working life, the minimizing maintenance cost of various device middle gear transmission greatly, increases manufacturing efficiency.Carry out grinding disposing after assembling is finished again and can prolong gear transmission service life of equipment raising gear quality of fit greatly.
Description of drawings
Fig. 1 structural representation of the present utility model.
Embodiment
Shown in Figure 1, for a kind of elimination gear clearance device, comprise casing 7, be provided with input shaft gear 1, shaft gear 5 and the output shaft gear 6 of arbitrarily angled cooperation transmission in the described casing 7; The input end of the transmission shaft 4 of described shaft gear 5 large end faces one side is provided with first drive bearing (not drawing among the figure), and the casing 7 of the described first drive bearing outer end is provided with clutch shaft bearing lid 30; Be provided with first between described clutch shaft bearing lid 30 and described first drive bearing and adjust pad 20; The output terminal of the transmission shaft 4 of described shaft gear 5 small end faces one side is provided with second drive bearing (not drawing among the figure), and the casing 7 of the described second drive bearing outer end is provided with second bearing cap 31; Be provided with second between described second bearing cap 31 and described second drive bearing and adjust pad 21; Described first, second adjust pad 20,21 be used for adjusting described shaft gear 5 respectively with the relative back lash of described input shaft gear 1 and described output shaft gear 6.
After gear transmission equipment used a period of time, it is big that the gap of the input shaft gear 1 of this gear transmission equipment, shaft gear 5 and output shaft gear 6 becomes.At this moment, can adjust relative position gap between gear by adjusting adjustment pad 2 on the transmission shaft 4, make it reach the interference state fully, publish in instalments by a motor and to carry out break-in at this gear transmission equipment and make to becoming the best fit state, just can reach almost nil Spielpassung, increase the service life, reduce production costs.Carry out grinding disposing after assembling is finished again and can prolong gear transmission service life of equipment raising gear quality of fit greatly.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
