In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do simple the introduction to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is existing stepping motor sealed structural representation;
The stepping motor sealed structural representation that Fig. 2 is provided for the utility model embodiment.
Embodiment
The utility model provides a kind of stepping motor water-tight structure, to realize the purpose of the complete water-tight of stepping motor.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 2, the stepping motor sealed structural representation that Fig. 2 is provided for the utility model embodiment.
The stepping motor water-tight structure that the utility model embodiment is provided comprises dust cover 1, O RunddichtringO I2, O RunddichtringO II3 and rubber sleeve 4.
Wherein, dust cover 1 is installed between stepping motor leading screw 5 and the stepping motor shell 6, and contacts with the end face of the working head 7 of stepping motor, can prevent that foreign matter and mud dirt etc. from entering inside, Electric Machine Control chamber.
O RunddichtringO I 2 is installed between the junction block 8 and motor housing 6 of stepping motor, the O RunddichtringO has certain precommpression when mounted, it is subjected to the oil pressure effect to produce distortion in the machine operation process simultaneously, be close to the junction block 8 of stepping motor and the contact surface of motor housing 6, realize sealing between the two, thereby prevent that foreign matter, mud dirt and water etc. from entering working chamber from the gap between motor housing 6 and the junction block 8.
O RunddichtringO II3 is installed in the interface of motor housing 6, and it is fitted in the interface of motor housing 6 closely, has realized sealing between the two, thereby can prevent that foreign matter, mud dirt and water etc. from entering working chamber from the gap of the interface of motor housing 6.
One end of rubber sleeve 4 is installed in the surface of described motor housing 6, the other end is installed between the internal thread end face and dust cover 1 of machine operation 7, the surfaces externally and internally of rubber sleeve 4 has formed an airtight space, the gap that makes between dust cover 1 and the working head 7 and exist between motor housing 6 and the dust cover 1 is among its airtight space, realized the purpose of sealing, Wai Bu foreign matter, mud dirt and water etc. all can not penetrate in the working chamber from these places like this.
By technique scheme as can be seen, the stepping motor water-tight structure that the utility model embodiment is provided, dust cover, O RunddichtringO I, O RunddichtringO II and four water-tight structures of rubber sleeve, constituted a complete water-tight system, prevented that effectively foreign matter, mud dirt and water etc. from infiltrating the working chamber of motor from each connection position of stepping motor, realized the purpose of the complete water-tight of stepping motor, thereby guaranteed the operate as normal of stepping motor, avoided the situation of stepping motor cisco unity malfunction or inefficacy.
Further, for the working condition and the environment that satisfy stepping motor, the pagoda shape of selecting for use that rubber sleeve is preferential folds rubber sleeve, and the length that rubber sleeve trails is not less than the range of stepping motor.Under the stepping motor idling conditions, the working head of stepping motor puts under the ordering about of electric arteries and veins signal and contracts and move back, at this moment, rubber sleeve can be synchronized with the movement along with working head, the pagoda shape foldable structure of rubber sleeve can trail when putting in working head, thereby satisfy the range of stepping motor, like this, no matter stepping motor is static when still working, between dust cover and the working head and the gap that exists between motor housing and the dust cover all can be among the airtight space of rubber sleeve, and the rubber sleeve better elastic makes rubber sleeve be fitted in its connection position closely, like this, extraneous foreign matter, mud dirt and water etc. all not can from rubber sleeve the connection position penetrate into the working chamber, thereby realized the purpose of sealing, guaranteed the operate as normal of stepping motor.And the adaptive temperature of rubber sleeve is-100 ℃～300 ℃, 100 ℃ of the ambient temperatures when it satisfies stepping motor work fully.In addition, the shape of rubber sleeve also can be other shapes, as long as the spread length of rubber sleeve satisfies the range of stepping motor, the application is not limited this.
In addition, for make between rubber sleeve and the motor housing surface be connected more firm, one end of rubber sleeve can be installed on the described motor housing surface by binding agent or elastic collar, equally also can realize being connected between rubber sleeve and the motor housing surface for adopting binding agent and elastic collar simultaneously, thereby guaranteed the fastness of rubber sleeve when being synchronized with the movement more with working head, make between dust cover and the working head and the gap that exists between motor housing and the dust cover all can be among the airtight space always, thereby extraneous foreign matter, mud dirt and water etc. all not can from rubber sleeve connecting portion penetrate into the working chamber, guaranteed that more stepping motor works normally.
Equally, the other end of rubber sleeve can be installed between the internal thread end face and dust cover of machine operation head by binding agent, firm with what realize connecting, thereby extraneous foreign matter, mud dirt and water etc. all not can from rubber sleeve connecting portion penetrate into the working chamber, guaranteed that more stepping motor works normally.
Need to prove, between rubber sleeve and the motor housing surface be connected and the internal thread end face of rubber sleeve and machine operation head and dust cover between be connected also and can realize that the application is not limited this by other modes more well known in the art.
In sum, the stepping motor water-tight structure that the utility model embodiment is provided, dust cover, O RunddichtringO I, O RunddichtringO II and four water-tight structures of rubber sleeve, constituted a complete water-tight system, it has prevented that effectively foreign matter, mud dirt and water etc. from infiltrating working chamber from each position of stepping motor, realized the purpose of the complete water-tight of stepping motor, thereby guaranteed the operate as normal of stepping motor, avoided the situation of stepping motor cisco unity malfunction or inefficacy.
In addition, need to prove, more than all embodiment be based on all that stepping motor carries out, obviously, have among above-mentioned all embodiment that the stepping motor of any one is protection category of the present utility model equally in the water-tight structure.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
