Abstract
The utility model relates to a drilling pump with an integral gear pair, which belongs to the manufacturing technology field of the drilling pump of the drilling equipment. The driving gear pair of the utility model is composed of an integral initiative helical gear shaft, and an integral passive helical gear. A broad recess is arranged between the helical teeth of the integral initiative helical gear shaft and the integral passive helical gear, and the processing requirement can be obtained. The utility model solves the error problem that is generated by separate processing and assembling of the gear pair of the drilling pump in the prior art, while the generated error can not satisfy the accuracy requirement of the gear pair of the drilling pump; and the utility model also solves the problems that the dimension of the gear shaft needs to be enlarged and the driving proportion needs to be decreased in the integral processing of the helical gear shaft; when the broad recess which is left between the helical teeth of the integral initiative helical gear shaft and the integral passive helical gear is carried out, enough withdrawing location can be provided while processing; the material quality hardness and the processing accuracy can be guaranteed; because of the integral initiative helical gear shaft, the helical gear needs not to enlarge the diameter, and the driving proportion can be guaranteed.
Description
Technical field: the secondary drilling pump of a kind of overall gear, be used for oil, geological exploration and development drilling well, belong to the drilling pump manufacturing technology field of drilling equipment.
Prior art: in the prior art, owing to be subject to processing the restriction of equipment, the gear pair of drilling pump mainly contains two kinds of assembly type gear pair and narrow tool withdrawal groove gear pairs, the gear pair of modular construction is that the actual state according to the present gear machining apparatus of China designs, be to be assembled into gear pair behind the helical gear of machine shaping respectively, though this structure easy processing, owing in processing and assembling, can produce error, the get up requirement of the gear pair precision that just can not satisfy drilling pump of these accumulations of error; The tool withdrawal groove width of the narrow tool withdrawal groove gear of integrated type is generally 6mm-8mm, and therefore, it almost is impossible wanting not influence the another side flank of tooth when the heel teeth of processing herringbone tooth; Therefore, the shortcoming of prior art is: the assembly type gear pair is by being with initiatively and after passive herringbone tooth wheel set shapes respectively, assemble again, like this, in the process of processing and assembling, will produce processing and assembly error, these errors can impact the quality of drilling pump, in addition, because the requirement of split processing and assembling, the diameter of the driving gear of split assembling just needs big, can cause transmission ratios to reduce like this, the supporting of drilling pump impacted; The gear pair of the narrow tool withdrawal groove of integrated type has the suitable advantage of transmission ratios, but, adding man-hour owing to be subjected to the requirement of tooth face hardness, the employing finger cutter adds the different problem of space width that broken teeth and front and back processing can take place man-hour, and, because the hardness problem of machining tool also can cause the material of processed gear pair also will reduce hardness, therefore cause the working life of reducing drilling pump.
The purpose of this utility model is the shortcoming at prior art, according to the physical constraints of drilling pump support position, designs a kind of secondary drilling pump of integral gear that has wide tool withdrawal groove among the herringbone tooth of active herringbone gear shaft and passive herringbone gear.
Technological scheme: the utility model is achieved in that the utility model comprises support, driving gear pair and connecting rod 7, crosshead piston and fluid cylinder, bent axle 6, driving gear pair is made up of the active herringbone gear shaft 2 of an integral body and the passive herringbone gear 5 of an integral body, for the facility of processing, position limit according to the drilling pump support, design has tool withdrawal groove 1,4 between the herringbone tooth of integral body active herringbone gear shaft 2 and whole passive herringbone gear 5, and the tool withdrawal groove 1,4 of design can satisfy the requirement of processing.
The utility model has the advantages that: owing between the herringbone tooth of integral body active herringbone gear shaft and whole passive herringbone gear, leave wide tool withdrawal groove, so enough withdrawing positions are arranged adding man-hour, can guarantee the hardness of material and the precision of processing, owing to be whole active herringbone gear shaft, so, its herringbone gear also needn't increased diameter, so just can guarantee the ratio of transmission.
Marginal data:
Fig. 1 is the assembling partial cutaway schematic of whole initiatively herringbone gear shaft of the utility model and whole passive herringbone gear.
Specific implementation method: provide embodiment of the present utility model below in conjunction with accompanying drawing: the utility model comprises support, driving gear pair, connecting rod 7, crosshead piston and fluid cylinder, bent axle 6, driving gear pair is made of the active herringbone gear shaft 2 of an integral body and the passive herringbone gear 5 of an integral body, for the facility of processing, position limit according to the drilling pump support, design has tool withdrawal groove 1 between the herringbone tooth of integral body active herringbone gear shaft 2 and whole passive herringbone gear 5,4, the tool withdrawal groove 1 of design, 4 width is 60mm-130mm, the tool withdrawal groove 1 of whole processing and design, 4 can satisfy the requirement of processing technique requirement and gear pair hardness, the herringbone tooth of whole initiatively herringbone gear shaft 2 and whole passive herringbone gear 5 can be an involute garden stud wheel, also can be circular-arc gear; Add man-hour, whole initiatively herringbone gear shaft 2 and tool withdrawal groove 1 thereof process on a bearing, are installed on the bent axle 6 by many bolts 3 after whole passive herringbone gear 5 and the tool withdrawal groove 4 whole completion of processing thereof.
Claims (2)
1. an overall gear pair is crept into pump, comprise support, driving gear pair and connecting rod, crosshead piston and fluid cylinder, it is characterized in that: described driving gear pair comprises the active herringbone gear shaft of an integral body and the passive herringbone gear of an integral body, integral body initiatively between the herringbone tooth of herringbone gear shaft and whole passive herringbone gear design tool withdrawal groove, the width of tool withdrawal groove are arranged is 60mm-130mm.
2. the secondary drilling pump of a kind of overall gear according to claim 1 is characterized in that: the herringbone tooth of described whole initiatively herringbone gear shaft and whole passive herringbone gear can be an involute garden stud wheel, also can be circular-arc gear.
