Abstract
The utility model relates to an electric push rod, which belongs to the electric actuator. The utility model comprises a motor, a small gear, a big gear, a leading screw, a rod body, an outer cylinder, a slide key and a guide sleeve; the bearing of the leading screw is fixed on the outer cylinder directly; the inner side of the outer cylinder is provided with the slide key; the rod body is matched with the slide key; the utility model simplifies the complex structure of the existing electric push rod, adopts an external connection current relay which can be used as the overload protection of the push rod, and provides an inner mechanical protection simultaneously, such as a friction disc clutch; the overload protection of the electric push rod is more thorough and safe; the electric push rod can reduce cost and can prolong the service life.
Description
The utility model relates to a kind of electric pushrod, belongs to electric operator, is used for metallurgy, fields such as chemical industry, electric power, colliery.
Existing electric pushrod has associated mode and several patterns such as collapsible; push-and-pull partly has two kinds of common leading screw and ball screw shaft transmissions; Bearing Installation on the leading screw is on inner sleeve; slide in the inner sleeve letter outside; two back-up rings are set on the inner sleeve; accompany spring between the back-up ring; driving lever also is set on the inner sleeve to be reached and driving lever travel switch movingly; with travel switch in stirring by driving lever control the shaft overload and cause burn motor or damage the accident of parts; the electric pushrod of this structure; obviously exist baroque shortcoming; simultaneously; when interior stroke switch failure or sensitive poor performance, just do not have the power-off protection effect, damage casing even burn motor still inevitable.
The purpose of this utility model is exactly in order to overcome above-mentioned not enough sum of the prior art, and provides a kind of simple in structure, practical, relies on the electric pushrod of external impressed current relay control screw mandrel overload outage.
The purpose of this utility model is achieved in that it comprises motor, pinion, gear wheel, leading screw, shaft, urceolus, feather key, guide pin bushing, and the bearing on the leading screw directly is fixed on the urceolus, and the urceolus inboard is provided with feather key, and shaft along feather key movingly.
The utility model compared with prior art has the following advantages and good effect:
(1), simplified mechanical structure, be convenient to the assembling, reduced a spot diameter, be beneficial to design and installation and alleviated weight, saved material, reduced cost;
(2) use the peripheral hardware current relay, electric protection is reasonable, has reduced fault, is convenient to maintenance, has prolonged useful life;
(3) on the basis of original current relay protection, also can increase mechanical protection,, make protection more thorough, safer, can adapt to and in adverse circumstances, work as using friction disk clutch.
The explanation of accompanying drawing drawing:
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model embodiment 1 as shown in Figure 1, it is by motor (1), casing (2), pinion (3), gear wheel (4), leading screw (5), bearing (6), nut (7), shaft (8), feather key (9), urceolus (10), guide pin bushing (11) is formed, pinion (3) is connected with motor (1) axle key, gear wheel (4) is connected with leading screw (5) key, bearing (6) on the leading screw (5) directly is fixed on the urceolus (10), hand hay cutter is provided with feather key (9) in the urceolus (10), shaft (8) along feather key (9) movingly, shaft (8) is sleeved on the leading screw (5) by the nut (7) that is fixed together with it, guide pin bushing (11) is fixed with urceolus (10) end, and described pinion (3) and gear wheel (4) are installed in the casing (2).The course of work of this machine is: motor (1) drives pinion (3) rotation; pinion (3) drives gear wheel (4) rotation; gear wheel (4) drives leading screw (6) and drives leading screw (5) rotation; leading screw (5) drives nut (7) and slides along feather key (9) on the urceolus (10) and guide pin bushing (11) with this nut (7) shaft (8) welded together; finish the push-and-pull work of workpiece; when push rod transships; motor (1) rotation; shaft (8) is motionless; electric current increases in the circuit; be connected on the current relay action power dump in the circuit outward, shut down, play the effect of protection motor and body.
Embodiment 2 of the present utility model as shown in Figure 2, it by motor (1), casing (2), pinion (3), gear wheel (4), idle wheel (12), friction disk clutch shell (13), inner casing (14), sliding bearing (15), leading screw (5), bearing (6), nut (7), shaft (8), feather key (9), urceolus (10), guide pin bushing (11), form.Pinion (3) is connected with motor (1) axle key, pinion (3) is by idle wheel (12) and gear wheel (4) engagement, gear wheel (4) is connected with leading screw (5) by sliding bearing (15), fixedly connected with friction disk clutch shell (13) in gear wheel (4) outside, the inner casing of friction disk clutch (14) is shouldered (5) and is fixedlyed connected with silk, bearing (6) on the leading screw (5) directly is fixed on the urceolus (10), urceolus (10) inboard is provided with feather key (9), shaft (8) along feather key (9) movingly, shaft (8) is enclosed within on the leading screw (5) by the nut welded together with it (7), guide pin bushing (11) is fixed with urceolus (10) end, described pinion (3), idle wheel (12), gear wheel (4), friction disk clutch is installed in the casing (2).The course of work of this machine is: motor (1) drives pinion (3) rotation; pinion (3) drives shell (13) rotation of gear wheel (4) and friction disk clutch by idle wheel (12); because in the clutch; there is friction between the shell; inner casing (14) just rotates with shell (13); thereby inner casing (13) drives leading screw (5) rotation; as follows embodiment 1; when push rod (5) transships; shaft (8) is motionless; motor (1) still rotates, and produces between friction disk clutch inner casing (14) and the shell (13) and slides, and does not damage motor and body; protected complete machine safety, the friction disk clutch in the utility model also can be replaced by the monolithic diaphragm spring clutch.
