Abstract
The utility model relates to a hollow resonant reduction gear with a deep groove ball bearing. The hollow resonant reduction gear comprises a resonant speed reducer, a hollow input shaft and the deep groove ball bearing, wherein the hollow input shaft is arranged in the resonant speed reducer; a bearing fixing assembly is arranged on the resonant speed reducer; the deep groove ball bearing is arranged between the hollow input shaft and the bearing fixing assembly; the bearing fixing assembly comprises a bearing base and a bearing pressure plate; and the bearing base and the bearing pressure plate are used for fixing the two ends of the deep groove ball bearing respectively. According to the hollow resonant reduction gear with the deep groove ball bearing disclosed by the utility model, the deep groove ball bearing is fixed on the resonant speed reducer through the bearing fixing assembly, so that the overall firmness and the stability of the harmonic speed reducer are ensured; and during installation, use requirements can be met without excessive adjustment, so that the installing time is saved, and convenience is provided for future overhaul and maintenance.
Description
Technical field
The utility model relates to a kind of harmonic speed changer, specifically a kind of stabilized structure, the hollow type harmonic speed changer with deep groove ball bearing being convenient to install.
Background technique
Harmonic speed reducer in application because structure or specific (special) requirements, need in the middle of retarder, cross line or pass through other part, therefore the input shaft of retarder need to be hollow design, need when mounted simultaneously synchronous pulley to drive, in this case, reducer input shaft needs when mounted to increase by one group of deep groove ball bearing and supports input shaft, to guarantee the steadiness of input shaft, cause harmonic speed reducer comparatively complicated loaded down with trivial details when assembling, and higher to the installation requirement of part, the adjustment that is not easy to post facility is overhauled.
The model utility content
The utility model purpose is the hollow type harmonic speed changer with deep groove ball bearing that a kind of stabilized structure is provided in order to overcome the deficiencies in the prior art, is convenient to install.
For achieving the above object, the technical solution adopted in the utility model is: a kind of hollow type harmonic speed changer with deep groove ball bearing comprises harmonic speed reducer, hollow input shaft, deep groove ball bearing; Described hollow input shaft is arranged in the harmonic speed reducer; Be provided with the bearing fixing-assembly on the described harmonic speed reducer; Described deep groove ball bearing is arranged between hollow input shaft and the bearing fixing-assembly; Described bearing fixing-assembly comprises bearing support and bearing plate; Described bearing support and bearing plate are fixed the two ends of deep groove ball bearing respectively.
Preferably, on the excircle of described hollow input shaft, be provided with back-up ring near the deep groove ball bearing place.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
The hollow type harmonic speed changer with deep groove ball bearing of the utility model scheme, by the bearing fixing-assembly deep groove ball bearing is fixed on the harmonic speed reducer, guaranteed the firm and stable of harmonic speed reducer integral body, and when using installation, need not the requirement that too much adjustment can be satisfied use, save the installation time, and be convenient to the inspection and maintenance in equipment later stage.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the sectional view of a kind of hollow type harmonic speed changer with deep groove ball bearing of the present utility model;
Wherein: 1, harmonic speed reducer; 2, hollow input shaft; 3, deep groove ball bearing; 4, bearing support; 5, bearing plate; 6, back-up ring.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
The hollow type harmonic speed changer with deep groove ball bearing of the utility model scheme, by the bearing fixing-assembly deep groove ball bearing 3 is fixed on the harmonic speed reducer 1, and reinforce by 6 pairs of deep groove ball bearings 3 of back-up ring, guaranteed the firm and stable of harmonic speed reducer 1 integral body, and when using installation, need not the requirement that too much adjustment can be satisfied use, save the installation time, and be convenient to the inspection and maintenance in equipment later stage.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
