Abstract
The utility model discloses an eccentric gear used for a vibration motor. The eccentric gear comprises a fixed eccentric block and a movable eccentric block sleeved on a motor shaft. The fixed eccentric block and the movable eccentric block are in a shape of sector. The movable eccentric block is provided with a locating pin which resists rotation of the movable eccentric block. The eccentric gear can change vibratory forces and amplitudes to achieve an objective of adjusting vibration effect. Adjustment is convenient and flexible, and the vibration motor gets various vibration effects.
Description
Technical field
The utility model relates to a kind of vibrating motor eccentric.
Background technology
Producing at present vibration in vibratory equipment, vibrating motor, vibrating machine much is to use eccentric rotary to produce vibration force.But eccentric part all is to be fixed on the rotating shaft in the running, and vibration force and amplitude are on-stream to be nonadjustable, and vibrating effect is single.
The utility model content
The purpose of this utility model provides a kind of vibrating motor eccentric of being convenient to adjust vibrating effect.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of vibrating motor eccentric comprises the fixed eccentric block and the movable eccentric block that are socketed in the vibrating motor rotating shaft, and fixed eccentric block and movable eccentric block are fan-shaped, and movable eccentric block is provided with the alignment pin that can the barrier activity eccentric block rotates.
Described movable eccentric block is provided with at least one pin-and-hole that is used for installing alignment pin.
Be equipped with a plurality of filler openings on described fixed eccentric block and the movable eccentric block.
Described fixed eccentric block and movable eccentric block form by the multi-disc stack combinations.
Described fixed eccentric block is formed by the multi-disc stack combinations, and described movable eccentric block is provided with a plurality of filler openings.
Described fixed eccentric block is provided with a plurality of filler openings, and described movable eccentric block is formed by the multi-disc stack combinations.
In the utility model, movable eccentric block is provided with the alignment pin that can the barrier activity eccentric block rotates, and can change vibration force and amplitude by changing direction of rotation; Movable eccentric block is provided with at least one pin-and-hole, can by adjusting the position of alignment pin, change vibration force and amplitude; Fixed eccentric block and movable eccentric block are designed to the multi-disc combining form, can adjust quality and barycenter that its sheet number changes eccentric block under stopped status, change the vibrating effect that eccentric block produces when participating in vibration; On fixed eccentric block and the movable eccentric block filler opening is set; can under stopped status, in filler opening, fill additives; change quality and the barycenter of eccentric block; and then the vibrating effect of change eccentric block generation when participating in vibration; easy to adjust, flexible, can make vibrating motor produce multiple vibrating effect.

Embodiment
As shown in Figure 1 and Figure 2, a kind of vibrating motor eccentric, comprise the fixed eccentric block 1 and the movable eccentric block 2 that are socketed in the vibrating motor rotating shaft 4, fixed eccentric block 1 and movable eccentric block 2 are fan-shaped, movable eccentric block 2 be provided with can the barrier activity eccentric block 2 alignment pins 3 that rotate.Movable eccentric block 2 is provided with the pin-and-hole 20 that at least one is used for installing alignment pin, can by adjusting the position of alignment pin 3, change vibration force and amplitude.Be equipped with a plurality of filler openings 11,21 on fixed eccentric block 1 and the movable eccentric block 2.Fixed eccentric block 1 is fixedly connected with by key 5 with rotating shaft 4, and movable eccentric block 2 can rotate along shaft axis; Jump ring etc. also can be adopted by nut 6 location in fixed eccentric block 1 outside.In the present embodiment, can change the vibrating effect that eccentric block produces when participating in vibration by change quality and the barycenter of eccentric block in filler opening 11,21 included packings, easy to adjust, flexible.
Fig. 4, Fig. 5 have expressed respectively the utility model clockwise and the state when rotating counterclockwise, in stopped status, by changing the position of alignment pin 3, can adjust the angle between fixed eccentric block 1 and the movable eccentric block 2, change vibration force and Oscillation Amplitude thereby be in operation, realize adjusting the purpose of vibrating effect; Along with the difference of direction of rotation, can change the angle between fixed eccentric block 1 and the movable eccentric block 2, can be in operation changes vibration force and Oscillation Amplitude.
Embodiment 2:
Such as Fig. 1, shown in Figure 3, fixed eccentric block 1 is formed by multi-disc 1 ' stack combinations, and movable eccentric block 2 is formed by multi-disc 2 ' stack combinations, and the length of alignment pin 3 will be able to stop all movable eccentric blocks 2.Other are with embodiment 1.Present embodiment, the sheet number that can adjust eccentric block under stopped status changes quality and the barycenter of eccentric block, changes the vibrating effect that eccentric block produces when participating in vibration.
During the utility model work, when rotating shaft 4 is rotated, fixed eccentric block 1 is with rotating shaft 4 rotations, under effect of inertia, movable eccentric block 2 pin 3 that is positioned stops, radially rotates freely and is obstructed, can only be in company with rotating shaft 4 synchronous rotaries, when direction of rotation changed, the position of being obstructed because of movable eccentric block 2 was different, thus between angle different, the rotating eccentricity piece (comprises fixed eccentric block 1, movable eccentric block 2) barycenter changes, the vibration eccentric throw changes, and according to Centrifugal vibration calculation of force formula, vibration force and eccentric throw are directly proportional, eccentric throw increases, vibration force increases, otherwise vibration force reduces; The vibration eccentric throw is directly proportional with amplitude, and eccentric throw increases, and amplitude increases, otherwise amplitude reduces; Therefore the change of alignment pin 3 positions or the change of rotating shaft 4 rotation directions can change vibration force and amplitude, reach the purpose of regulating vibrating effect.
In the utility model, fixed eccentric block 1 and movable eccentric block 2 all can for formed by the multi-disc stack combinations or its on filler opening is set, also can adopt other similar modes, can reach the quality and the barycenter that change eccentric block and get final product.
