Description
Technical field
The utility model relates to a kind of linear brake.
Background technology
Linear brake is called again electric pushrod, and built-in motor and speed changer are converted to rotatablely moving of motor the rectilinear motion of push rod, is usually used in doing on body the action of advancing or retreating. For example common body-building applied linear brake with treadmill and controlled the lifting angle of the running platform gradient, and utilize the range controlling mechanism of linear brake to carry out the running control of motor, and adjust the lifting gradient of needed running platform in good time.
Common linear brake generally comprises pedestal and is located at power source on this pedestal and transmission mechanism that screw rod forms, because needing relative pedestal, screw rod does High Rotation Speed, therefore between screw rod and pedestal, two groups of needle bearings of general employing are connected with gear, but because needle bearing rubbing surface is larger, make motor resistance large, under load, the life-span also reduces. In addition, two groups of needle bearing structures not only make linear brake complex structure, and assemble loaded down with trivial details.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of linear brake, adopts one group of ball bearing to substitute two groups of original needle bearing structures, not only simplified structure, and improve and reduce motor resistance, improve motor load.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of linear brake, comprise pedestal, motor, gear, latch and screw rod, and described motor is installed in this pedestal, and described pedestal has an axis hole; Described screw rod has an insertion end, and this insertion end is provided with a locating hole, and described insertion end is placed through in described axis hole; Described geared sleeve is located at the insertion end of described screw rod and is arranged in described pedestal, and this gear right flank has a right side storage tank; Described latch is inserted in the locating hole of described screw rod, and is positioned at this right side storage tank; It is characterized in that: in described axis hole two ends, be respectively equipped with clutch shaft bearing and the second bearing, the left surface of described gear has a left side storage tank, separately be provided with right pad, right cushion block, end thrust ball bearing, the left pad of thrust and the right pad of thrust, the insertion end of described screw rod is arranged in this clutch shaft bearing, right pad, right cushion block, gear, the right pad of thrust, end thrust ball bearing, the left pad of thrust and the second bearing successively, and the left pad of described thrust, end thrust ball bearing and the right pad of thrust are positioned at the left side storage tank of described gear.
As further improvement of the utility model, described pedestal has interior installing plate and plastic shell, and this interior installing plate is fixed in the medial surface of described pedestal, and this plastic shell is covered on outside this interior installing plate.
As further improvement of the utility model, the axis hole of described pedestal is also provided with axis hole cover plate near one end of described screw rod insertion end end.
As further improvement of the utility model, described motor comprises rotor, coil and bonnet.
The beneficial effects of the utility model are: this linear brake is owing to having adopted one group of ball bearing and gasket construction, replace original two groups of needle bearings and gasket construction, parts are reduced, simplify structure, simultaneously because ball bearing diameter is larger, can improve load bearing capacity, improve anti-wear performance, and improve motor life.

Detailed description of the invention
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is elaborated. But protection domain of the present utility model is not limited to following embodiment, the simple equivalence of in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.
As shown in Figure 1, a kind of linear brake, comprises pedestal 1, motor, gear 3, latch 4 and screw rod 6, and described motor is installed in this pedestal, and described pedestal has an axis hole 101; Described screw rod has an insertion end 61, and this insertion end is provided with a locating hole 62, and described insertion end is placed through in described axis hole; Described geared sleeve is located at the insertion end of described screw rod and is arranged in described pedestal, and this gear right flank has a right side storage tank; Described latch is inserted in the locating hole of described screw rod, and is positioned at this right side storage tank; In described axis hole two ends, be respectively equipped with clutch shaft bearing 71 and the second bearing 72, the left surface of described gear has a left side storage tank, separately be provided with right pad 8, right cushion block 9, end thrust ball bearing 10, the left pad 11 of thrust and the right pad 12 of thrust, the insertion end of described screw rod is arranged in this clutch shaft bearing, right pad, right cushion block, gear, the right pad of thrust, end thrust ball bearing, the left pad of thrust and the second bearing successively, and the left pad of described thrust, end thrust ball bearing and the right pad of thrust are positioned at the left side storage tank of described gear.
Described pedestal has interior installing plate 13 and plastic shell 14, and this interior installing plate is fixed in the medial surface of described pedestal, and this plastic shell is covered on outside this interior installing plate.
