Abstract
The utility model provides a technical scheme, particularly relates to a loop bar assembly combined with a sleeve head, which is characterized in that the loop bar assembly comprises a transmission shaft, a worm wheel, a worm and a housing; the transmission shaft penetrates through the central hole of the worm wheel and is fixed on the housing through a bearing, and the worm wheel is engaged with the worm; one end of the transmission shaft and one end of the worm extend out of the housing. The loop bar assembly provided by the utility model with the worm transmission principle and the compact structure not only can finish the same working task, but also reduce the wrench volume; and as the components in the technical scheme are made of material with lighter density, the weight of the wrench is reduced. The industrial mechanical wrench provided by the utility model with the advantages of labor conservation, compact structure, small volume and light weight is mainly used in the daily mechanical maintenance in which partial bolts are inconvenient to be dismounted.
Description
Technical field
The utility model relates to a kind of industrial machinery spanner, relate in particular to a kind of and pullover matching used loop bar assembly.
Background technology
In existing Wrench, fairly simple loop bar assembly is also arranged, but in actual production because the restriction of the time and space, cause inconvenience to the operator when using: existing spanner uses when finishing same job task, need bigger workload, and loop bar is longer, thereby carries also inconvenient, for some mechanical repairing work of the daily production of industry, a lot of troubles have been brought.The existing exactly loop bar of existing in prior technology weak point is wasted time and energy and is carried inconvenience, can not serve the production operation that is subjected to spatial constraints well.
Summary of the invention
The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of technical scheme is provided, and this programme can solve the problem that existing spanner workload is big, carry inconvenience.
This programme is realized by following technical measures: the utility model and pullover matching used loop bar assembly, and its characteristics are: include power transmission shaft and worm gear, worm screw and housing; Described power transmission shaft run through the worm gear centre bore and by bearing fixing on housing, worm gear and worm engaging; Power transmission shaft, worm screw have an end to expose housing.The concrete characteristics of this programme also have, and described power transmission shaft runs through housing; The end that described worm screw exposes housing is connected with common wrench or extension bar; Described bearing is a deep groove ball bearing; Described worm screw is adopted cast iron quality, and worm gear adopts bronze material, and power transmission shaft adopts the Fine Steel Casting iron material, and housing adopts cast iron quality.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing to adopt worm drive principle in this programme, utilizes the characteristics of its compact conformation, alleviates workload; In the time that same task can be finished, reduce the spanner volume; Because the technical program just has the lighter material of density, also can reduce the weight of spanner simultaneously.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings
Fig. 1 is the structural representation front view of the utility model specific embodiment.
Fig. 2 is the structural representation vertical view of the utility model specific embodiment.
Fig. 3 is the structural representation left view of the utility model specific embodiment.
Among the figure, 1 is housing, and 2 is worm gear, and 3 is bearing, and 4 is power transmission shaft, and 5 is worm screw.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing 1-3 as can be seen, the utility model and pullover matching used loop bar assembly is characterized in that: include power transmission shaft 4 and worm gear 2, worm screw 5 and housing 1; Described power transmission shaft 4 runs through worm gear 2 centre bores and is fixed on the housing 1 by bearing 3, worm gear 2 and worm screw 5 engagements; Power transmission shaft 4, worm screw 5 have an end to expose housing 1.
Loop bar assembly of the present utility model adopts worm drive principle, is that driving link, worm gear are that driven member comes transferring power with the worm screw, can reduce workload like this.Because loop bar assembly of the present utility model has compact conformation, less, the lightweight characteristics of volume, mainly is used in the place of part Bolt dismantling inconvenience in the industrial daily flight-line maintenance.
Loop bar assembly of the present utility model and pullover being used, operating personnel are at first with on the pullover power transmission shaft 4 that is connected loop bar assembly of the present utility model, pullover being enclosed within on the bolt to be removed that will be used then, make it rotation with hand operated worm screw 5, because worm screw 5 and worm gear 2 engagements, worm gear 2 will rotate thereupon, meanwhile, the power transmission shaft 4 that worm gear 2 central hole connect also can rotate synchronously with worm gear 2, the pullover of power transmission shaft 4 connections will drive bolt rotation to be removed, after the certain hour, bolt to be removed will be removed.
