Abstract
The utility model discloses a brake of an electric winch, which comprises a brake disc (1), a unidirectional bearing (2), a pair of brake friction plates (3) and a pair of mounting plates (4), wherein the brake disc (1) is axially limited at the tail end of a motor, the mounting plates (4) are fixed on a motor frame. The brake disc (1) is connected with a rotary shaft of the motor through the unidirectional bearing (2), and the brake friction plates (3) are tightly attached to two sides of the brake disc (1) and fixed on the corresponding mounting plates (4). The brake of the electric winch is effective in braking, simple in structure and convenient in adjustment.
Description
Technical field
The utility model relates to the electric capstan technical field, specifically is a kind of electric capstan drg.
Background technology
At present much human is all liked outdoor exercises, as often steer a ship, outdoor sports such as yacht, under the situation of harbour with a varied topography and harbour, often to use capstan winch; Or on the way run into when fault is saved oneself and to use capstan winch; Perhaps when carrying out other ships of field rescue, need use capstan winch.The kind of capstan winch has a lot, like electric capstan, hydraulic windlass.Hydraulic windlass uses trouble, and cost is high, and must be connected on the ship of hydraulic efficiency gear and could use, and its application is extensive, commonality is poor.Therefore, people use maximum still electric capstans, and electric capstan is to obtain power supply from storage battery to make motor operations drive capstan winch.
Present electric capstan comprises motor, transmission shaft, winding drum, reducing gear and support, power-transfer clutch and drg.This drg generally is located at the afterbody of motor, is used to prevent the motor counter-rotating.Present drg is to utilize the gear mesh stop tooth, thereby motor is stopped operating.Not enough below the electric capstan drg of above prior art exists: because must there be certain tolerance clearance in engagement between the gear, and these tolerance clearances can directly influence braking effect at glancing impact; And this drg is through gear mesh, complex structure, inconvenient debugging.
The utility model content
The technical matters that the utility model will solve is, provide a kind of good braking effect, simple in structure, debug electric capstan drg easily.
The technical scheme of the utility model is; A kind of electric capstan drg with following structure is provided; It comprises brake disc, unilateral bearing, a pair of brake strip and a pair of adapter plate that be fixed on motor frame on of axial limiting at the motor tail end; Said brake disc is connected with the rotating shaft of motor through unilateral bearing, and said a pair of brake strip is close to the both sides of brake disc, and is fixed on the cooresponding adapter plate.
Said brake disc is provided with the blade of inside side bending.
After adopting said structure, the utility model electric capstan drg compared with prior art has the following advantages: owing to the effect through unilateral bearing, when motor just changeed, the rotating shaft of motor did not drive brake disc through unilateral bearing; When motor reversed, the rotating shaft of motor drove brake disc through unilateral bearing, and brake disc receives the friction force of two brake strips and produce resistance, can't rotate, thereby make motor braking, this structure good braking effect, simple in structure, debugging convenience.
As improvement, said brake disc is provided with the blade of inside side bending, good heat dissipation effect.
Description of drawings
Accompanying drawing 1 is the utility model electric capstan drg and motor mounting structure scheme drawing.
Accompanying drawing 2 is section enlarged diagrams of the utility model electric capstan drg.
Shown in the figure, 1, brake disc, 1.1, blade, 2, unilateral bearing, 3, brake strip, 4, adapter plate.
The specific embodiment
Below in conjunction with accompanying drawing the utility model electric capstan drg is described further.
Like Fig. 1, shown in Figure 2; The electric capstan drg of the utility model; It comprises brake disc 1, unilateral bearing 2, a pair of brake strip 3 and a pair of adapter plate 4 that be fixed on motor frame on of axial limiting at the motor tail end; Said brake disc 1 is connected with the rotating shaft of motor through unilateral bearing 2, and said a pair of brake strip 3 is close to the both sides of brake disc 1, and is fixed on the cooresponding adapter plate 4; The fixed end that is every adapter plate 4 is located on the motor frame, and its free end is provided with brake strip 3.Brake disc 1 axial limiting specifically is meant at the motor tail end; The centre hole close-fitting of brake disc 1 has bearing carrier ring; Said unilateral bearing 2 is located in the bearing carrier ring; The outer end of brake disc 1 is provided with the brake disc pad, and brake disc pad lateral surface is provided with the screw that is spirally connected with machine shaft, like this with the brake disc axial limiting at the motor tail end.
Said brake disc 1 is provided with the blade 1.1 of inside side bending.
When motor just changeed, the rotating shaft of motor did not drive brake disc 1 through unilateral bearing 2; When motor reversed, the rotating shaft of motor drove brake disc 1 through unilateral bearing 2, and brake disc 1 receives the friction force of two brake strips 3 and produce resistance, can't rotate, thereby make motor braking.
Claims (2)
1. electric capstan drg; It is characterized in that: it comprises brake disc (1), unilateral bearing (2), a pair of brake strip (3) and a pair of adapter plate (4) that be fixed on motor frame on of axial limiting at the motor tail end; Said brake disc (1) is connected with the rotating shaft of motor through unilateral bearing (2); Said a pair of brake strip (3) is close to the both sides of brake disc (1), and is fixed on the cooresponding adapter plate (4).
2. electric capstan drg according to claim 1 is characterized in that: said brake disc (1) is provided with the blade (1.1) of inside side bending.
