Abstract
The invention discloses a motor exciting device, which comprises a shell, a stator and rotor equipped with said shell; the two ends of said shell being separately equipped with bearing block; the two ends of said rotor shaft passing separately across the bearing hole of said bearing block; the rotor shafts locating on the two sides of said bearing being separately equipped with eccentric mass block; the two ports of said shell being separately equipped with guard which is linked with said bearing block. Compared with the domestic prior vibration electromotor, the invented has a simple structure and a low cost as the same, and it prolongs the life time of the bearing and the foundation bolt with said structure; compared with the foreign inertial vibration source of fluid-pressure driving eccentric block, the invented has a much simpler structure.
Description
Technical field
The present invention relates to a kind of inertia-type vibrator, relate to a kind of motor vibration exciter that produces the inertia force vibration source specifically.
Background technology
At present, the known inertia-type vibrator overwhelming majority is a vibrating motor, and the structure of vibrating motor is: the armature spindle two ends of common motor are overhanging, and two groups of eccentric massblocks of symmetrical suit on two overhanging ends.When armature spindle rotated, eccentric massblock rotated the centrifugal intertia force that produces alternation thereupon and forms vibration source.Because vibrating motor armature spindle when rotation centrifugal intertia force is big and act on the cantilever end of bearing outer rotor shaft, vibrating motor bearing and foundation bolt are subjected to the power and the moment loading of alternation, so bearing wear is fast, temperature rise, foundation bolt is fracture easily also.Though the patent of invention (patent No. ZL01251697.X) that I am had adopts the redundant structure on the mechanics thoroughly to solve short and foundation bolt easy fracture two hang-ups of vibrating motor bearing life, but its structure is comparatively more complicated than the structure of known vibrating motor, make that the manufacturing workload is bigger, the assembling maintenance is also more loaded down with trivial details.
Summary of the invention
The objective of the invention is provides a kind of inertia-type motor vibration exciter at above-mentioned existing in prior technology deficiency.
The present invention can realize by following technology:
Motor vibration exciter of the present invention comprises casing, is arranged on the stator and rotor in the described casing, and described armature spindle is a statically determinate structure; The two-port of described casing is connected mutually with bearing block respectively; Described armature spindle two ends connect the dead eye that passes on institute's respective shaft bearing respectively; Symmetry is fixed with eccentric massblock respectively on the armature spindle that is positioned at described bearing both sides; Two-port at described casing is respectively arranged with the guard shield that is connected mutually with described bearing block.
With two bearings, two eccentric massblock pieces of symmetrical suit on the armature spindle of each bearing both sides.
The invention has the advantages that: armature spindle is fixed with≤6 (4 commonly used) foundation bolts with two bearings, each bearing block, in the bearing bilateral symmetry two eccentric massblocks is set, and armature spindle is a statically determinate structure; Each bearing block is fixed with 4 foundation bolts.After having adopted said structure, improved the force status of motor vibration exciter bearing and lower margin greatly.Therefore compare with other type inertia-type vibrator and have the following advantages: 1. compare with domestic used vibrating motor, not only structure is simple equally, cheap, and owing to adopted above architectural feature to improve the force status of motor vibration exciter, thereby prolonged bearing service life greatly, foundation bolt is easy fracture not also, has thoroughly solved two hang-ups of short and foundation bolt easy fracture of vibrating motor life-span; 2. compare with the inertia-type vibration source of external hydraulic-driven eccentric block, simple in structure, cheap, maintenance easily; 3. compare with the patent of invention (patent No. ZL01251697.X) that I am had, structure is simpler, and volume weight is little, and it is little to make workload, and price is low, uses easy to maintenance.
Description of drawings
Fig. 1 is that structure master of the present invention cuts open schematic diagram.
The specific embodiment
As shown in the figure, motor vibration exciter of the present invention comprises casing 1, is arranged on the stator and rotor 2,3 in the described casing 1, and described armature spindle is a statically determinate structure; The two-port of described casing 1 is connected mutually with bearing block 4 respectively; Described armature spindle two ends connect the dead eye that passes on institute's respective shaft bearing 4 respectively; Symmetry is fixed with eccentric massblock 6 respectively on the armature spindle that is positioned at described bearing 5 both sides; Two-port at described casing 1 is respectively arranged with the guard shield 7 that is connected mutually with described bearing block 4.
Claims (1)
1, a kind of motor vibration exciter comprises casing (1), is arranged on the stator and rotor (2,3) in the described casing (1), and it is characterized in that: described armature spindle is a statically determinate structure; The two-port of described casing (1) is connected mutually with bearing block (4) respectively; Described armature spindle two ends connect the dead eye that passes on institute's respective shaft bearing (4) respectively; Symmetry is fixed with eccentric massblock (6) respectively on the armature spindle that is positioned at described bearing (5) both sides; Two-port at described casing (1) is respectively arranged with the guard shield (7) that is connected mutually with described bearing block (4).
