Abstract
The utility model relates to a speed reducer, which belongs to the mechanical field. Bearing glands are generally designed on the rolling bearings of the speed reducer and a mechanical equipment in order to adjust the axial clearance of the bearing, thus to prevent the axial hunting and be sealed and dustproof. The structure has the deficiencies that the gland can not be adjusted, the processing precision is high, and the process is complex. The utility model is characterized in that internal threads or grooves are arranged at both ends in the bearing hole of the box body of the speed reducer, an adjusting plate with an internal thread is matched with the internal thread, to adjust the axial clearance of the bearing to prevent the hunting of the bearing. The structure of the utility model has the advantages that the axial bearing capacity is large, the performance is reliable, the range is large, the installation and the maintenance are convenient, and the processing is simple.
Description
Technical field
The utility model relates to a kind of speed reducer, belongs to the universal machine field, (hereinafter to be referred as speed reducer).
Background technique
The rolling bearing of speed reducer and machinery for adjusting the axial clearance of bearing, will design bearing gland, usually to prevent axial motion and sealing and dustproof.The deficiency of said structure is that gland can not be adjusted, and is the machining accuracy height again, complex process.
The model utility content
The purpose of this utility model provides and a kind ofly adopts union (screwed)bonnet (UB to adjust bearing axial clearance and speed reducer easy to adjust is installed.Usually, the bearing fit up gap of speed reducer is the seam degree of depth by method of measurement processing gland, compresses gland by bolt and satisfies its bearing axial clearance.This method exists complex process, quality of fit difference and the maintenance of wearing and tearing back to adjust deficiencies such as difficulty.
The utility model has solved the problems referred to above, its technical characterstic is: the two ends in the bearing hole of speed reducer body, be processed with internal thread and groove, and by one externally threaded adjustment gland and body screw-internal thread fit are arranged, adjust the axial clearance of bearing, prevent axial motion.It is big that this structure has axial carrying capacity, and reliable performance is adjusted the precision height, and scope is big, and installation and maintenance are convenient, and processing is simple.Because the axial clearance of bearing has been adjusted to best interstice coverage, therefore improved the working life and the usability of bearing.Also reduced simultaneously cost of production.
Description of drawings

Fig. 3 is a speed reducer output shaft external part structure cutaway view Amplified image
Among the figure, 1 bearing, 2 blind hole end caps, piece is bored in 3 stop partially, 4 stop columns, 5 internal threads, 6 bodies, 7 through hole end caps.
Embodiment
From accompanying drawing, speed reducer is by body, gear, and bearing and axle are formed.Bearing hole two ends at body 6 are processed with internal thread 5, cooperate with it by being processed with externally threaded blind hole end cap 2 and through hole end cap 7, and the axial clearance of adjustment and bearing 1, thus the string that has prevented bearing 1 is moving.Guaranteed the rational axial clearance of bearing.From accompanying drawing, blind hole end cap 2 and through hole end cap 7 all are equipped with an amount of loosening stop of end cap that prevents and bore piece 3 and stop column 4 partially.After above-mentioned two end cap was adjusted to the right place, piece 3 was bored in turn stop partially, made stop column 4 protruding internal threads 5 with body 6 end tight.Therefore, guaranteed the proper functioning of speed reducer and machinery.When mechanical wear occurring and need adjust, piece 3 is bored in cycle stop partially, and stop column 4 is in loosening state, with above-mentioned two end cap 2; 7 adjust, to zone of reasonableness.To reach the purpose of maintaining.
It is simple to the utlity model has processing, installation and easy to maintenance quick, and axial carrying capacity is big, Adjust accurately the characteristics such as low cost of manufacture. Be suitable for various reductors and plant equipment. Also can replace Substitute the structure that bolt compresses bearing (ball) cover.
Claims (2)
1. the speed reducer of an adjustable bearing end cap is by body, gear, and bearing and axle are formed, and it is characterized in that: be processed with internal thread (5) in the bearing hole of body (6), be used for adjusting the axial clearance of bearing.
2. according to the described speed reducer of claim 1, it is characterized in that: be furnished with in the above-mentioned bearing hole and be processed with externally threaded blind hole end cap (2) and through hole end cap (7).
