Abstract
The invention relates to a speed reducer and belongs to the general machinery field. In order to regulate the axial gap of a rolling bearing, the rolling bearing of a speed reducer or other mechanical equipment is designed to be provided with a bearing cover, so as to prevent axial play and ensure sealing and dust prevention. The shortcomings of the above structure are that the cover can not be regulated; the processing precision is high; and the process is complex. The speed reducer is characterized in that inside threads or trenches are formed at two ends of a bearing hole of a box body of the reducer; and the axial gap of the bearing is regulated through the fit between an adjustment panel with outer threads and the inner threads to prevent the play of the bearing. The structure of the speed reducer has the advantages of large axial carrying capacity, reliable performance, high adjustment precision, large range, convenient installation and maintenance, and simple process. In addition, the number of parts is reduced, thereby reducing the production cost.
Description
Invention field
The present invention relates to a kind of speed reducer, belong to the universal machine field, (hereinafter to be referred as speed reducer).
Technical background
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.
Summary of the invention
Characteristics of the present invention are, the two ends in the bearing hole of speed reducer casing are processed with internal thread or ditch mortise, externally threaded adjustment plate and screw-internal thread fit are arranged by one, adjust the axial clearance of bearing, prevent that the string of bearing is moving.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.Reduce part in addition, therefore reduced 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 that the present invention has processing, installation and easy to maintenance quick, and axial carrying capacity is big, adjusts Accurately, the characteristics such as low cost of manufacture. Be suitable for various reductors and plant equipment. The also alternative spiral shell of using Bolt compresses the structure of bearing (ball) cover.
Claims (2)
1, a kind of speed reducer of 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.
